Coordinate the valve body, actuator, positioner, signal, fail action and specified accessories.
Project Documents
Define datasheets, GA drawings, test records, material documents and export requirements within the confirmed order scope.
OEM Supply Options
Discuss customer nameplates, repeat configurations and documentation requirements for approved OEM programs.
Start with the Control Duty
Valve selection should begin with what the valve must do under minimum, normal, maximum and upset conditions. Nominal line size or a previous model name is not enough to confirm the valve body, trim, seat, actuator or accessories.
Flow, Pressure, Temperature or Level Control
Use an engineered control valve when the valve must move through intermediate positions to regulate a process variable. Provide minimum, normal and maximum flow with the corresponding inlet and outlet pressures so valve capacity, operating travel, trim and actuator requirements can be reviewed.

Remote Isolation and On-Off Service
Actuated ball valves and butterfly valves can be considered for remote opening and closing. The final choice depends on size, differential pressure, medium, seat requirement, operating frequency, required closing time, fail action and installation conditions.

Three-Way Flow Control and Switching
Three-way control valves or three-way ball valves may be used for mixing, diverting, bypass or routing duties. State the required port arrangement, flow direction, operating positions and whether the duty is modulating or on-off.
Three-Way Globe Control Valve ↗Three-Way Ball Valves ↗
Check mixing, diverting and port arrangements. Confirm the permitted flow path and control duty for the selected design.

Compact Automation for Larger Line Sizes
Butterfly valves are often reviewed where compact quarter-turn operation is useful. Confirm the pipe and flange standard, pressure class, maximum differential pressure, seat construction, disc clearance, corrosion conditions and actuator torque requirement.

Define the Required Documents and Inspection Scope Before Order
Procurement documents should match the proposed valve type, configuration and order scope. A certificate or standards logo shown without product scope, legal entity and validity information is not enough to confirm applicability.
Specify Required Documents in Your RFQDocuments in the Confirmed Scope
The confirmed scope may include technical datasheets, GA drawings, material certificates or records, pressure and seat-leakage test records, actuator and accessory information, inspection records, packing and export documents, and OEM nameplate or marking information.
What to State in the RFQ
State the required standard and edition, valve type, size, pressure class, material and tag scope. Include the design, dimensional, testing, leakage and inspection acceptance requirements, certificate details, buyer review points, submission timing and document format.
Standards and Certificate Applicability
Send the applicable project standards with the inquiry. MacoTango will identify the proposed documents and note relevant inclusions, assumptions or exclusions. Do not assume that one certificate applies to every valve type, size, material, actuator package or market.
Testing and Inspection Scope
Pressure and leakage testing can be included within the mutually confirmed order and inspection scope. The procedure, acceptance criteria, reporting format, buyer or third-party inspection requirements and witnessing points must be agreed before order.
Configure the Valve, Actuator and Accessories as One Package
Once the control duty and RFQ data are defined, the valve, actuator and accessories should be reviewed as one operating assembly. The review focuses on four linked decisions: valve and trim configuration, material and sealing compatibility, actuator load and fail action, and the control, feedback and accessory failure sequence. The proposal should state the proposed scope and any assumptions or deviations requiring buyer approval.




Confirm the Valve and Trim Configuration
Translate the defined control duty into the proposed body pattern, flow direction, guiding or balancing arrangement, flow characteristic, seat and trim. Where cavitation, flashing, noise, erosion or corrosion has been identified, the trim decision should address that specific damage mechanism rather than use “severe service” as a general description.
Proposal output:
Proposed valve series and size, body and trim arrangement, flow direction, shut-off requirement, sizing basis and unresolved technical points.
Contact an EngineerMatch Materials and Sealing as a System
Body material alone does not define the complete material system. The trim, seat, packing and gaskets should be confirmed separately because each component has different chemical, pressure, temperature, friction and wear limits. Any uncertainty in fluid composition or material compatibility should remain visible for buyer confirmation.
Proposal output:
Component-level proposed materials, seat and packing construction, identified compatibility risks and items requiring buyer confirmation.
Contact an EngineerSize the Actuator for the Controlling Case
The normal operating point may not create the highest actuator load. Pneumatic or electric actuator selection should cover the most demanding opening, throttling and closing condition, including differential pressure, seat load and mechanical friction at the minimum available utility condition.
Fail open, fail closed or fail in place should follow the required process response. For an electric actuator, any required fail position also needs a defined stored-energy, spring-return or backup-power arrangement. For a modulating electric package, check command, feedback and failure behavior separately.
Proposal output:
Proposed actuator type, sizing basis, supply requirement, operating action, fail position, operating-time requirement, manual override and stated assumptions.
Contact an EngineerCoordinate Control, Feedback and Accessories
Positioners, solenoid valves, feedback devices and pneumatic accessories should be selected from the control and shutdown logic—not added as a standard component list. Confirm how the complete assembly responds to loss of air, power or control signal, and make sure accessory behavior does not conflict with the required valve fail action.
Proposal output:
Accessory schedule, input and feedback interfaces, failure-state sequence, and the included and excluded scope for mounting, tubing and wiring interfaces.
Contact an EngineerValve Selection for Industrial Project Conditions
Industry labels alone do not define the valve. Use the application links below to review the operating conditions, materials, control duties and document requirements that commonly influence selection.

Oil, Gas and Petrochemical Systems
Review pressure class, shut-off duty, actuator fail action, material requirements, operating frequency and any project-specified fire-safe, fugitive-emission or inspection requirements.

Chemical Processing
Provide the complete fluid composition, concentration, temperature and contaminants. Body, trim, seat, lining, packing and gasket compatibility may require separate review.

Power and Steam Systems
Include all operating cases for steam, condensate, boiler feedwater or utility service. Pressure drop, temperature, cavitation, flashing, noise and downstream velocity may affect valve and trim selection.

Water and Utility Pipelines
Confirm line size, pressure, water quality, corrosion conditions, cycle frequency, closing time, actuator torque and available electric or pneumatic utilities.

LNG and Low-Temperature Service
State the minimum operating and design temperatures, fluid phase, pressure, required materials, bonnet or stem arrangement, sealing requirements and applicable project documentation.

EPC, OEM and Packaged Equipment
Submit the valve list, tag requirements, repeat configuration, drawings, nameplate details, control interfaces and document schedule needed for the project or equipment package.
Inside Actuated Valve Manufacturing and Assembly
See selected manufacturing and assembly stages behind actuated valve packages—from component preparation and valve assembly to actuator mounting and accessory integration. Each image identifies the actual product and operation shown, giving buyers a factual view of the work behind the package.

Component Machining and Preparation
Valve bodies, trim parts and mounting components are prepared for the specified valve configuration.
Actuated Valve Quality Checks Before Delivery
Before release, we compare the assembled valve package with the confirmed order configuration. Applicable material, dimensional, pressure, leakage, functional and document checks depend on the valve type and project requirements. The quotation should state which checks, acceptance requirements and records are included.
Material Identification and Records
Where specified, material records or an agreed identification method are reviewed for the applicable valve body, bonnet and trim components. The required record should be traceable to the inspected valve or component.
Critical Dimensions and Interfaces
Dimensions and interfaces identified in the inspection scope are checked against approved drawings or agreed tolerances before assembly or release. Any required dimensional record should identify the measured feature and acceptance result.
Valve, Actuator and Accessory Check
Confirm that the actuator, mounting components, accessories, fail action, tag and nameplate match the approved valve package configuration before release.
Pressure, Leakage and Functional Checks
When included in the confirmed order scope, pressure, seat-leakage and functional checks follow the agreed procedure, test conditions and acceptance criteria. The required record should identify the specific valve package and the inspection result.
Final Identification and Packing Review
Before shipment, confirm the visible condition, markings, accessory installation, sealing-face protection, packing identification and shipping protection against the agreed release requirements.
Inspection and Project Documents
The confirmed document list defines what will be supplied with the order, such as datasheets, GA drawings, material records and inspection or test records. Third-party inspection documents are included only when specifically agreed.

Industrial Control and Actuated Valve FAQ
Start with the control duty. Use the Control Valve Series for modulating process control, self-operated regulation or control-valve accessories. Use the Actuated Ball Valve Series for quarter-turn shut-off, routing or V-port rotary control duties. Use the Actuated Butterfly Valve Series where butterfly-valve construction is suitable for the line size, pressure, medium, seat requirement and installation.
Provide the medium, minimum/normal/maximum flow, inlet and outlet pressures, operating and design temperature, valve size, pressure class, connection, materials, control duty, actuator supply, signal, fail action, quantity and required documents. Upload the project datasheet or valve list when available.
Yes, subject to the confirmed application and order scope. The package may include the valve body, pneumatic or electric actuator, positioner, solenoid valve, limit switches, filter regulator and other specified accessories. Final selection depends on the required thrust or torque, signal, fail action, site utilities and installation conditions.
Compare the available utilities, required operating speed, cycle frequency, fail-safe behavior, control signal, torque or thrust, ambient conditions and maintenance approach. Pneumatic spring-return actuators can provide a mechanical fail action where instrument air is available. Electric actuation may be considered where electrical power and remote control are preferred. The actuator must be sized for the actual valve duty.
Depending on the confirmed order scope, documents may include technical datasheets, GA drawings, material records, pressure or leakage test records, actuator information, inspection documents, packing documents and agreed export files. List every required document in the RFQ so availability and format can be confirmed before order.
Yes. Upload the existing datasheet, valve list, drawing or project specification. Clearly identify whether the inquiry is for a new project, replacement, tender, budget estimate, OEM program or repeat order. Additional operating data may be required if the existing document does not define all sizing, material or actuation conditions.
No. Certificate applicability depends on the certificate holder, product scope, model, size, material, standard edition and validity. State the required certificate or approval in the RFQ so its applicability to the proposed valve can be checked and documented.
