MacoTango supplies industrial control valves and automated valve packages configured for flow regulation, process isolation and project-specific applications across oil and gas, chemical, power, water treatment and other process industries.
MacoTango supplies pneumatic and electric actuated ball valves for on-off isolation and modulating control in industrial process systems. Available configurations include O-type, V-port, metal-seated and three-way ball valves with matched actuator and accessory packages.
Actuated Ball Valve Series
MacoTango supplies actuated ball valve packages for industrial isolation, line switching and modulating duties. Browse pneumatic and electric O-port shut-off, V-port control, metal-seated and three-way ball valve configurations.
A proposed package can combine the valve, actuator, mounting components and required control accessories. Final selection depends on the submitted duty and confirmed project scope.
The actuator does not determine the valve function. Define what the valve must do in the process, then select the port, seat and actuator configuration around that duty.
Start with an O-port or another round-port on-off construction. The final choice should account for bore, valve construction, flow direction, seat system and the differential pressure present when the valve opens or closes.
Review O-Port Shut-Off Ball Valves
Use a characterized V-port or segmented ball design with a modulating actuator and position feedback. Final sizing must consider the operating flow cases, pressure drop, fluid properties and required working range rather than line size alone.
Review V-Port Control Ball Valves
Use a three-way construction only after the required port connections have been defined for every valve position. Confirm the actual port geometry from the proposed drawing rather than relying on a generic L-port or T-port label.
Review Three-Way Ball Valves
Review the complete material and sealing system when temperature, abrasive particles or solids may make a standard soft-seat direction unsuitable. A metal seat alone does not define the leakage rate, operating torque or expected service result.
Review Metal-Seated Ball Valves
A quotation is easier to review when it shows the proposed assembly and its scope, rather than listing only a model and price. The proposal should make the following items clear.
Identify the proposed ball valve type, body construction, bore, port arrangement, connection, principal materials, seat direction and required direction of operation.
Identify the proposed actuator type and action, mounting arrangement, supply conditions, control mode, feedback and included accessories.
State the operating or design cases used to review valve construction, materials, shut-off requirement, operating torque, actuator output and required failure response.
Separate the included valve, actuator, accessories and services from optional, excluded or buyer-supplied items so technical and procurement teams can compare quotations on the same basis.
List missing inputs, technical assumptions, alternatives and deviations that require buyer review. Open items should remain visible until they are confirmed.
Watch a MacoTango actuated ball valve package being assembled to see how the valve, actuator, mounting components and specified control accessories are combined and checked as one complete supply package.
Watch Our Assembly VideoSend an existing datasheet, valve list, piping specification or GA drawing. If no datasheet is available, use the checklist below. Mark unavailable values as TBD. The quotation should identify any assumptions and information still required for confirmation.
| Information Group | What to Provide |
|---|---|
| Duty and Flow Path | On-off, modulating, mixing or diverting duty; two-way or three-way arrangement; required flow path at each valve position. |
| Medium and Service Envelope | Fluid name and composition, phase, concentration, solids or contaminants; minimum, normal, maximum and design pressure and temperature; maximum differential pressure. |
| Valve Construction and Piping | DN/NPS, full or reduced bore, floating or trunnion construction, pressure class, end connection, piping or flange standard and face-to-face requirement. |
| Materials, Seats and Shut-Off | Required body, ball, stem, seat and seal materials; corrosion, erosion or compatibility concerns; required closure or leakage acceptance. |
| Cycling and Operating Time | Expected cycle frequency, required opening and closing time, long idle periods or continuous modulating duty. |
| Actuator Supply | Pneumatic air pressure and actuator action, or electric voltage, phase, frequency and duty cycle. |
| Signal, Fail Action and Accessories | On-off, floating or modulating command; required position after loss of air, power or signal; feedback, solenoid valve, positioner, limit switches, manual override and other accessories. |
| Site Conditions | Indoor or outdoor installation, ambient range, mounting orientation, available space and any specified hazardous-area or enclosure requirement. |
| Project and Commercial Data | Quantity, tag numbers, required document list, inspection requirements, nameplate information, packing, destination and export-document requirements. |
Requested documents and tests must be tied to the selected valve, actuator package and order scope. The quotation should state whether each requested item is included, optional, unavailable or still requires clarification.
The submittal should identify the proposed configuration, principal materials, pressure class, connection, actuator, accessories, dimensions and mounting interfaces.
Requested material records should identify the components and traceability scope they cover. If heat-number traceability, PMI or a specific certificate format is required, its applicability should be confirmed for the order.
The agreed test scope should identify the test object, medium, pressure, duration, direction and acceptance criterion. A shell test addresses the pressure-containing boundary; it does not replace a closure or seat-leakage test.
The agreed check should identify the assembled valve and actuator, supply conditions, direction of travel, stop settings, command signal, feedback and required response to loss of air, power or signal.
Confirm the final document index, tag and nameplate information, inspection records, packing marks, accessory protection and required export documents before shipment.
If document review, witness points, hold points or third-party inspection are required, state them in the RFQ so their feasibility and scope can be confirmed before order.
Tell us your working conditions and project requirements. Our team will help you compare suitable ball valve types, materials, operation methods and standards before quotation.
Tell us what the valve must control, isolate or route. Upload your datasheet, valve list, drawing or project specification so the valve series, materials, trim, actuation, accessories and document scope can be reviewed together. If information is incomplete, mark the missing items as TBD and include the available operating data.
Provide the duty, medium and composition, operating and design pressure and temperature, maximum differential pressure, DN/NPS, pressure class, connection, bore or port arrangement, material and seat requirements, required closure acceptance, cycle frequency, actuation, power or air supply, signal, feedback, fail position, quantity and document requirements. Mark unknown values as TBD.
Compare the available utilities, required operating time, cycle frequency, torque demand, control signal, feedback, site environment, maintenance approach and required response to loss of air or power. Pneumatic spring-return and electric fail-response arrangements work differently, so the required process position must be defined before the actuator is selected.

Use an O-port or another round-port construction primarily for on-off isolation. Use a characterized V-port or segmented ball design for modulating control. A V-port control valve still requires flow, pressure-drop, fluid-property, opening and actuator review; the port shape alone does not confirm the installed control result.
Provide a port schematic showing the required connections at every valve position. State whether the duty is mixing, diverting, bypass or equipment switching, identify the normal and fail positions and confirm whether temporary port interconnection during travel is permitted. Port letters alone are not sufficient without the matching drawing.
Actuator selection should use the controlling breakaway, running, closing and end-of-travel torque cases at the relevant differential pressure, temperature and minimum supply. Seat and seal friction, cycling, media effects and the selected safety or application margin must be tied to the exact valve and actuator configuration. Nominal valve size alone is not enough.
No. Metal seating is a construction direction, not a universal leakage result. The required closure test, medium, pressure, direction, duration and acceptance criterion must be stated for the selected valve. Do not use “zero leakage” unless a defined and applicable acceptance requirement supports that statement.
The required datasheet, GA drawing, material records, shell and closure test records, actuator information, functional checks, inspection records, tags, nameplates, packing and export documents should be listed in the RFQ. The quotation should confirm which items are included and identify any assumptions or deviations.
