For accurate gate valve selection, please send your valve size, pressure class, working temperature, media, flow direction, end connection, body material, bonnet type, wedge or gate design, trim material, operation method, required standards, testing documents and certificate requirements.
Gate valve selection should start from the actual pipeline duty, not only pipe size. Media, pressure class, working temperature, installation space, wedge or gate design, body material, seat material, stem type, end connection, operation method and required standards all affect the final industrial gate valve configuration.
Start with the media and whether the valve is used for full-open or full-closed isolation. Clean water, wastewater, steam, oil, gas, chemical liquid, pulp, powder and slurry may require different gate valve structures. Resilient seated gate valves are often reviewed for water and wastewater service, while knife gate valves are commonly considered for slurry, pulp and media containing solids. Gate valves are generally selected for isolation, not frequent throttling.

Confirm DN or NPS size, pressure class, working temperature, design margin and flow condition before selecting a gate valve. Water distribution projects may use resilient seated designs, while steam, high temperature, oil and gas or power station service may require cast steel, forged steel, pressure seal, metal seated or API standard wedge gate valves according to pressure rating and temperature range.

Match the gate valve type to the service condition. Wedge gate valves are widely used for industrial isolation, slab gate valves are reviewed for straight-through pipeline service, knife gate valves suit slurry or solids-containing media, resilient seated gate valves support water systems, and stainless steel gate valves are selected when corrosion resistance is important. The right type should balance sealing demand, media cleanliness, pressure class and maintenance access.

Body, bonnet, gate, seat, trim and stem materials should match corrosion risk, temperature, pressure, leakage requirement and medium compatibility. Carbon steel, cast steel, stainless steel, ductile iron, EPDM, NBR, metal seated, resilient seated and hardfaced trim options can be reviewed. Also confirm rising stem or non-rising stem: rising stem supports visible position indication, while non-rising stem can reduce installation height for buried or compact spaces.

Confirm the end connection, face-to-face dimension, flange standard and operation method before quotation. Gate valves can be supplied with flanged, threaded, socket weld, butt weld, wafer or lug connections, and operated by handwheel, bevel gear, pneumatic actuator or electric actuator. For project orders, also confirm API 600, API 602, API 6D, ASME B16.34, API 598, EN, DIN, JIS or GB requirements, plus drawings, certificates, inspection records and pressure test reports.

An industrial gate valve is a linear-motion isolation valve used to start or stop flow in a pipeline. When the handwheel, bevel gear, electric actuator or pneumatic actuator turns the stem, the gate or wedge moves up and down perpendicular to the flow path. In the fully open position, gate valves provide a straight-through bore with low pressure drop. In the fully closed position, the gate seats against the sealing surfaces to provide tight shutoff. Gate valves are commonly selected for water, wastewater, steam, oil, gas, power generation, petrochemical, mining, pulp and paper and general industrial pipeline isolation.
Multi-Turn Stem Operation: A handwheel, gearbox or actuator rotates the stem, converting rotary motion into vertical gate movement inside the valve body.
Full Open Flow Path: When the gate is lifted clear of the bore, the valve creates a straight-through flow path with minimal obstruction and low pressure loss.
Closed Isolation Position: When the gate moves down, the wedge, slab or knife gate contacts the seat to block flow and isolate pipeline sections for operation or maintenance.
On-Off Service Design: Gate valves are best used fully open or fully closed. They are generally not recommended for frequent throttling because partial opening can cause vibration, seat wear and gate damage.
Type and Standard Matching: Wedge, slab, knife, resilient seated, rising stem, non-rising stem, API 600, API 602 and API 6D gate valves are selected by media, pressure, temperature and installation requirements.
Gate valves are designed for full-open and full-closed service, helping isolate pipeline sections, equipment and process systems with dependable shutoff.
When fully open, the gate moves out of the flow path, making gate valves suitable for systems that need full-bore flow and minimal pressure loss.
Wedge gate valves, slab gate valves, knife gate valves, resilient seated gate valves, parallel slide gate valves and pressure seal gate valves can match different pipeline duties.
Rising stem gate valves provide visible open or closed position indication, while non-rising stem gate valves help reduce installation height in buried or compact spaces.
Resilient seated gate valves are often reviewed for water and wastewater service, while metal seated and hardfaced trim options support steam, oil, gas and higher temperature service.
Cast iron, ductile iron, carbon steel, cast steel, stainless steel, alloy steel, bronze, EPDM, NBR and Stellite trim options can be reviewed for water, steam, gas, oil, chemical and slurry media.
Handwheel, bevel gear, chain wheel, electric actuator and pneumatic actuator options can support local operation, remote control and automated plant systems.
API 600, API 602, API 6D, API 598, ASME B16.34, EN, DIN, JIS and GB requirements, plus drawings, datasheets, certificates and test reports, can support project approval.

A gate valve is mainly used for on-off isolation in pipelines. It lifts a gate, wedge or slab out of the flow path to open, and lowers it against the seats to shut off flow. Gate valves are commonly used in water, wastewater, steam, oil, gas, chemical, power generation, mining, pulp and paper and general industrial systems.
Gate valves are best used fully open or fully closed. They are generally not recommended for throttling because partial opening can create turbulence, vibration, seat erosion and gate damage. If continuous flow regulation is required, a control valve or globe valve is usually reviewed instead.
Wedge gate valves are widely used for industrial shutoff, slab gate valves support straight-through pipeline isolation, knife gate valves are selected for slurry, pulp and solids-containing media, and resilient seated gate valves are commonly reviewed for water and wastewater service where soft sealing and corrosion protection are important.
A rising stem gate valve moves the stem upward as the valve opens, giving a visible open or closed position indication. A non-rising stem gate valve keeps the stem height more compact, which can be useful for buried service, underground pipelines and installations with limited vertical space.
Common gate valve standards include API 600 for steel gate valves, API 602 for compact forged steel gate valves, API 6D for pipeline valves, API 598 for inspection and pressure testing, and ASME B16.34 for pressure-temperature requirements. EN, DIN, JIS, GB, ISO 5208 and EN 12266 can also be reviewed depending on the project specification.
Gate valve material should be selected according to media, pressure, temperature, corrosion risk, leakage requirement and installation environment. Cast iron and ductile iron are often reviewed for water service, carbon steel and cast steel for oil, gas, steam and power service, and stainless steel or alloy materials for corrosive or higher temperature applications.
Please provide gate valve type, DN/NPS size, pressure rating, working temperature, media, body and trim material, seat design, stem type, end connection, flange standard, operation method, quantity and any required standards, inspection reports, material certificates or pressure test records.
