Valve Definition Terms

A mechanical product with a movable mechanism used to control the flow of media in a pipeline.

2. Gate valve (gate valve, slide valve)

A valve whose opening and closing parts (gate disc) are driven by the valve stem and move up and down along the valve seat (sealing surface).

3. Globe valve (globe valve, stop valve)

A valve whose opening and closing type (valve disc) is driven by the valve stem and moves up and down along the axis of the valve seat (sealing surface).

4. Throttle valve (throttle valve)

A valve that changes the cross-sectional area of the passage through the opening and closing parts (valve disc) to adjust the flow rate and pressure.

5. Ball valve (ball valve)

A valve whose opening and closing type (sphere) rotates around a curve perpendicular to the passage.

6. Butterfly valve (butterfly valve)

A valve whose opening and closing type (butterfly disc) rotates around a fixed axis.

7. Diaphragm valve

Open-close type (diaphragm) is a valve that is driven by the valve stem, moves up and down along the axis of the valve stem, and separates the action mechanism from the medium.

8. Plug valve (cock)

Open-close type (plug) is a valve that rotates around its axis.

9. Check valve (check valve, non-return valve)

Open-close type (valve flap) is a valve that automatically prevents the medium from flowing back by the force of the medium.

10. Safety valve (safety valve, relief valve)

Open-close type (valve flap) is a valve that automatically opens and discharges when the medium pressure in the pipeline or machine equipment exceeds the specified value; it automatically closes when it is lower than the specified value, which protects the pipeline or machine.

11. Pressure reducing valve

Through the throttling of the opening and closing parts (valve flap), the medium pressure is reduced, and the valve behind the valve is automatically kept within a certain range by the direct action of the pressure behind the valve.

12. Steam trap

Valves that automatically discharge condensate and prevent steam leakage.

13. Draining Valves

Valves used for draining waste from boilers, pressure vessels and other equipment.

14. Low pressure valve

Various valves with a nominal pressure of PN≤1.6MPa.

15. Middle pressure valve

Various valves with a nominal pressure of PN≥2.0～PN＜10.0MPa.

16. High pressure valve

Various valves with a nominal pressure of PN≥10.0MPa.

17. Super high pressure valve

Various valves with a nominal pressure of PN≥100.0MPa.
