1. Valve

It is used to control the flow of medium in the pipeline, and it is the general of mechanical products with movable mechanism.

2. Gate valve, slide valve

The on-off part (shutter) is driven by the valve stem and moves up and down along the valve seat (sealing surface)

A valve that the on-off (shutter) is driven by the valve stem and moves up and down along the valve seat (sealing surface)

3. Globe valve, stop valve

The on-off type (valve shutter) is driven by the valve stem and moves up and down along the axis of the valve seat (sealing surface).

A valve that the on-off(valve shutter) is driven by the valve stem and moves up and down along the axis of the valve seat (sealing surface).

4. Throttle valve

The valve that changes the cross-sectional area of the passage through the on-off (valve shutter) to adjust the flow and pressure

5. Ball valve

On-off type(balls) valve that rotates around a curve perpendicular to the passage. Such as fully welded ball valves.

6. Butterfly valve

On-Off type(butterfly) valve that rotates around a fixed axis.

7. Diaphragm valve

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

A valve that on-off (diaphragm) is driven by the valve stem, and moves up and down along the axis of the valve stem and separates the action mechanism from the medium.

8. Cock

On-off type (plug) valve that rotates around its axis.

9. Check valve, non-return valve

On-off type (valve clack) uses the force of the medium to automatically prevent the medium from flowing back.

On-off type (clack) valve that automatically prevent the medium from flowing back by using the force of the medium.

10. Safety valve, relief valve

Open-close type (valve clack) ,When the medium pressure in the pipeline or machine equipment exceeds the specified value, it will automatically open and shutterharge; when it is below the specified value, it will automatically close and shutterharge, and it will protect the pipeline or machine.

An on-off type(valve clack)valve that automatically open when the medium pressure in the pipeline or machine equipment exceeds the specified value and automatically shut down when the pressure is below the specified value

11. Steam trap

The valve that automatically drains condensate and prevent steam leakage.

12. Draining Valves

Valves are used for blowdown of boilers, pressure vessels and other equipment.

13. Low pressure valve

Various valves with nominal pressure PN≤1.6MPa.

14. Middle pressure valve

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

15. High pressure valve

Various valves with nominal pressure PN≥10.0MPa.

16.Super high pressure valve

Various valves with nominal pressure PN≥100.0MPa.

17. High temperature valve

It is used for various valves with medium temperature>450℃.

18. Sub-zero valve

It is used for various valves with medium temperature of -40℃～-100℃.

19. Cryogenic valve

It is used for various valves with medium temperature <-100℃.
