Gate valve is one of the commonly used cut-off valves. It is mainly used to connect or cut off the medium in the pipeline. It is not suitable for adjusting the flow of the medium. The gate valve is suitable for a wide range of pressure, temperature and diameter, especially for medium and large diameter pipelines.

1. Gate valve

The gate valve is one of the commonly used cut-off valves, mainly used to connect or cut off the medium in the pipeline, and is not suitable for adjusting the flow of the medium. Gate valve is suitable for a wide range of pressure, temperature and caliber, especially suitable for medium and large diameter pipelines

2. Shut-off valve

The shut-off valve is a commonly used shut-off valve, which is mainly used to connect or cut off the medium in the pipeline, and is generally not used to adjust the flow. The globe valve is suitable for a wide range of pressure and temperature, but it is generally used for medium and small diameter pipelines.

3. Throttle valve

The throttle valve controls the pressure and flow of the fluid by changing the cross section of the flow passage. It belongs to the category of regulating valves, but due to its structural limitation, it does not have the regulating characteristics of the regulating valve, so it cannot be used as a substitute for the regulating valve.

4. Butterfly valve

The butterfly valve is a valve that uses a circular butterfly plate that rotates with the valve stem as an opening and closing part to realize the opening and closing action. The butterfly valve is mainly used as a cutoff valve, and can also be designed to have the function of adjustment or cutoff and adjustment. At present, butterfly valves are increasingly used in low-pressure large and medium-diameter pipelines.

5. Check valve

Check valve is a valve that can automatically prevent fluid from flowing back. The disc of the check valve opens under the action of fluid pressure, and the fluid flows from the inlet side to the outlet side. When the inlet side pressure is lower than the outlet side, the valve flap is automatically closed under the action of the fluid pressure difference, gravity and other factors to prevent the fluid from flowing back.

6. Ball valve

The ball valve is a valve that uses a sphere with a circular through hole as the opening and closing part, and the sphere rotates with the valve stem to realize the opening and closing action.

7. Diaphragm valve

Diaphragm valve is a special form of shut-off valve, its opening and closing part is a diaphragm made of soft material, which separates the inner cavity of the valve body from the inner cavity of the valve cover

8. Plug valve

The plug valve is a valve that uses a plug body with a hole as an opening and closing part, and the plug body rotates with the valve stem to realize the opening and closing action.   

9. Plunger valve

10. Safety valves 

Safety valves are used as overpressure protection devices on pressure equipment such as boilers and pressure vessels. When the medium pressure in the protected equipment rises abnormally and reaches the specified value, the valve will automatically open, and then discharge in full to prevent the pressure from continuing to rise. When the pressure drops to another specified value, it will automatically close.

11. Pressure reducing valve

The pressure reducing valve is a kind of regulating valve. It reduces the inlet pressure to a certain required outlet pressure through the throttling of the opening and closing parts, and can use the energy of the medium to maintain the outlet pressure when the inlet pressure and flow change. Basically unchanged valve.

12. Trap

A trap is a valve used in steam pipe networks and equipment to automatically discharge condensed water, air and other non-condensable gases, and prevent water vapor leakage  

13. Drain valve   

14. Control valve

The valve is used in water and steam pipe network as a flow adjustment. The self-locking type can keep the pipe network in a balanced state.
