Product Details

product description:


The pneumatic shut-off gate valve is an updated product of the pneumatic single gate. It changes the single gate has a large starting lifting force, the gate valve is easy to wear and has poor sealing performance, short service life, complex manual and automatic switching procedures and easy misoperation and other defects, thereby improving The tightness and service life of the valve.


It is suitable for the interception, release and pressure relief of process pipeline gas and liquid, and is widely used in two-position control such as petroleum transportation, oil storage tank farm, chemical equipment, metallurgy, power station light industry papermaking, oil storage and transportation, etc. System.


Application range:

The pneumatic shut-off gate valve has reliable performance, convenient operation switching and maintenance, and has been widely used in petroleum, chemical, shipping and other departments to control various media.


Structural features:


1. Pneumatic cut-off gate valve is equipped with pneumatic actuator and manual mechanism

2. The gate valve actuator adopts a double-cylinder structure. Compared with the single-cylinder pneumatic gate valve, the lifting force is doubled

3. Solved the shortcoming that certain valve plates of single-cylinder pneumatic gate valves were wedged in the valve body and could not be opened

4. Equipped with a buffer mechanism, which can effectively reduce the wear of the valve plate sealing surface and valve body sealing surface caused by the downward impact of the piston when the valve is closed, and it can also avoid the phenomenon of gate jamming
