Description & Features

Parallel Slide Gate Valve Closed


CV7200 Double disc parallel slide gate valve, the parallel slide disc without spring, applicable to shut off gas and liquid of pipeline, It is widely used in oil storage and transport, oil refining, chemical engineering, natural gas, oil field and other projects.


Avoid any flow turbulence, and minimize the pressure drop.


Disc never sticks or blocks.


Opening/closing torque is much lower than a corresponding wedge type valve, resulting in less expensive actuation systems.


Tight shut off, long life.


Pneumatic, electric and manual actuator available.
