Know About Pneumatic Knife Gate Valve

The pneumatic knife gate valve has the advantages of simple and compact structure, reasonable design, light-weight material, reliable sealing and easy operation. The pneumatic knife gate valve is driven by compressed air. Pneumatic knife gate valve uses pneumatic actuator to control the valve, so as to realize the opening and closing of the valve. It has the advantages of flexibility, small size, smooth passage, small flow resistance, light weight, easy installation and disassembly, etc.

It can work normally under the working pressure of 1.0MPa-2.5MPa and the operating temperature of -29~650°C.The gate of the knife gate valve has a shearing function, which can scrape off the adhesive on the sealing surface and automatically remove the sundries. The stainless steel gate can prevent the seal leakage caused by corrosion.

Frequently Asked Questions

As the name suggests, Normally Open valves allow air to pass when they are not energized (or actuated). Normally Closed valves must be actuated to allow air to pass.
We have passed 1 million times of product quality test, and obtained the certificate.
The air actuator does not have a manual override, but a manual override is provided with optional direct mount solenoid valves.
See product specifications. Generally, smaller valves less than 2 inch pipe size, cycle in about one second. Larger valves up to 6 inch pipe, cycle in about 1.5 seconds. A cycle is per 90° rotation
