ANSI Class150 Cast Steel Single Action Double Action Pneumatic
Knife Gate Valve
Product introductioin:
Knife type gate valve is flat valve plate bottom with knife-type
oblique incision, with the function of cutting off the medium, so
that the valve is not blocked by the medium.
Knife type gate valve is also known as knife-type gate valve,
knife-type slurry valve, its opening and closing parts are the
gate, the direction of the movement of the gate is perpendicular to
the direction of the fluid, and the knife-type gate valve can only
be fully opened and fully closed, not adjusted and throttled.
Pneumatic knife gate valve matched with pneumatic actuator, it can
driven easily by compressed air, with single acting or double
acting function, with low starting torque, excellent sensitivity
and sensing speed.

Product features:
1. Efficient operational performance: The driving mode of the
pneumatic knife gate valve makes it characterized by fast response
and precise control. The immediacy of compressed air enables valves
to open or close in a short period of time, improving production
efficiency.
2. Safety and reliability: The design and manufacturing of
pneumatic knife gate valves are usually very sturdy and can work
stably in various harsh environmental conditions. In addition, due
to its excellent sealing performance, it can effectively prevent
medium leakage, thereby ensuring the safety of operation.
3. Easy to maintain: The design of pneumatic knife gate valves is
usually very simple, which makes their maintenance relatively
simple. Due to its lower friction coefficient and wear resistance,
the service life of the valve is also relatively long.
4. Strong adaptability: Pneumatic knife gate valves can adapt to
various fluid media, including gas, liquid, slurry, etc. At the
same time, its sealing material can also be selected according to
different media, further enhancing its adaptability.
5. Remote control: The pneumatic knife gate valve can be remotely
controlled through a control system, which is very important for
automated production lines. Valves can be easily opened and closed
through preset programs or manual operations.
