Pneumatic Globe Valve – Flanged, Cast Steel / Stainless, API 600, High Temp
Pneumatic Actuator Gate Valve opens and closes the valve by driving the gate plate up and down by pneumatic actuator. This type of valve combines the convenient operation of a pneumatic actuator with the reliable sealing performance of a gate valve, and is widely used in piping systems in the petroleum, chemical, natural gas, water treatment and other industries.

Working Principle
The working principle of pneumatic actuator gate valve mainly depends on the power drive of pneumatic actuator. When the control system receives the command to open or close the valve, it will send a signal to the pneumatic actuator. After receiving the signal, the pneumatic actuator pushes the piston or gear and other parts to move through the internal pressure change, which in turn drives the valve stem and gate plate to lift and lower, and realises the opening, closing or regulating control of the valve.
Product features
High degree of automation: pneumatic actuator gate valve can be automatically controlled by circuit controller or gas source signal, or manually controlled, easy to operate.
Good sealing performance: the sealing surface of the gate valve usually uses rubber or metal sealing materials, good sealing performance, can ensure that the fluid does not leak.
Fluid resistance is small: the flow path design of the gate valve makes the fluid resistance is small, which is conducive to the smooth passage of the fluid.
Good regulating performance: some gate valves have a regulating function, you can adjust the position of the gate to control the flow of fluid.
Compact structure: the close combination of pneumatic actuator and gate valve makes the whole valve structure compact and occupies little space.
Safe and reliable: the pneumatic actuator has a fault self-diagnosis function, which can alarm and stop the work in time when there is an abnormality to ensure the safe operation of the system.
