3C certificate pneumaticrelay valve

 

 Description 
The pneumatic actuator is an auxiliary device, it is actually a pneumatic actuator power amplifiers installed in leading the gas path. The power-amplified signal or the gas output pressure for enlargement or reduction (ratio of the output signal, and zoom in or out), to ensure that the signal is transmitted to a remote gas (0-300 m) to reduce the effects of delays in transmission. To adapt the scope of work of the actuator. Growth function. .
