Description

Pneumatic Control Valve adopts pneumatic actuator and valve body. High pressure cascade control valve is suitable for high temperature and high pressure applications. It can effectively prevent liquid cavitation.reduce the flushing of fluid to the inner body and reduce noise. The Valve is especially suitable for the control of impure medium fluid. It worked by pneumatic actuator.

Features

1.Eesy to install and unloading. Kinds of connection will be suitable for any work place.2.No leakage and less noise. The sealing material will stop leakage.3.The closed structure is safe and stable. It could work for long time.4.Save power and automatical, less labor.
