Product overview of Pneumatic high temperature single seat control valve
Pneumatic high temperature single seat control valve is composed of multi-spring pneumatic diaphragm actuator and low flow resistance high temperature regulating valve body. The multi-spring actuator is low in height, light in weight and simple in equipment. Pneumatic high temperature and high pressure regulating valve is equipped with electric-pneumatic valve positioner or pneumatic-pneumatic valve positioner, which can control the operation by inputting a 4-20mA control signal, and realize automatic adjustment and control of the fluid medium of the process pipeline.
Pneumatic high temperature single seat control valve working process
The Pneumatic high temperature control valve uses compressed air as the power source, the cylinder as the actuator, and drives the valve with the help of electrical valve positioner, converter, solenoid valve, position retaining valve and other accessories to realize switching value or proportional type. Adjustment, receiving the control signal of the industrial automation control system to complete the adjustment of the pipeline medium: flow, pressure, temperature and other process parameters. The characteristics of the pneumatic control valve are simple control, fast response, and intrinsic safety, and no additional explosion-proof measures are required.
