Pneumatic Manual Control Valve

Pneumatic Manual Control Valve

Welcome to buy Pneumatic Manual Control Valve from us. Every request from customers is being replied within 24 hours. It is a compressed gas as the power source, with a cylinder as the actuator, and with the help of valve positioners, converters, solenoid valves, position-keeping valves, storage tanks, gas filters and other accessories to drive the valve to achieve switching or proportional adjustment, to receive control signals from the industrial automation control system to complete the adjustment of the pipeline medium: flow, pressure, temperature, liquid level and other process parameters. Pneumatic control valve is characterized by simple control, fast response, and intrinsically safe, without the need for additional explosion-proof measures.

Pneumatic control valve is one of the industrial process control instruments widely used in petroleum, chemical, electric power, metallurgy and other industrial enterprises.

It is usually a combination instrument formed by the connection of pneumatic actuator and regulating valve after installation and commissioning.

Applications and Features

A、the use and characteristics of pneumatic control valve use is a right-angle rotary structure, it is used with the valve positioner, can achieve proportional adjustment; V-type spool is most suitable for a variety of regulating occasions, has a large rated flow coefficient, adjustable ratio, good sealing effect, sensitive adjustment performance, small size, can be installed vertically. It is suitable for controlling gas, steam, liquid and other media.

B、Features: It is a right-angle rotary structure, consisting of V-shaped valve body, pneumatic actuator, positioner and other accessories; has an inherent flow characteristic of approximate equipercent ratio; adopts double-bearing structure, small starting torque, good sensitivity and induction speed; super shear capability.

C. Pneumatic piston actuator adopts compressed air as the power source, and drives the crank arm to make 90 degree rotation through the movement of piston to make the valve open and close automatically. Its components are: adjusting bolt, actuator case, crank arm, cylinder body, cylinder shaft, piston, connecting rod and universal shaft.
