High Temperature Pneumatic Valve High Pressure Regulating Valve

FABIA High Temperature Pneumatic Valve High Pressure Regulating Valve

1. Description:

High temperature pneumatic valve is one of the industrial process control instruments widely used in petroleum, chemical, electric power, metallurgy and other industrial enterprises. According to the working principle of the pneumatic control valve, compressed air as the power source, the cylinder as the actuator, the use of electric valve positioner, converter, solenoid valve, positioning valve and other accessories to drive the valve, to achieve switching or proportional adjustment, receive the control signal of the industrial automatic control system, to complete the adjustment of the pipeline medium: flow, pressure, temperature and other process parameters.

2. Specification:

3. Features:

• Use and characteristics of the pneumatic control valve: it is a right-angle reverse layout, which can be used with the valve positioner to realize the share adjustment; V-type spool is most suitable for various adjustment occasions, with large rated flow coefficient, large adjustable ratio, good sealing, active adjustment function, small volume, and vertical installation. Suitable for controlling gas, steam, liquid and other media.
• Characteristics of high temperature pneumatic control valve: it is a right Angle reverse layout, composed of V-shaped valve body, pneumatic actuator, positioner and other accessories; With similar natural flow characteristics; Select double bearing layout, small starting torque, excellent activity and induction speed; Super shear ability.
• Pneumatic piston actuator uses compressed air as the power source and reverses 90 degrees through the moving arm of the piston to make the valve switch actively. The components are: adjusting bolt, actuator box, crank arm, cylinder, cylinder shaft, piston, connecting rod, cardan shaft.
• Working principle of the pneumatic control valve: The pneumatic control valve is composed of an actuator and a regulating mechanism. The actuator is the thrust component of the regulating valve, which generates the corresponding thrust according to the control signal pressure and promotes the action of the regulating mechanism. The valve body is a component of the pneumatic control valve, which directly contacts the regulating medium and regulates the flow of fluid.
