Pneumatic valve classification

First, the main types of pneumatic valves:
1) Pneumatic V-shaped ball valve 2) Pneumatic O-cut ball valve 3) Torque cylinder ball valve 4) Electromagnetic diaphragm valve 5) Pneumatic straight-acting diaphragm valve 6) Electric valve Second, pneumatic V-type valve:
Use and Features A, the use of a right-angle rotary structure, which is used with the valve positioner supporting the ratio can be adjusted; V-valve spool is best suited for a variety of regulatory occasions, with a large flow coefficient, adjustable ratio, sealed Good effect, adjust the performance of zero-sensitive, small size, can be installed vertically. Suitable for controlling gas, steam, liquid and other media.
B, Features: Is a right-angle rotary structure, the V-valve body, pneumatic actuators, locators and other accessories; there is an inherent equal flow characteristics of similar hundred; using double bearing structure, the starting torque is small, with very Good sensitivity and speed of induction; Super shear capacity.
C, pneumatic piston actuator using compressed air as a power source, driven by the piston crank to carry out 90-degree rotation, so that the valve automatically open and close. Its components are: adjusting bolt, actuator box, crank arm, cylinder block, cylinder shaft, piston, connecting rod and cardan shaft.
D, pneumatic control valve works: Pneumatic control valve by the implementing agencies and regulatory agencies. Actuator is the thrust member of the regulating valve, which generates the corresponding thrust according to the magnitude of the control signal pressure and drives the adjusting mechanism to act. The valve body is the regulating part of the pneumatic control valve which is in direct contact with the regulating medium to regulate the flow of the fluid.
