Pneumatic valve(Ningbo Lida Pneumatic Complete Co., Ltd : https://www.nblida.com/product/control-components/): A valve driven by compressed air.

Structure and characteristics:

A. The purpose is a right-angle rotation structure. It can be used with a valve positioner to achieve proportional adjustment; V-type spool is most suitable for various adjustment occasions. It has a large rated flow coefficient, a large adjustable ratio, and a good sealing effect. It has sensitive adjustment performance, small size, and can be installed vertically. Suitable for controlling gas, steam, liquid and other media.

B. Features: It is a right-angle rotation structure, which is composed of a V-shaped valve body, a pneumatic actuator, a positioner and other accessories; it has an inherent flow characteristic of approximately equal percentage; it adopts a double-bearing structure, which has a small starting torque and is extremely Good sensitivity and induction speed; super shearing ability. C. The pneumatic piston actuator adopts compressed air as the power source, and the movement of the piston drives the crank arm to rotate 90 degrees, so as to make the valve open and close automatically. Its components are: adjusting bolt, actuator box, crank arm, cylinder block, cylinder shaft, piston, connecting rod, cardan shaft. D. The working principle of the pneumatic control valve: the pneumatic control valve is composed of an actuator and an adjustment mechanism. The actuator is the thrust component of the regulating valve, which generates corresponding thrust according to the pressure of the control signal to push the regulating mechanism to move. The valve body is the regulating component of the pneumatic regulating valve, which directly contacts the regulating medium to regulate the flow of the fluid.

The structure and principle of pipeline pneumatic valve

Purpose It is a right-angle rotation structure, which can be used with a valve positioner to achieve proportional adjustment; V-shaped spool is most suitable for various adjustment occasions, with large rated flow coefficient, large adjustable ratio, good sealing effect and adjustment performance Zero sensitivity, small size, can be installed vertically. Suitable for controlling gas, steam, liquid and other media.
The pipeline type pneumatic valve is characterized by a right-angle rotation structure, which is composed of a V-shaped valve body, a pneumatic actuator, a positioner and other accessories; it has an inherent flow characteristic that is approximately equal to the percentage ratio; it adopts a double-bearing search structure with a small starting torque , Has excellent sensitivity and induction speed; super shearing ability.
