Pneumatic Gate Valves, with Compressed air driven valves, seal face can only rely on media pressure to seal, that is, media pressure to seal face to the other side of the valve seat to ensure sealing surface, this is self-sealing.
Most of the gate valve is the use of forced sealing, that is, when the valve closed, to rely on external pressure to the valve seat, to ensure the sealing surface of the sealing.
The use of pneumatic gate valve features
1, use is a right-angle rotary structure, it can be used with the valve positioner to achieve proportional regulation; v-type Spool is suitable for all kinds of regulating occasions, with a large rated flow coefficient, adjustable ratio, good sealing effect, adjustable performance zero sensitivity, small size, can be installed vertical. Applicable to control gas, steam, liquid and other media.
2. Features: It is a right angle rotary structure, which consists of V type valve body, pneumatic actuator, positioner and other accessories; it has an approximately equal percentage of inherent flow characteristic; it adopts double bearing structure with small starting torque, with good sensitivity and speed of induction; shearing ability.
3. Pneumatic Piston actuator uses Compressed air as power source, through the movement of the Piston to drive the crank arm for 90 degree rotation, to make the valve open and close automatically. The utility model comprises an adjusting bolt, an actuator box body, a crank arm, a cylinder body, a cylinder shaft, a Piston, a connecting rod and a universal shaft.
4.the working principle of the Pneumatic Control Valve: The pneumatic control valve is composed of the executive mechanism and the regulating mechanism. The actuating mechanism is the thrust component of the regulating valve, which produces the corresponding thrust according to the magnitude of the control signal pressure, and promotes the action of the regulating mechanism.
The valve body is the regulating part of the pneumatic regulating valve. It is in direct contact with the regulating medium to regulate the flow of the fluid.
Pneumatic Gate Valve Application
