Product Description
This series of products has no sealing points and will not experience leakage; It is resistant to particle corrosion and will not clog when conveying liquids containing fibers. Its performance can be comparable to imported products, and it has advantages such as short supply time, reasonable price, and thoughtful service.
operational principle
When the control medium is not input, the cavity between the rubber sleeve and the valve body is connected to the atmosphere, and the rubber sleeve is in an outward tension state under fluid pressure. Due to the presence of reinforced fabric layers arranged at a certain angle within the sleeve, the axial and radial pressures of the sleeve are balanced, so the length and diameter of the sleeve will not change due to fluid pressure. When the control medium enters the cavity between the pipe sleeve and the valve body, the pipe sleeve deforms and intercepts flow under the pressure of the medium.
The QV pneumatic clamp valve is closed by a pressure difference of 2-3bar between the medium pressure and working pressure (depending on the mass of the elastomer). When the pressure supply is interrupted and the valve body of the clamp valve is ventilated, the liner inside the clamp valve is fully opened due to its great rebound force. The inner liner of the QV series MOLLET pneumatic clamp valve is located in the middle of two flanges in contact with the working medium.
