The working principle of the Rubber Sleeve Valve: The rubber sleeve valve rotates the handwheel to move the rubber sleeve valve stem up and down, thereby relaxing or squeezing the rubber sleeve to open and close the rubber sleeve valve.

Rubber Sleeve Valve can control flow, is easier to maintain, and has less resistance loss. It can replace expensive alloy steel valves and non-ferrous metal valves. However, the pressure and temperature resistance of rubber sleeve valves are limited by the material of the rubber sleeve. The general operating pressure is no more than 6 kg/cm². It is only allowed to be higher if the rubber sleeve of the rubber sleeve valve is reinforced. The operating temperature, except for fluorine rubber, is slightly higher. Generally, synthetic rubber sleeves are only allowed to be 80 degrees Celsius, and natural rubber is not allowed to exceed 60 degrees Celsius.
In addition to the advantages of ordinary rubber sleeve valves, the dynamic thin rubber throttle valve made of rubber sleeves has another outstanding advantage. The dynamic thin rubber throttle valve is "larger than the ordinary ones". The ratio of the flow rate through the valve to the channel area is called the specific flux. For control valves, specific flux is an important performance indicator. If the specific flux is large, the adjustment range will be wide, and the valve volume will be relatively small.
