Rubber sleeve is the most important component for any type of pinch valves, it is the core of pinch valve.

Rubber sleeve provides corrosion & wear resistance, and pressure bearing capacity. The quality of pinch valve is as good as the quality of its sleeve.

Size range：

15~2000mm  1/2~80in

Pressure grade：

1~10Mpa 1:2 safety factor, which means bursting pressure is 2 times higher than the operating pressure.

Analysis of construction：

Inner Layer: adopt various kinds of rubber materials or formulas in order to fit for the high demanding applications involving abrasion, corrosion or high temperature, etc.

Reinforced layer: the perfect combination of synthetic rubber and synthetic fibre technology forms a unique reinforced skeleton, which enables the sleeve to bear pressure and fatigue.

Outer layer: Using Natural Rubber to protect and reinforce the flexure resistance of valve sleeve.

Opening tags: the middle part of the outer layer is equipped with opening tags to solve the problem of fixation and tensile strength of the inner sleeve and actuator, also to ensure full opening of valves in all process conditions.
