Standard valve sleeve manufactured by FENGCHI® is a very specialized component. Great care is taken to match the type of elastomer, pressure rating and temperature limits for customers' different process conditions, which ensures a long and maintenance-free service life. The full bore standard sleeve provides uninterrupted flow just like another piece of pipe and the flow remains streamlined when throttled.

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.
