Pinch valves

Description

Hand and pneumatic operated pinch valves do not incorporate any stuffing box and are leaktight on all liquids, slurries, granular materials, powders, pastes, gases, acids etc.

Sleeve (internal rubber) is supported during opening and closing, and is easily replaceable without any special tools. The wide range of available elastomer materials enables an appropriate selection for each application and is a guarantee of perfect resistance to corrosion and abrasion.
