Pinch valves are a unique type of valve designed to regulate or throttle fluid flow. They are used for different kinds of media: chemically active, abrasive, pulp-like (acid, pulp, cement, sand, etc.)
In pinch valves the valve body contains no seat and its gate does not have any sealing surfaces. The medium flows through a flexible sleeve that is pinched to control the flow with the help of the valve stem.
Pinch valves are designed for flow control of various media. Their sleeves are molded of different sorts of rubber:
• petrol-resistant rubber;
• oil-resistant rubber;
• chemically-stable rubber.
