About Pinch Valves

Pinch valves include any valve with a flexible elastomer body that can be pinched closed, cutting off flow, using a mechanism or fluid pressure. Pinch valves are full bore, linear action valves so they can be used in both an off / on manner or in a variable position or throttling service. Some typical applications for pinch valves are medical, pharmaceutical, wastewater, slurries, pulp, powder and pellets. They can effectively control the flow of both abrasives and corrosives, as there is no contact between metal parts and the transport media.

Products & Services Related to Pinch Valves

Ball Valves

Ball valves provide tight shut-off and characterizable control. They have high rangeability due to the design of the regulating element, without the complications of side loads typical of butterfly or globe valves.

Butterfly Valves

Butterfly valves control flow through a circular disc or vane by turning the valve's pivot axis at right angles to the direction of flow in the pipe. They are normally used as throttling valves to control flow.

Check Valves

Check valves are self-activating safety valves that permit gases and liquids to flow in only one direction, preventing process flow from reversing. They are classified as one-way directional valves.

Globe Valves

Globe valves are linear motion valves with rounded bodies, from which their name is derived. They are widely used in industry to regulate fluid flow in both on/off and throttling service.

Needle Valves

Needle valves are small valves used for flow control in liquid or gas services. The fine threading of the stem and the large seat area allow for precise resistance to flow.

Solenoid Valves

Solenoid valves are devices that use a solenoid to control valve activation.

Solids Valves

Solids valves are used to control or regulate the flow of powder, granular and other bulk solid materials along a process line, or to and from process units, storage bins, conveyors and product packaging.
