Air operated Pinch ValvesAKO

As soon as the supply of compressed air/fluid is interrupted and the air operated Pinch Valve casing is vented or drained, the specially manufactured sleeve is opened by its rebound elasticity/resilience, enabling the pressure in the medium to flow through the full passage of the air operated Pinch Valves.

Pinch Valve MechanismUnderstanding How it Works

Pinch Valve Mechanism What is a Pinch Valve? A pinch valve offers a cost-effective and practical solution for controlling the flow of media through a pipe line or any other system. It comprises of a rubber sleeve, which is the only wetted part of the entire valve, and prevents the other components from contamination.Pinch valves have gained significant popularity in a number of industries

Operating Manual for Air operated Pinch Valves

.com . Only use the pinch valve when it is fitted (e.g. in a pipe). Use dry, oil-free and filteredcompressed air as a control medium to avoid corrosion and damage to the pinch valve and sleeve .

What is Pinch Valve ?Pinch Valve BodyPinch Valve Theory

Pinch Valve Body. Pinch valves have molded bodies reinforced with fabric. Pinch valves generally have a maximum operating temperature of 250 o F. At 250 o F, maximum operating pressure varies generally from 100 psig for a 1-inch diameter valve and decreases to 15 psig for a 12-inch diameter valve.
