Pinch Valve – Series AJ

The Series AJ Pinch Valve features a simple, cost-effective design, perfect for dealing with problematic abrasive materials. The valve’s split body is designed to allow quick and easy sleeve replacement and is available in a variety of materials.

Replacement sleeves for the AJ Valve are available in several different types. Double wall sleeves are extra thick for greater wear resistance and longer life. Reduced port sleeves are also available. Food grade sleeves can be purchased for specialty applications. Please contact EVR or your local distributor for more information regarding replacement sleeves.

Series AJ Pinch Valves provide an effective means of flow control for hard-to-handle media such as slurries, sludges, and dry solids.

A flexible elastomer sleeve is contained in a cast metal housing. The annular cavity between the sleeve and the housing acts as the valve’s actuator.

As pressurized air or water enters the housing, the sleeve is pinched shut. Venting the pressure allows the valve to resume full normal flow.
