Air Operated Pinch Valves Type R
Air Actuated Pinch Valves offer a cost-effective solution to flow control problems. The secret is in the rubber sleeve – the valve’s only wetted part. Actuation of the valve, the pinching action, is accomplished by air or hydraulic pressure placed directly on the elastomer sleeve. The valve body acts as a built-in yactuator, eliminating costly hydraulic, pneumatic, or electric operators. The sleeve’s flexibility allows the valve to close droptight around entrapped solids. In general, 25 psi over line pressure is required for full closure of air actuated pinch valves
Type A Air Operated Pinch Valve

The only valve that closes “drop tight” on solids
Automatic valve using plant air
High cycle valve
No cavities or dead spots to bind valve operation
Full port design
Not affected by harsh external environments
No packing to replace or maintain, ever.
Cost effective and maintenance free.
Materials of Construction
Elastomer reinforced with high strength fabric body
Available Elastomers
Red Valve’s all new Type R all-elastomer pinch valve is an ideal valve for water, chemical, solids, and slurry applications. The valve is easily installed between two pieces of pipe with hose clamps. Simply add 20 psi air pressure over line pressure and the valve closes drop tight. For example: Process line pressure is 45 psi; 20 psi over line pressure, or 65 psi, closes the valve. It’s that simple!
The Type R has all the advantages of a Pinch Valve: no packing gland or seat crevices; this full port valve eliminates bridging or slurry dewatering blockage associated with metal seated valves. Each time the valve flexes it self-cleans. The Type R Pinch Valve is ideal for use with pulse type control systems. The lightweight design of the Type R Pinch Valve makes pipe supports unnecessary. The type R is an excellent valve to have in stock for an instant valve repair or to isolate a pipeline.
The valve body is elastomer reinforced with fabric, bonded to the inner sleeve – the only wetted part. Air connection is a 5/16” valve stem. The unique one-piece design of the Type R Pinch Valve eliminates the need for actuators, making this the most affordable, maintenance-free automatic valve available to industry
