Plast-O-Matic plastic pinch valve yields high cycle life
The Series HSA all-thermoplastic, air-operated pinch valve from Plast-O-Matic features a long-lasting sleeve element with variable thickness and a tapered shape. The sleeve element is molded from EPDMh2, a new formulation of Ethylene-Propylene-Diene-Monomer, using a proprietary curing process for greater elasticity and durability. This elastomer, combined with the new design, enables the pinch element to achieve more than 1 million cycles under test conditions. The pinch valve has ½-in. true union connections, threaded or socket. It uses compressed air via a 1/8-in. NPT connection, and requires a common three-way air solenoid to operate, with 45 psi over line pressure for full closure. Valve body materials are offered in Geon PVC, Corzan CPVC, natural polypropylenee and Kynar PVDF.
