Series PVA Heavy Duty Pinch Valve

Series PVA: Reliable Flow Control for Demanding Applications

Cost-Effective Pinch Valve Performance for Abrasive and Corrosive Media

The Bray Series PVA Pinch Valve provides reliable on/off isolation, modulating control, and fixed-flow positioning for demanding industrial services. Its simple, robust design features a heavy-duty tri-layer elastomer sleeve with full-length reinforcement and quick-response lifting tabs that help the sleeve reopen as the pinch bars move to the open position.

Available in open and enclosed body styles, 16-bar and 25-bar pressure ratings, and sizes from 1/2 inch through 36 inches, the Series PVA supports a variety of regional flange-drilling patterns and sleeve materials. Actuation options include handwheel, bevel gear, pneumatic cylinder, hydraulic cylinder, and electric motor configurations for both on/off and modulating service. Designed for applications involving slurries, powders, sludge, acids, alkalis, and other challenging media, the Series PVA delivers dependable performance across mining, power, chemical processing, water and wastewater, pulp and paper, food and beverage, pharmaceutical, battery manufacturing, and recycling industries.
