PVM - Series 75B Buried Service Manual Pinch Vave
Brand: Red Valve Company, IncThe PVM - Series 75B Buried Service Manual Pinch Valve is a reliable, maintenance-free, cost-effective valve designed for tough slurries and abrasive and corrosive chemical applications below ground.
This pinch valve was designed specifically for underground service. It is sealed with an epoxy coating and provides double containment.
Optional position indicators are available. There are no seats to grind, no stuffing boxes to repack and no packing gland to adjust.
The pinching action is on centerline so the valve closes on a smooth venturi and is self cleaning.
The heart of this unique valve is the durable, flexible rubber sleeve that is reinforced with high-strength fabric.
The sleeve, which is the only part of the valve exposed to the process, eliminates maintenance and the need for expensive, exotic body materials. Additionally, valve operation will not freeze and operating torques remain constant.
Series 75B Pinch Valves have the same face-to-face as gate, plug, or ball valves. ANSI 16.10 up to 6” size. sizes 8”, 10” and 12” Series 75Bs are available to ANSI 16.10 face-to-face with reduced-port sleeve.
