FLUID POWER: Red Valve’sSeries 5200 Control Pinch Valve is designed to provide accurate, repeatable control of abrasive and corrosive slurries. The resilient elastomer sleeve produces a smooth venturi flow path that outlasts gate, plug, ball and even stellite-coated control valves. The reinforced elastomer sleeve is the only wetted part of the valve, eliminating the need for packing, valve seats and mechanical parts. A cone sleeve trim is most commonly used in throttling applications for tighter control and better rangeability. A broad choice of controls is available, including pneumatic, electro-pneumatic and “smart” positioners. The heavy-duty downstream wear area is ideal for throttling thick materials, such as dewatered sludge.
