Red Valve Co.

Control Pinch Valve

Red Valve’s Series 5200 control pinch valve is designed to provide accurate, repeatable control of abrasive and corrosive slurries. The elastomer sleeve produces a smooth venturi flow path that outlasts gate, plug, ball and stellite-coated control valves. The reinforced elastomer sleeve is the only wetted part of the valve, which eliminates the need for packing, valve seats and mechanical parts. The cone sleeve trim throttles applications for tighter control and range.

                    Drum Skimmer

                    Elastec drum skimmers are designed to handle multiple types of petroleum spills, from jet fuel to crude oil. The skimmers recover oil by rotating a drum through the oil-water interface. Oil sticks to the drum surface and is recovered inside the floating head. These drum skimmers respond to vegetable oil and bio-fuel spills as well, and are effective in recovering pollutants in marine environments and industrial pits.
