NORRISEAL CONTROLS - Check Valves

Series 7100 Non-Slam Lift Pistion Check Valve

The non-slam piston check valve is designed for the positive prevention of backflow in gas, air or liquid systems. Norriseal's use of a teflon spring energized piston seal ring allows for zero leakage between the piston and the guide. Piston check valves are available in sizes 1.00" through 10.00" and with various body and trim material for corrosive and low temperature applications. Norriseal piston check valves are ANSI rated for 150 to 2500 RF and RTJ flanges. Canadian made 1"-4" size valves are offered with standard NACE MR-01-75 trim and composition plug for positive shutoff at the plug and seat.
