This multi-purpose check valve provides an extremely low profile and very quick response to back flow without slamming. The special design requires no more space then a piece of pipe, and incorporates a flexible elastomer seal for long life, and is suitable for mounting in any position for greater versatility.
Technical Information
2″ through 8″ sizes are rated for 150 psi @ 73°F, 10″ and 12″ sizes are rated for 100 psi @ 73°F. As a general guideline, opening and closing pressures will range from .2 to .5 psi for horizontal applications. Opening pressures tend to decrease in large size valves. Valves installed in vertical up-flow applications will require slightly higher pressures.
