Check Valves

Design Features
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.
Features
• PVC or CPVC construction - no metal components     • Quick response shut-off in any position     • Field replaceable Flex-Seal - EPDM or Viton®
• Assembled with silicon-free, water soluble lubricants     • Available with either spigot, flanged, grooved pipe or male threaded ends
• Sizes now available to 24" pipe size - call for information

PVC Utility Swing Check Valves are designed for horizontal installations, but may be installed in up-flow vertical position. Check valves must be installed with the valve’s FLOW arrow pointing in the direction of the flow. Flow velocity should not exceed 5 feet per second.

• Pressure Rating - 150 psi @ 73°F     • Maximum Service Temperature - 140°F     • EPDM seal for positive sealing
• Flow velocity < 5 ft./sec.
