The most recent addition to the ProFlex line of rubber check valves is the introduction of the Series 730 molded rubber light weight check valve. This type of check valve is available ranging in sizes from 3/4” to 4” pipe diameter and can be directly mounted to the OD of schedule 40 pipe. The complete size range is supplied with a ¾” -316 Stainless Steel Worm Gear clamp ready for quick set up and installation. Through its rubber bill, media will pass creating a low head loss valve, complete with a zero back flow feature. Its ability to prevent backflow into the mating pipe system is a quality aspect in “checking” pipes or tanks that often have problems with back flow problems.
