BACK PRESSURE REGULATOR

The R-K series back pressure regulator is designed to protect piping and equipment from pressure changes where a constant regulated pressure on the up stream side of the valve is required. Prevents pumps from dead heading, over pressurization, pressure surge conditions, and maintains back pressure in closed loop systems. Adjustable screw and lock-nut makes it easy to accurately pre-set desired relief pressure Teflon (primary) and EPDM (back-up) diaphragms standard. No Metal contact with fluid Wide adjustable relief pressure range (10-125 PSI) Small pressure differential band from cracking point to fully open, and from fully open to close. Top entry makes in-line maintenance quick and easy. Ideal for DI water, harsh chemical, and other high purity applications.

The R-K AOV series air valve features a compact thermoplastic valve available in six models to handle a multitude of piping system functions. This patented valve is designed so there is no metal contact with the fluid, and can be operated in any position Air actuated at 40 to 80 PSI. Direct acting full flow with top entry for easy maintenance and minimum water hammer. Suitable for most harsh chemicals, pollution control, wet processing stations, plating equipment, chemical processing and water treatment applications.
