The R-K LPR series low pressure fluid pressure regulator is designed to protect piping systems and equipment from pressure changes. The adjustable screw and lock nut makes it easy to convert varying upstream pressure into accurate pre-set downstream pressure. Outlet pressure should be adjusted in a closed loop system within a range of 5-50 PSI. Provides excellant flow at low range settings. Top entry and parallel inlet and outlet ports to facilitate installation and avoid piping problems/ This patented pressure reducing valve is designed to keep the stainless steel spring totally isolated from the fluid chamber insuring no metal contact with the fluid. It is ideally suited for most harsh chemicals, and for systems that require additional pressure protection.

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.
