The R-K NPR series pilot operated (remote) pressure regulator is ideal for hard to reach places and for situations where instant fluid pressure changes are needed (such as spraying or rinsing applications). When the valve is installed the pressure can be adjusted from 5-100 P.S.I. with an air pressure regulator to protect the system from pressure changes. It will provide accurate outlet flow if a series of pressure regulators are required for a system or operation. Wide working pressure range (5 to 100 PSIG) Top entry for easy in-line maintenance and a minimum water hammer. Air-to-open, spring to close. Molded bodies are standard for 1/2", 3/4"", and 1"" valves

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.
