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 rinsing applications). When the valve is installed, the pressure can be adjusted from 5-100 PSI with an air pressure regulator to protect the system from pressure changes. It will provide an accurate outlet flow if a series of pressure regulators are required for the system or operation. It can also be used as a normally closed air valve in systems where available air pressure is less than 20 PSI
This patented valve features no metal contact with the fluid and is designed for fail-safe operation, i.e., air-to-open, spring-to-close. Molded bodies are standard for 1z2”, 3/ 4” and 1” valves. Other features include top entry for easy in-line maintenance and minimum water hammer.
