The R-K NLF series no lube lressure regulator is ideal for protecting high purity applications from pressure changes where lubricants are not permitted.
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 15-100 PSI.
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, DI water, and other high purity applications.
Upstream Pressure Vacuum to 150 PSIG
Regulated Pressure 15 to 100 PSIG (1/4" to 1-1/2")
15 to 80 PSIG (2" to 3"
