The R-K NLR series no lube pressure relief vlave is a 2-port valve, ideal for high purity applications where lubricants are not premitted, to relieve excess pressure taht may occur in the line or system. Adjust the threaded stem to obtain selected line or tank relief pressure. An outlet (tee) may be required on the inlet side of the valve. The valve starts to open as line pressure approaches set pressure between 10-80 P.S.I. The 1/4" valve is also available with a relief range of 60-125 P.S.I. It's designed so there is no metal contact with the fluid and top entry makes in-line maintenance easy. Suitable for harsh chemicals. Ideal for DI water and other high purity applications. Controlled pressure settings up to 100 P.S.I. available upon request."
