The new and improved Beswick three-stage high pressure regulator, PRD4HP-1N7-1-6V, accurately reduces inlet pressures of up to 3,000 psi down to the 0 to 30 psi range.  A new valve seat design provides improved resistance to high temperatures. It can regulate outlet pressures accurately down to 0.5 psi.  Droop and rise effects are essentially eliminated even with wide swings in the inlet pressures.   This regulator provides maximum performance in a miniature size.  The PRD4HP-1N7-1-6V is designed with a 2 inch high resolution diaphragm for enhanced precision when regulating down to very low output pressures.  It is machined from corrosion resistant 316 stainless steel and assembled with Viton® seals.
