FRM2ACZSZWZH03-E - SPRING RANGE 100-275

THE TYPE FRM-2 IS DESIGNED TO FUNCTION AS A BACK PRESSURE OR ECONOMIZER VALVE IN CRYOGENIC CIRCUITS. THE BACK PRESSURE FUNCTION IS TO OPEN AT A PRESET PRESSURE AND RELIEVE INLET PRESSURE TO THE DISCHARGE SIDE INTO A LOWER PRESSURE. THE ECONOMIZER FUNCTION IS TO OPEN AT A PRESET PRESSURE, ABOVE THE PRESSURE BUILD SET PRESSURE, AND CONTINUE TO OPEN AS GAS HEAD PRESSURE FROM HEAT LEAK BUILDS DURING NON-USE PERIODS OF THE SYSTEM. THE ECONOMIZER BY-PASSES GAS HEAD PRESSURE DIRECTLY TO THE FINAL LINE CIRCUIT, WHEN SYSTEM DRAW RESUMES, TO DRAW DOWN THE EXCESS PRESSURE RAPIDLY AND RECLOSES BEFORE THE PRESSURE BUILD REGULATOR OPENS. THESE VALVES ARE SMALL AND COMPACT, YET HIGHLY EFFICIENT, MAKING IT SUITABLE FOR NUMEROUS APPLICATIONS THAT CALL FOR A SMALL, ACCURATE BACK PRESSURE REGULATOR. TYPE FRM-2 INCORPORATES A "FLOATING RING" DESIGN THAT PROVIDES FOR SMOOTH EVEN PRESSURE CONTROL
