WARNING: Installation, usage and maintenance of this product must be in compliance with all Engineered Controls International, Inc. instructions as well as requirements and provisions of NFPA #54, NFPA #58, DOT, ANSI, all applicable federal, state, provincial, and local standards, codes, regulations and laws. This valve must remain in the closed position except during product transfer. A line break downstream of the pump may fail to actuate the excess flow valve as the pump may limit flow. If a break occurs in the system, or the excess flow closes, immediately shut down the system. Inspection and maintenance on a periodic basis is essential. How the Valve Works: 1. Normally Closed While the valve is closed, liquid flows into the INLET PORTS, and through a channel in the PISTON into area A. It also flows down through the PRIMING CHANNEL in the valve body, into area B beneath the valve seat -- and into area C to prime the PUMP. Installation, disassembly, repair and maintenance must be performed only by qualified personnel. Be sure all instructions are read and understood before installation, operation and maintenance. These instructions must be passed along to the end user of the product. CAUTION: Contact or inhalation of liquid propane, ammonia and their vapors can cause serious injury or death! NH3 and LP-Gas must be released outdoors in air currents that will insure dispersion to prevent exposure to people and livestock. LP-Gas must be kept far enough from any open flame or other source of ignition to prevent fire or explosion! LP-Gas is heavier than air and may not disperse or evaporate rapidly if released in still air. 2. Pump on — Valve Opening When the pump is started, differential pressure transmits through the 1 /4” piping into chamber D, lifting the PILOT STEM. This opens the seat between the stem and piston at E. Pump suction then evacuates the tank pressure in area A, which becomes equal to the pump suction pressure. Piston A A Inlet Ports Priming Channel Piston E Pilot Stem B 1 /4” Pump Discharge Line D C Pump 3. Pump On — Valve Open Tank pressure exerted on the X-RING SEAL forces the PISTON up to open the valve. This rotates the INDICATOR SLOT to its vertical (valve open) position. The pump differential pressure in area D holds the PILOT STEM and PISTON open. Approximately 18 psig pump differential pressure is required to open the valve and approximately 8 psig differential pressure will hold the valve open. 4. Pump Off — Valve Closes With the pump shut off, the pressure in area D which holds the valve open, bleeds out through the # 60 DRILL ORIFICE. This loss of pressure permits the SPRING to push the PILOT STEM down and re-seat at point E. Since pressures are equal above and below the PISTON, with no sustaining pressure in area D, the SPRING forces the valve closed. The INDICATOR SLOT rotates to the horizontal (valve closed) position.
