16 Accessories valves Body Used with Model material ( Meter) Maximum capacity Working pressure Application class* A-2882, A-2885 Aluminum M-5, M-7, M-10 100 GPM (380 L/min) 150 PSI 1 A-2883 Aluminum MA-5, MA-7 100 GPM (380 L/min) 350 PSI 10 * See table on page 9. Back check valves The soft-seat back check valves are designed for installation at the strainer inlet (LPG) or meter outlet (refined petroleum products) and are applied to prevent reverse flow (such as during hose rewind) and to eliminate counter advancement when the truck PTO is engaged. Back check valves include a soft-seat seal and built-in pressure relief to keep the meter, downstream piping, and delivery hose packed to a set pressure. Used on all LPG truck meters and in other applications as required. Solenoid and Digital Control Valves The 500 Series differential valve is for use with all MS, MSA and MSAA meters. The valve is offered in a steel body design with stainless steel tubing, pilot and fittings. Valves are supplied with single stage or two stage pilot operated preset control valves and operate in conjunction with mechanical and electronic presets. Body Used with Flange connections material ( Meter) ( ANSI 150 or 300) Working pressure Application class* Steel MS, MSA, MSAA Series 2", 3", 4" and 6" 150 or 300 PSI 1, 2, 10, 14, 16 * See table on page 9. Spring-loaded check valves for refined petroleum products Spring loaded metal-to-metal seat check valves are designed for mounting in the outlet collar of the strainer body, between the strainer and the meter inlet. Models are available for use with the standard air eliminator or high capacity air eliminator. Check valves are applied to maintain back pressure for increasing air/vapor eliminator efficiency and to prevent reverse flow of liquid. For refined petroleum products (fuel oil, gasoline, diesel fuel, etc).
