Parker Hannifin 7322BEN00
Parker 7322B Series — 2-way diaphragm pilot-operated solenoid valve, normally open, brass (Fluid Control Division Europe)
Parker 7322BEN00 — the 1-1/4" BSPP brass, NBR, normally-open pilot-operated diaphragm valve (also listed as PM143.2EN, and in Parker's current general catalogue as valve order number 443809W). Offered as the closest equivalent, not an identical part. Both valves are rated to the same 10 bar maximum differential pressure. Parker's is the larger-bore build: a 35 mm orifice and a Kv of 25.2 m³/h against 30 mm and 10.2 m³/h here, and a heavier body at 145 mm port to port and 3.15 kg against 119 mm and 1.70 kg. Parker's also opens from 0.10 bar differential against 0.15 bar here. Size the flow against your duty before substituting; if you need Parker's flow at this port size, ask us before ordering. Body material, BSPP port thread, NBR seal, the 90 °C NBR media limit, the normally-open function and the maximum differential pressure are the same on both, and both are supplied without a coil. The electrical fitting is not the same: this valve takes a Series 3 coil with a DIN 46244 (9.4 mm) plug, where the Parker coil takes a DIN 43650 form A (18 mm) plug — an existing Parker cordset will not mate, so order the coil and plug with the valve.
