Parker Hannifin 7322BIN00
Parker 7322B Series — 2-way diaphragm pilot-operated solenoid valve, normally open, brass (Fluid Control Division Europe)
Parker 7322BIN00 — the 3/8" BSPP brass, NBR, normally-open pilot-operated diaphragm valve (also listed as PM143IN, and in Parker's current general catalogue as valve order number 443805W). Offered as the closest equivalent, not an identical part. Parker's valve has a 13 mm orifice, a Kv of 3.00 m³/h and a maximum differential pressure of 20 bar; this valve has a 12 mm orifice, a Kv of 2.2 m³/h and a maximum differential pressure of 15 bar. Parker's also opens from 0.10 bar differential where this one needs 0.15 bar. Confirm flow and differential pressure against your duty before substituting. Body material, BSPP port thread, NBR seal, the 90 °C NBR media limit and the normally-open function 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. It is also a smaller body: 59 mm port to port and 0.42 kg against Parker's 69 mm and 0.55 kg.
