Parker Hannifin 7322BGN00
Parker 7322B Series — 2-way diaphragm pilot-operated solenoid valve, normally open, brass (Fluid Control Division Europe)
Parker 7322BGN00 — the 2" BSPP brass, NBR, normally-open pilot-operated diaphragm valve (also listed as PM143GN, and as part number 443811W in catalogue 8801/UK). This is a close match across the board: a 50 mm orifice against Parker's 50 mm, a Kv of 36 m³/h against Parker's 37.2 m³/h, the same 10 bar maximum differential pressure, the same brass body, BSPP port thread, NBR seal and normally-open function. One difference to note: Parker's valve opens from 0.10 bar differential where this one needs 0.15 bar, so on a very low-differential duty check the minimum pressure. The coil is ordered separately on both.
