ACL 207 Series Brass Solenoid Valve, Servo-Assisted Diaphragm, 2-Way Normally Open, NBR Seal, G 2" Female BSPP Connection, E207IB50

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.

Danfoss 032U7185

Danfoss EV220B (15-50 range) — 2/2-way servo-operated solenoid valve, brass body, NO version

Danfoss 032U7185 (EV220B 50B G 2N NO000) — the G 2" BSPP brass, NBR, normally-open servo-operated valve body, supplied without a coil. Danfoss has discontinued this code as NBR is phased out of the EV220B 15-50 range, and G 2" is the largest threaded size Danfoss builds in this family. This valve matches it where fit matters: the same 50 mm orifice, the same 10 bar rating, and a 158 mm body against Danfoss's 162 mm. It is not identical on flow — Danfoss quotes Kv 40 m³/h against this valve's Kv 36 m³/h, about 90% of the Danfoss capacity at the same pressure drop — so size on flow before substituting. In its favour, this valve opens from 0.15 bar differential against Danfoss's 0.3 bar. One limit to check against your duty: fluid viscosity is capped at 25 cSt here against Danfoss's 50 cSt, which matters only on oil service. Coil ordered separately: this valve takes a Series 2 coil (13.2 mm bore, DIN 43650-A connector); a Danfoss coil is built for a 13.5 mm actuator and is not interchangeable.
