ACL 207 Series Brass Solenoid Valve, Servo-Assisted Diaphragm, 2-Way Normally Open, NBR Seal, G 1/2" Female BSPP Connection, E207DB12

Parker Hannifin 7322BAN00

Parker 7322B Series — 2-way diaphragm pilot-operated solenoid valve, normally open, brass (Fluid Control Division Europe)

Parker 7322BAN00 — the 1/2" BSPP brass, NBR, normally-open pilot-operated diaphragm valve (also listed as PM143AN, and in Parker's current general catalogue as valve order number 443806W). 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 2.5 m³/h and a maximum differential pressure of 15 bar. Parker's opens from 0.10 bar differential against 0.15 bar here. 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 0.39 kg against Parker's 72 mm and 0.58 kg.

Danfoss 032U7180

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

Danfoss 032U7180 (EV220B 15B G 12N NO000) — the G 1/2" BSPP brass, NBR, normally-open servo-operated valve body, supplied without a coil. Danfoss has withdrawn this code as NBR is phased out of the EV220B 15-50 range. Not an identical part. Danfoss rates 032U7180 at a 15 mm orifice and Kv 4 m³/h; this valve is 12 mm and Kv 2.5 m³/h, so it passes roughly 62% of the Danfoss flow at the same pressure drop — size on flow before substituting. In its favour, this valve opens from 0.15 bar differential against Danfoss's 0.3 bar, and is rated to 15 bar against the Danfoss NO body's 10 bar. Body length is 59 mm against Danfoss's 80 mm, so allow for the pipework. Coil ordered separately: this valve takes a Series 3 coil, not a Danfoss one.
