ASCO (Emerson) SCE238D001V.230/50-60
Series 238 pilot-operated, built-in pilot, floating diaphragm, brass body, 2/2 NC (catalogue numbers SCE238D### and SCG238C###/E###)
ASCO Series 238 equivalent - 2/2 normally closed, pilot-operated brass solenoid valve with built-in pilot and floating diaphragm, G 3/8 BSPP, FPM seals, quoted against the 230 V 50/60 Hz build. Flow differs and should be checked before substituting: the ASCO part has a 12 mm orifice and Kv 2.4 m3/h, while this valve has a 10 mm orifice and Kv 1.7 m3/h, roughly 29% less flow. This valve is rated to 15 bar against the ASCO part's 10 bar and opens from 0.15 bar differential against 0.3 bar. The ASCO catalogue number includes a coil; this valve is supplied without one, so a coil should be selected separately.
