Model Specifications
Valve type: Solenoid-controlled pilot-operated directional control valve
Function: 4-way, 2-position directional valve
Spool / offset: B2 = spring-offset spool
Center condition: N/A — B2 is 2-position, not a 3-position center-condition spool
Solenoids: Single solenoid
Pilot / drain: ET = external pilot and external drain
Mounting style: G = subplate mounted
Nominal size / interface: G06 = 20 mm / 3/4 in, NFPA D08, ISO 4401-08 / CETOP 8 / NG25
Coil voltage: A120 = AC120V, 60 Hz / AC110V, 50 Hz
Voltage range: 108–132 VAC at 60 Hz / 99–121 VAC at 50 Hz, ±10%
Coil current: 1.20 A inrush / 0.27 A holding at 60 Hz; 1.30 A inrush / 0.38 A holding at 50 Hz
Coil wattage: Not listed for A120 AC coils; Northman lists inrush/holding current instead
Wiring style: 10 = joint box / junction box with indicating lights
Seal suffix: No seal suffix shown on SWH-G06-B2-ET-A120-10; Buna-N would typically be N if specified
Max operating pressure: 310 bar / 4500 psi
Rated flow capacity: 500 LPM / 133 GPM max
Max tank line back pressure: External drain configuration; drain should return through the Y port rather than internally to T
