STC 2S020-1/4A-2-D-V 1/4" NPT Direct Acting 2 Way Stainless Steel Solenoid Valve, 24VDC DIN

1/4" NPT Direct Acting 2 Way Normally Closed Stainless Steel Solenoid Valve (24VDC DIN), Viton Seal, 9mm Armature, 200C Coil

To Connect the Valve Inlet & Outlet: Connect the inlet & outlet to the valve ports according to the flow direction arrow marked on the valve

To Install the Coil: Put the coils on to the armature tube of the valve. Place the lock washer & nut on to the armature tube. Hand tighten the nut, then use a wrench to tighten the nut another quarter-turn. Do not over-tighten the nut, as it may cause the armature tube to fail prematurely.

Safety Note: Standard valves are supplied with continuous duty coils. The proper class of insulation for the service is indicated on the coil body. The coil temperature may rise significantly if energized for extended periods-this is normal. Although the coil is made of flame-retardant material, misuse of the coil could create fire hazards & generate smoke and/or a burning odor. If these conditions are encountered, the coil temperature has risen above safe levels and the power should be disconnected immediately.

Operation: This valve is a two-way, normally closed, direct-acting valve & does not require a minimum differential pressure to operate. As shown in the diagrams below, when the coil is de-energized (left diagram), the plunger rests on the main orifice & is held in place by the plunger spring force, sealing the valve. When the coil is energized (right diagram), the solenoid lifts the plunger & allows the working medium to flow through the orifice. The working medium & flow direction are indicated in purple in the diagrams.
