3S035 Series

SKU: 3S035 Series

2/3 Direct Acting Solenoid Valve Normally Closed (3S035 Series)

 

When the valve is de-energized (left diagram), the plunger under the force of spring seals the main orifice, and port CYL connects with port EX. When the valve is energized (right diagram), the coil magnetic force pulls back the plunger and closes port EX, and connects port into CYL. 

 

To operate the 3S035 as a normally open diverter, you need to connect the supply air to Port No 1. The Top Port is the normally open port and Port No. 2 is the normally closed port. In the configuration, air goes from Port No. 1 to the Top Port when the valve is de-energized. When it is energized air will go from Port No. 1 to Port No. 2 and the Top Port will be shut off.
