3 Way Solenoid Valve (3 Port Solenoid Valve or Three Way Solenoid Valve)
Rotex offers wide range of 3 way Solenoid Valves ( also known as 3 port solenoid valves, Three way Solenoid Valve, 3 port solenoid valve, 3 way magnetic valve, 3 way electric solenoid valve)) for varieties of applications. These valves can be classified as 3 way Normally Closed solenoid valve, 3 way Normally Open solenoid valve, 3 way diverting solenoid valve and 3 way mixing solenoid valve based on the valve condition when the solenoid is energized.
In 3 way Normally closed solenoid valve, the inlet remains closed when the solenoid is in de-energized condition and outlet is connected to exhaust but inlet gets open to outlet when Solenoid is energized and exhaust gets close while in 3 way Normally Open solenoid valve, the inlet remains open when the solenoid is energized condition and outlet is closed when solenoid is in de-energized condition. 3 way solenoid valve Further can be classified as 3 way Direct Acting solenoid valve and Internal / External 3 way Pilot Operated solenoid valve
3 Way Direct acting solenoid valve are operated directly with the force of the solenoid and due to the same even in 0 bar inlet pressure or 0 bar differential pressure between inlet and outlet port such valve can fully open or close. In case of 3 port direct acting solenoid valve, solenoid force is used. Solenoid force counters with the pressure force and/or spring force to Open or Close the solenoid valve. Because of which there is a limitation on combination of orifice and pressure rating it can provide for a given solenoid force. There are some exception designs which are called pressure balance solenoid valve design but even Pressure balance solenoid valve designs are of higher cost and higher power consumption compare to their counter pilot operated solenoid valve design.
Pilot operated solenoid valve are as name suggest it uses pilot which is a smaller direct acting solenoid valve to operate a larger size valve. Here Pressure rating and orifice combination is no more limitation. There are two further categorization of pilot operated solenoid valve: internal pilot operated solenoid valve and external pilot operated solenoid valve. In internal pilot operated solenoid valve the pilot pressure is taken from the main stream of the inlet pressure while in external pilot operated valve the pilot pressure is given from different source of pressure then the inline pressure stream.
