The outlet port is connected to the exhaust port when de-energised and this path becomes blocked once the coil is energised, linking the inlet and outlet instead. Normally closed (NC) 3 way valves block the path between the inlet and outlet ports until the coil is energised. Unlike 2 way valves, 3 way solenoid valves will usually have 2 ports open at any one time and which ports are open while the coil is de-energised determines the function. Normally closed, normally open or universal? In addition to material options for the valve body and elastomers for compatibility with a wide range of gases and liquids.
Functional – manual override, manual reset…. Environmental – IP65, IP67, ATEX, IECEx, …. Unlike 2 way valves that are intended for isolation purposes, 3 way valves are used for directional control and have 3 function variants – normally closed (NC), normally open (NO) and universal (U).ģ way solenoid valves are used with liquid or gaseous media and can incorporate a huge variety of options: They have prewired connections which makes installation, maintenance, and control simple.3 Way or 3 port solenoid valves refer to the line connections in that there are 3 ports which makes them ideal for diverting flow from one path to another. SOLID pneumatic valves offer reliability, low power consuming, and long life. Manufacturing machines use pneumatic valve because they are ideal for automation. Aircrafts use pneumatic valves to control the pressure and flow of hot engine air to the windshield for the anti-icing and rain removal. Pneumatic types of valves can be found in a wide array of industries. This valve is made with an aluminum alloy and has an aperture of 3/8”. This is a 5/2 valve which means it has 5 ports 2 exhaust ports through which air is regulated as it flows out, 2 power ports that power the system, 1 supply port for the inlet of air pressure, and 2 flow positions. 
This valve allows pneumatic control of position, flow, pressure and temperature. It is also the interface between electronic controllers and pneumatic systems.
SOLID 3/8" NPT 5 Way 2 Position Pneumatic Aluminum Electric Solenoid Valve is a switch for directing air to any pneumatic device, usually an actuator, letting a relatively small signal to power a large device.
