3/2 Way O-ring Groove Flange Stainless Steel Solenoid Valve Stem

3/2 Way O-ring Groove Flange Stainless Steel Solenoid Valve Stem

Three-way valves have three pipe connection s and two orifices. When one orificeis open, the other is closed, and vice versa. They are commonlyused to alternately apply pressure to and exhaust pressure from a valve actuator or a single-acting cylinder.

Three Types of Operations Apply
Normally Closed (NC)
When the valve is de-energized, the pressure port is closed and the exhaust port is con nected to the cylinder port. When the valve is energized, the exhaust port is closed and the pressure port is connectedto the cylinder port.
Normally Open (NO)
When the valve is de-energized, the pressure port is connected to the cylinder port and the exhaust port is closed. When the valve is energized, the pressure port is closed and the cylinder port is connected to the exhaust port.

Materials
The valve body must be compatible with the fluid; common materials are brass, stainless steel, aluminum, and plastic.

The seals must be compatible with the fluid.

To simplify the sealing issues, the plugnut, core, springs, shading ring, and other components are often exposed to the fluid, so they must be compatible as well. The requirements present some special problems. The core tube needs to be non-magnetic to pass the solenoid's field through to the plugnut and the core. The plugnut and core need a material with good magnetic properties such as iron, but iron is prone to corrosion. Stainless steels can be used because they come in both magnetic and non-magnetic varieties.For example, a solenoid valve might use 304 stainless steel for the body, 305 stainless steel for the core tube, 302 stainless steel for the springs, and 430 F stainless steel (a magnetic stainless steel) for the core and plugnut.
