Model 231Y-6 of our 3 Way valve line is a direct acting valve with a normally closed operating position. This specific valve has three ports in which media flows. While the valve is energized, the exhaust port is closed and media travels from the inlet port through the outlet port. While the valve is de-energized, the inlet port is closed and media travels from the outlet port through the exhaust port. It works across various media such as water, air, vacuum or other low viscosity fluids.
The port size is 1/4” inch female NPT threaded. The orifice size is 1.5mm and the CV value is 0.21. It can withstand pressure up to 115 psi (8 bar) and temperatures as low as -5 C and as high as 90 C. The seal material is NBR (Buna-N) or Nitrile Butadiene Rubber.
Wired in this 3-way solenoid to the power feeding a compressor, and it cycles between venting and feeding tanks with compressed air without issue. Before this part, the compressor would hard start or stall because the head wasn't venting. This was the perfect part to complete my project!
Is working well for my application. I am using it for 120 psi control air.
