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.
Have one year operation so far with no issues
Operation of this solenoid at higher temps (> 175F) was very good. This solenoid was advertised as a 1/4" NPT female on all three ports. The exhaust port would not seal correctly to 1/4" NPT male fittings and appeared to not be a true 1/4" NPT female thread. I contacted the company and they did send out a replacement fitting.
