S8F Series Solenoid Valve | Parker

The Parker S8F Series Solenoid Valve is a direct-acting, normally closed solenoid valve designed for refrigerant flow control in industrial and commercial refrigeration systems. It operates in a fully open or closed configuration, ideal as a pilot in refrigeration circuits. Available with a ductile iron or stainless steel body, it can withstand up to 27.6 bar (400 psi) MOPD and MRP. It features a Class "F" coil with a weather-resistant NEMA 3R/4 enclosure, stainless steel needle, and PTFE seats. Compatible with ammonia (NH₃) and other industrial refrigerants. Available in 120 VAC and 240 VAC / 60 Hz.
