Hansen HS8W/1022, 1/2" (20mm) Solenoid Valve, 1" Butt Weld Connections

This heavy-duty HS8A refrigeration solenoid valve is flanged, compact, and pilot-operated. It is now more dirt resistant, erosion resistant, and corrosion resistant than other similar refrigerant valves. A dirt controlling Teflon piston seal helps prevent sticking. The valve body has improved, erosion resistant flow passages. A proprietary coating on the valve body gives unmatched corrosion protection. The HS8A is used to provide on-off control of refrigerant flow. When the coil is energized, a pressure difference across the piston opens the valve seat. When the coil is de-energized, a spring closes the main Teflon seat to stop all flow.
