The Asco 8220G007 Solenoid Valve (8220G7) is a high-capacity, pilot-operated valve designed to precisely and reliably control steam and hot water. With an extensive Cv of 13.5 and EPDM or PTFE options, this normally closed unit handles elevated fluid temperatures and pressures with ease. Once opened at higher pressure, the valve will remain open to 3 psi at the inlet.
