The Asco 8220G011 Solenoid Valve (8220G11) is designed to handle high-flow steam and hot water, providing consistent sealing and reliable actuation. Its rugged brass body, EPDM or PTFE options, and low-wattage coil make it a go-to choice for heavy-duty rinse, sterilization, and process heating lines. Once opened at higher pressure, the valve will remain open to 3 psi at the inlet.
