The Asco 8220G075 Solenoid Valve (8220G75) is a pilot-operated, normally open valve built for sustained operation in hot water and steam applications. This model features a floating PTFE diaphragm for improved longevity, offering up to four times the service life of standard valves. Its compact operator and threaded bonnet make it a reliable and energy-efficient choice for maintenance-focused systems.
