The Asco 8015B211 Solenoid Valve is engineered for corrosive media shutoff in high-pressure, high-temperature systems. Built with a stainless steel body and PTFE disc, it resists aggressive chemicals and fluid breakdown. The electrically tripped, latched-open configuration ensures safe shutdown control in harsh process environments where reliability and manual reset are critical.
