The Asco 8030G017VH Solenoid Valve (8030G17) is a direct-acting, normally closed valve for high-vacuum service. With vacuum-hardened elastomers and a 16.1-watt Class F coil, it operates at zero pressure differential. Ideal for electrical check, breaker, roughing, suction, or release in vacuum systems used in process tools, analytical chambers, and controlled evacuation lines.
