The Asco 8210G035VH Solenoid Valve is a normally open, pilot-operated valve designed for high vacuum breaker and suction or release applications. Its high-vacuum construction ensures minimal leakage, making it ideal for systems requiring precise pressure equalization and controlled vacuum release. With de-gassed and cleaned elastomers, it provides reliable operation in roughing pumps and other vacuum-dependent equipment.
For general-purpose valves, see Asco 8210G035.
