These valves are 1 inch gas-operated full-port ball valves incorporating a solenoid and limit switches as integral parts of the actuator that are used in process streams within the CWF hood. The valves fail closed (on loss of pressure or electrical) to prevent MCO vent drain to either reduce air In-leakage or loss of He. The valves have couplings for transverse actuator mounting
