3-Way Solenoid Operated Valves (SOVs) are estimated to beÂ
85%Â of all instrument air SOVs in nuclear Applications
Â
| TYPICAL APPLICATIONS: |
| FUNCTIONS Normally Open (NO), Normally Closed(NC), or Universal (UNIV). SOV operation can be Direct Acting (Operates from 0-125 PSI) or Pilot Assist which is assisted by air line pressure within the system (35-150 PSI). BOILER WATER REACTOR In BWR design plants the AVCO SSPV(Scram Solenoid Pilot Valve) has an installed base of 4,000+ SSPV Since 1996; Depending on the generation BWR design; one Automatic Valve Corp. (AVCO) SSPV will replace two traditional SSPVs; more than doubling the qualified life & drastically reducing the amount of (Preventive Maintenance) PMs. SINGLE ACTING CYLINDER OR ROTARY ACTUATOR Three Way Solenoid Operated Valves (SOV) have three main ports (1) Line Pressure (2) Component Port (Operates the Component) (3) Exhaust port; Typically a 3Way SOV is used to alternatley apply pressure from the piston or diaphragm operator of a Control valve and/or Single Acting or Rotary actuator.
