Scram Solenoid Pilot Valve
The Scram Solenoid Pilot Valves (SSPVs) are an integral part of the BWR reactor protection system.
SSPV type 2562 was designed to original specifications and fits into the existing mounting configuration of the BWR Hydraulic Control Unit with no hardware modification needed.
- Proven design with no reported malfunctions since initial installation in 2000
- Reliable, short switching times
- Low power consumption reduced aging
- No membranes
Seitz provides spare parts, replacement solenoids and maintenance services for the SSPVs.
