V70900-98 Air Pilot Operated Solenoid Valve

V70900-98 solenoid valve


Valcor Nuclear has created this compact size and low weight 3-way, direct-acting, nuclear-qualified solenoid valve, to be used primarily as an air pilot control valve in nuclear power plants. It has been designed specifically to prevent the chronic operational problems associated with conventional solenoid valves currently installed in many PWR, BWR and CANDU plants. Valcor Model 70900-98 is ideal for use in host of safety-related, low flow solenoid valve applications. It’s cool running, single coil design is both highly reliable and adaptable, offering significant improvements for a variety of applications. The versatility of Valcor’s 70900-98 valve allows for a variety of configurations, including 2-way (one port plugged), normally closed, normally open and universal modes, with AC or DC voltages.
