The YBS-20 automatic blowdown system monitors conductivity and temperature in steam-generator feedwater or returning condensate. When conductivity exceeds the setpoint, the discharge valve opens; it closes when conductivity returns below the configured limit.

The system helps control water quality and reduce unnecessary blowdown. The controller indicates blowdown status and provides a remote-monitoring output. Sensor chamber: 1 1/4-inch BSP, with conductivity sensor and sampling connection. Solenoid blowdown valve: up to 15 bar. Recommended accessories include a strainer, isolation valve and NK-16 sample cooler. Confirm the exact analogue-output range when ordering.
