CASTEL

Pressure control valve for water
CASTEL

pressure outside the bellows favours the opening of the valve and the thrust of the adjustment spring on the shutter acts in the opposite sense. Given a specific setting of the spring, the valve progressively opens in line
with the increasing condensation pressure, and closes when this pressure decreases. When the compressor stops, the valve closes: water is no longer fed into the condenser, this being a notable operating economy.
Valve setting is performed in the works at a pressure of 7,5 bars. Setting is modified by turning the control screw.
