Castel presents a preview of its new 14-E Solenoid Valve series for transcritical and subcritical CO2 systems with a maximum operating pressure of up to 140bar.
The solenoid valves are normally closed valves (NC).
All the valves are exclusively sold in the model without coil (suffix S). These valves can be coupled with the coils in series 9320.
The valves in series 14-E are pilot-operated piston solenoid valves. Their operation depends not only on the magnetic field produced by the current flow into the coil, but also on a minimum inlet pressure, which is necessary to:
