Solenoid Valves series 14-E

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:

• open the piston and keep it lifted off the main opening
• close the piston and ensure the tightness on the main opening

Basic specifications
