Solenoid Valves IMI Herion Solenoid Valves are used to control different applications within many VVER’s (pressurised light water cooled reactors) around the world since the early 1970’s. They are typically used on various ball / globe / gate – valve assemblies operated by high pressure actuators (from globally recognised manufacturers). These actuators require IMI Herion Pilot Operated Solenoid Valves, to ensure safety on water and steam circuits.

Process Valves Process Solenoid Valves are applied in different applications across diagnostic and measurement systems. One of the most extended applications is the radiation monitoring system where the valves are used as Isolation Safety Shut-off Valves. Solenoid valves provide an added advantage by its natural position – “normally closed” – which means that when the coil is de-energised, the valve is closed for quick fluid isolation. Most process solenoid valves are equipped with open / closed position indicators. These valves are offered with end-connections to a wide range of specifications.
