L’électrovanne se compose d’une membrane qui actionne le passage du flux principal et d’un piston qui commande le circuit secondaire d’assistance à la fermeture.
Pour la version NF (std) :
On utilise la pression amont comme contre pression pour actionner la membrane à la fermeture du circuit principal.
Le piston soulevé lors de l’alimentation de la bobine libère la contre pression commandant ainsi l’ouverture du circuit.
Ce type d’électrovanne doit toujours être installé sur une canalisation sous pression, avec une ΔP de minimum 0,3 bar.

Electrically actuated 2-way ball valves are useful to stop the flow of fluids in part of a plant. Opened, they do not induce pressure drop. Closing time is about 10 seconds. These models in plastics are designed for aggressive liquids. Assistance with manual operating for maintenance or emergency operations (actuator power supply is switched off before a manual operating).

Electrically actuated 3-way ball valves are useful for redirecting or to stop the flow of fluids in plants. These models in plastics are designed for aggressive liquids. Assistance with manual operating for maintenance or emergency operations (actuator power supply is switched off before a manual operating).

The 2-way ball valves, type S4, are designed for industrial and chemical applications with various materials combination. Ball seat seals made of PTFE allow a long operating time. A safety and locking handle for a non-accidental operation.

Pneumatically actuated 2-way ball valves are designed to allow / stop the flow of liquids, even chemically aggressive. The options permit automatic operations.
