The Electro-pneumatic Valve has been designed to satisfy a wide range of requirements.

Using the compressed air provided by the user, the Electro-pneumatic valve puts into communication alternatively the two outlet lines with the valve’s single inlet line where the lubricant is in pressure.

The solenoid valve is therefore activated (and powered) directly by the electrical equipments that control the system. In this way it automatically controls the lubrication cycle.


*  Dual Line: inversion of Dual line systems.

* Progressive and zoned systems: by plugging port 1 or 2. The valve can be used for zone complex circuits.

* Grease applications: particularly suited for grease, it can be applied to any circuit requiring a 4/2 valve.
