The EFLS series indirectly operated solenoid valves are two-way, two-position diaphragm solenoid valves.

This allows for very large passage holes, thus handling significant fluid flow rates.

Electrically operated by a pilot solenoid, due to their internal structure, there is a minimum operating pressure and a delay in the opening and closing phase, which, for versions from G1 1/4 to G2, can be adjusted using the appropriate screw located on the brass body.

They are available in two monostable types (normally open and normally closed) with 5 passage holes and sizes from G3/8 to G2.

In the normally closed version, they are supplied with a manual control button.
