HOMOLOGATION AND INSTALLATION
Homologation
- EN 60335-1:2013 + A11:2015
Installation and use- Female threaded connection from G 3/8 to G 2.
- The valves can be installed in any position.
- 2-way execution, normally-open.
- Indirect operation with blocked servo-membrane.
- The fluid under pressure before the valve passes freely above and below the diaphragm, in the passage orifice of the valve and in the
pilot plug orifice. - When the coil is energized, the pilot plug closes and the fluid under pressure before the valve enters the space above the membrane,
pressing it against the seat, blocking the passage. - N.B. Minimum operation pressure between the upper and lower limit should be 0,1 bar.
