Kv = water flow in m^3/h with pressure drop of 1 bar (1 bar = 100kPa).
INSTALLATION
Female threaded connection from G 3/8 to G 2.
The valves can be installed in any position.
OPERATION
2-way execution, normally-closed.
Indirect operation with blocked servo-membrane.
The fluid under pressure before the valve enters the space above the membrane, pressing it against the seat, blocking the passage. When the coil is energized, the pilot plug opens discharging the flow, therefore the media lifts the membrane disc, opening passage orifice of the fluid.
