  Kv = water flow in m³/h with pressure drop of 1 bar (1 bar = 100kPa).

• 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-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.
