Valve:

Material:
  • Housing: Forged brass ASTM CuZn40Pb2 or DZR ASTM CuZn36Pb2As
  • Ball valve: ABV: Chemically nickel-plated brass ball
    End Connections²:
    A: Fixed female ISO or NPT
    AB: Fixed female ISO or NPT
    ABV: Union end connections in brass alloy ISO or NPT
    Housing taps: AB/ABV: 1/4” ISO
Note 1: Stated temperature rating is defined due to no external spindle condensation.
Note 2: NPT only available ex. US-factory.

The standard actuators available for the FlowCon EVS valve are thermal actuators that operate ON/OFF on 24V AC/DC, 120V AC and 230V AC or modulating on 24V AC respectively. ON/OFF actuators are available with end switches which can be used for controlling the fan in priority to the open position of the valve.

The EVS-insert with stainless steel insert will in connection with the FlowCon A, AB and ABV1 valve housings provide temperature control and dynamic balancing for use in cooling ceilings, fan coil units in air-condition or as zone valve in heating systems.
