Three-Way Valve


Typical places of use

  • bypass regulation in the water/steam circuit
  • temperature regulation of steam by superheater bypassing


Basic technical data

  • Nominal pipe size: DN50 ... DN700 (2'' ... 28'')
  • Nominal pressure class: PN25 ... PN400 (ANSI class 150 ... 2500)
  • Temperature: up to 600 °C

 Main advantages

  • It realises the function of 2 control valves, reducing installation costs and requiring only one actuator
  • Defined leakage in the passage through a defined gap between the rotary segment and housing, thus ensuring a minimum flow through the closed connection
  • No vibration fractures, after positioning, the stem is free of forces and torques
  • Straight flow-through permits a permanent pressure loss < 0.1 bar whilst guaranteeing constant control performance
  • Optimal piping due to arrangement of the pipe axes in one plane
