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
