How energy efficiency is improved
Reliable actuation in efficient control systems
- Regulating valve free of silicone grease with male thread (DIN EN ISO 228-1) for cold and hot water in closed and open circuits
- In combination with valve actuators AVM 105(S), 115(S), 321(S) and AVF 124, 125S as a control unit
- Equal-percentage (F300) / linear (F200) characteristic, can be set with SUT valve actuators (SAUTER Universal Technology)
- The valve is closed when the spindle is moved out
- Can be used as a control valve or a distribution valve
- Stainless-steel spindle
- Valve body with valve seat made from dezincification-resistant cast brass (DZR)
- Plug with glass-fibre-reinforced PTFE sealing ring made from dezincification-resistant cast brass (DZR)
- Stuffing box with wiper ring made from dezincification-resistant cast brass (DZR) and double O-ring seal made from EPDM
