How energy efficiency is improved
Efficiency means precise changeover with minimum leakage
- 3-way change-over ball valve with T-bore for use in closed circuits in heating, ventilation and air conditioning systems
- For changing over volume flows in combination with valve actuators AKM 105(S), 115(S) and AKF112, 113(S).
- Fast changeover in 6 s with valve actuator AKM115SF152
- Low torque due to collar mounted on O-ring
- Spindle with friction ring and double O-ring seal
- Ball valve with female thread as per ISO 7/1 Rp
- Body made of dezincification-resistant cast brass
- Ball made of dezincification-resistant brass, chrome-plated and polished surface
- Strainer and screw fitting available as accessories
- Water quality as per VDI2035
- French drinking water approval ACS
