2-way zone valve motorized

Categories: ,

This zone valve is equipped with a ball valve and an actuator. Is perfectly suited for district heating installations or stand-alone systems. The valve is completely pre-wired if preferred and fitted with a transformer. This allows a thermostat to be connected easily. Next to district heating systems the zone valve can be used in domestic installations where a house is divided into several comfort zones. Thanks to the high-pressure resistance and closing power this solution is not only simple but also very solid and safe.

 

Features

  • Divides an installation simply into multiple zones.
  • Completely pre-wired and equipped with transformer (optional)
  • Including a thermostat connection (optional)
  • Very easy to install thanks to the Snap-On mechanism of the actuator.
  • Approved by NUON district heating
  • Supplied with a ball valve
  • Very high differential pressure (Max. 280 kPa)
  • Settable Kvs value (0.5 – 8 m³/h)
