Mixing valve


  • Superb regulation for best bivalent performance.
  • The VRB240 has the same port configuration and flow pattern as the old valve series BIV
  • Compact, flexible and easy to install.
  • Long lasting and high durability.
  • Perfect match between the valve and ESBE actuators.

Series VRB240 are 4-way valves suitable for bivalent operations. The difference from VRB140 is the ports orientation. 
The valve is made of high performing brass, allowing use in heating and cooling installations. The VRB240 series is available in DN20 and comes with compression fitting type of connection. The valve is perfectly combined with ESBE actuators and controllers.
