Control valve PN6

VLF100

  • Superb regulation for best mixing and flow regulating performance up to 6 bar (PN6).
  • Real low internal leakrate and 100% tested product.
  • Long lasting and high durability.
  • Perfect match between the valve and ESBE actuators.

Series VLF are 2-way and 3-way control valves with flange connection PN6, suitable for mixing and flow regulation up to 6 bar. The valves are made of high-performing nodular iron allowing use in heating and cooling installations. The VLF series is available in 2-way DN20-DN50 ; 3-way DN20-DN50 and comes with a PN6 flange to suit PN6 flange pipe connections. The valve is perfectly combined with ESBE actuators and controllers.
