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 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 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.
