Control valve PN16
VLA300, VLB300
- Superb regulation for best mixing and flow regulating performance up to 16 bar (PN16).
- Real low internal leakrate and 100% tested product.
- Long lasting and high durability.
- Perfect match between the valve and ESBE actuators.
Series VLA-VLB are 2-way and 3-way control valves with flange connection PN16 and higher flow rates, suitable for mixing and flow regulation up to 16 bar. The valves are made of high-performing nodular iron allowing use in heating and cooling installations. The VLA-VLB series is available in 2-way DN15-DN150 ; 3-way DN15-150 and comes with one type of connection. The valve is perfectly combined with ESBE actuators and controllers.
