BTV20-1,6 BTV - 2-way control valves, DN15-50, kvs 0.6-39, 20 mm stroke

The valves are designed for control of hot, cold or glycol-mixed water in heating and ventilation systems. They are pressure balanced (from DN20-50, not DN15) and can therefore handle high differential pressure with low force. The valves are intended to be used together with Regin’s RVAN5 actuators. They should not be used in domestic water systems.
