VFD2, 2-Way Control Valves with Internally Thread Union Connection, DN15–50

2 way valves, DN15-50, kvs 0.25-40, 20 mm stroke. Designed for control of cold, hot or glycol-mixed water. For use in domestic water systems or district heating within the temperature range -5°C...+150°C. 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 RVAN5 actuators.
