REGIN -way valves designed for control of cold, hot or glycol-mixed water, for use in DZR requirement systems (DZR = Dezincifi cation Resistant) 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 Regin’s RVAN5 actuators.
