Regin

ETVS - 2-way control valves, DN15-50, kvs 0.25-40, 20 mm stroke, DZR

2-way valves designed for control of cold, hot or glycol-mixed water, for use in DZR requirement systems (DZR = Dezincification 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. We also offer adapters for actuators of other brands.
