Regin

ETRS40-20 ETRS - 3-way control valves DN15-50, kvs 0.63-40, 20 mm stroke, DZR

Valves intended for control of cold, hot and glycol-mixed water in heating, ventilation and when DZR material is a requirement (DZR = Dezincification Resistant). The valves are intended to be used together with Regin’s RVAN5 actuators. RVAN10 actuators can also be used if larger actuating force is required. The valve is supplied with a cover lid for converting the 3-way valve into a 2-way valve.
