Regin
MTVS20-4,2 MTVS, MTRS - 2- and 3-way control valves, DN15-50, kvs 0.63-39, 20 mm stroke, DZR
Valves designed for control of hot, cold or glycol-mixed water in heating and ventilation systems. They also function very well where DZR-material is a requirement (DZR = Dezincification Resistant). The valves are intended for use together with Regin’s RVAN5 actuators. RVAN10 actuators can also be used if larger actuating force is required.
