ZTV / ZTR - 2- and 3-way control valves DN15-25, kvs 0.25-7.0, 5.5 mm stroke

Valves used for control of hot and cold water in climate, heating and ventilation systems. They can also control glycol-mixed water in for example liquid connected recovery systems. Intended to be used together with the RVAZ4 actuators.
