ZTVB / ZTRB - 2- and 3-way control valves, DN25-40, kvs 8-20, 5.5 mm stroke

Valves for control of heating and cooling in climate, heating and ventilation systems. They can also control glycol-mixed water in for example liquid recovery systems. The valves are intended to be used together with the RVAZ4 actuators. A hand wheel for manual operation is delivered with the valve.
