The VZ308C is a small linear three-way zone valve used for the control of hot or chilled water in terminal units. It is designed to be used with the MZ140 family of thermal actuators. The valves utilise a double O-ring design on the plug to ensure a leak tight seal on both valve ports, this ensures no loss of energy leakage through the valve. 15mm Compression connection Three-way valve, Normally closed (A-AB) without actuator fitted. DN15, Kvs: 0.25 m³/h. Pressure class PN16, stroke 2.5 mm, Normally closed (A-Ab). It is recommended to fit a strainer upstream of the valve to increase reliability and to follow water treatment guidelines as detailed in VDI 2035. Valves should be installed in the return pipe to reduce exposure to media temperature extremes.
