The VZ308E 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. The valve is BSP male threaded valves with flat face seals, a range of connection sets are available to mate onto pipe. Size DN 20, G3/4A connection, 6 Kvs. Pressure class PN16, stroke 2.5 mm, Normally closed (A-Ab). External thread to ISO 228/1 (flat face seal).
