Description
The VZ319E is a small linear three-way zone valve used for the fine control of hot or chilled water in terminal units. It is designed to be used with the MZ20 family of electro-mechanical actuators, these actuators are available in 3 point floating and modulating control. The valve 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 5.5mm stroke length coupled with the high resolution MZ20 electro-mechanical actuator provides good hydronic control. The valve is male threaded valves with flat face seals, a range of connection sets are available to mate onto pipe. Size DN 15, G1/2A connection, 0.25 Kvs. Pressure class PN16, stroke 5.5 mm, Normally closed (A-Ab). External thread to ISO 228/1 (flat face seal).
