Product Data Sheet
The VZ28 is a short stroke and small linear zone valve designed for control of hot and chilled water. The valve is used with a thermo-electric actuators type MZ14. 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. It is a BSP male threaded valves with flat face seals, a range of connection sets are available to mate onto pipe. Multipacks are not available. Two-way valve, Normally closed without actuator fitted. Pressure class PN16, stroke 2.5 mm. It is recommended to fit a strainer upstream of the valve to increase reliability and to follow water treatment guidelines as detailed in VDI 235. Valves should be installed in the return pipe to reduce exposure to media temperature extremes.
