The VZ219C is a short stroke and small linear zone valve designed for control of hot and chilled water. It is designed to be used with the MZ200 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. 15mm Compression connection Two-way valve, Normally closed without actuator fitted. DN15, Kvs: 0.6 m³/h. Pressure class PN16, stroke 5.5 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.
