PRODUCT FEATURES
The ZVS range 2-port spring return valve has been designed for use with solar thermal systems, operating at a temperature of 120°C with short term peaks of up to 160°C. The internal components has been made of material suitable for use with both the glycol fluids used in solar systems and the high temperature experienced in normal operation.
The valves can be used in both heating and solar systems and can be used to zone off additional storage tanks, for heat dumping circuits, and to control or divert in place of pumps
Port A is normally closed when there is no power
