The dynamic differential pressure balancing component can ensure that the pressure difference before and after spool adjustment is stable. Within the operating differential pressure range, the flow value of valves is stable within its error range, and will not change due to pressure variations of the water system. This effectively improves the flow stability of valves and strengthens the output air temperature stability of air handling units, achieving comfort and energy saving. The maximum flow setting component enables the maximum flow to be set according to the required flow value of the controlled air handling unit, eliminating overflow and underflow phenomena in terminal branches, achieving static balance of terminal devices. VAFC series dynamic differential pressure balancing electric switch valves are turned on/off with thermoelectric actuators, which feature a slow on-off speed to avoid water hammers.
Features & Benefits:- Built-in dynamic differential pressure balancing assembly
- High shut-off differential pressure and low leak rate
- Manual and quick setting of the maximum flow on site
- Valve kept normally open when not installed with its actuator, facilitating initial pipeline flushing and commissioning
- Noise-free operation and long service life
- Easy assembly of actuators and valves
