Class：HVAC Products
----------------------------------------
Application
The Series W-DPA942 Pressure Independent Control
Valveis designed for terminal equipment in AHU, PAU or
MAU systems and for terminal equipment such as plate heat
exchanger in heating systems. It is used to regulate the flow
and simultaneously keep the differential pressure at both ends
of the valve constant. Since the valve avoids flow fluctuation
caused by the opening or closing of other equipment, the
system is able to be stable, efficient and energy-saving.
Features
- Equal percentage flow characteristic
- Constant differential pressure is achieved
- Self-balancing valve core realizes easy shutoff
- V-ring sealing and self-compensating spring result in higher
abrasion resistance and longer service life
- Electronic preset of maximum flow facilitates on-site
commissioning
- Fault auto-detection and alarm function
- Overload protection for power supply
- Stroke auto-detection
- Manual lever for convenient on-siting commissioning and
troubleshooting
