Details
Product Overview: This device can release pressure exceeding the pilot valve's safety setpoint in the water pipe, while maintaining the system pressure below a safe threshold to prevent damage to pipeline equipment caused by high or sudden pressure surges.
It can be used in the fire circulation system of high-rise buildings to relieve pressure, preventing excessive water pressure that could pose a safety risk to the system. Pressure-holding valve: This device maintains the water supply pressure upstream of the main valve at or above a preset level, ensuring adequate pressure in the upstream section.
Emergency check valve: Installed at the outlet of the fire sprinkler pump, it opens immediately when the pressure at the pump outlet exceeds a preset threshold.
Superior cavitation resistance: The valve employs collision-based energy dissipation, and its unique cage structure ensures safe operation even under extreme cavitation conditions—without any minimum cavitation index limitations.
