Installation Locations:
●At pump discharge outlets.
●Along water transmission and conveyance pipelines.
Primary Functions:
●Prevents water hammer, surge, and pressure shock phenomena.
●Protects pumps and pipeline systems.
Operating Characteristics:
●Pump start-up: The valve disc opens automatically.
●Pump shutdown: The valve disc first closes rapidly to approximately 90%,
then closes slowly through a pneumatic/hydraulic damping system.
▶effectively suppressing water hammer.
System Advantages:
●Extends the service life of pipelines and equipment.
●Suitable for high-head pumping or large-flow water conveyance systems.
●The pneumatic–hydraulic damping system allows the main valve to close gradually,
preventing the occurrence of water hammer.
