Features
- The KAR5 is a combination kinetic air release valve with an integral adjustable anti-shock mechanism
- During pipeline filling, the large kinetic orifice vents bulk air at high flow rates
- Once the pipeline is pressurised, the small orifice continuously releases accumulated air pockets
- On rapid pump shutdown or column separation, the anti-shock needle valve limits the rate of water re-entry to protect against surge-induced pressure transients
- The closing rate is field-adjustable without special tools
Description
Adjustable anti-shock protection for potable water mains. The KAR5 is a combination kinetic air release valve with an integral adjustable anti-shock mechanism. During pipeline filling, the large kinetic orifice vents bulk air at high flow rates. Once the pipeline is pressurised, the small orifice continuously releases accumulated air pockets. On rapid pump shutdown or column separation, the anti-shock needle valve limits the rate of water re-entry to protect against surge-induced pressure transients. The closing rate is field-adjustable without special tools.
