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
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.
Selection notes
This air release valve is supplied for flanged installation.
Sizes run DN50 to DN300, in PN10, PN16, PN25, ANSI 150.
The body is EN-GJS-500-7.
Seat and trim options are EPDM. The seat, not the body, usually sets the temperature and medium limit, so confirm it against the service before ordering.
Stated service media include clean water.
It is catalogued for Water & Wastewater.
Working temperature is -10°C to 80°C.
Built to BS EN 1074-4, AWWA C512, BS EN 1092 and ANSI B16.5.
