Both AWWA ductile iron body flanged gate valve and DIN ductile iron body flanged gate valve can be metal seated and resilient seated
For AWWA ductile iron body gate valve pressure can be Class125/150, PN10/16,5K/10K/16K. For DIN ductile iron body gate valve pressure can be PN10/16.
Standard: AWWA C509, AWWA C515
Facing: RF,FF,RTJ
AWWA Ductile Iron Body Flanged Gate Valve is suitable for connecting in American standard pipe system, DIN standard for DIN standard; But there is no difference in gate valve installation
A gate valve consists of a valve body, seat and disc, a spindle, gland, and a wheel for operating the valve. It is the most common valve for the piping system.
No, gate valves are generally used to shut off the fluid flow, they are used either in the fully closed or fully open positions.
