12 Inch Valve

12 Inch Valve

12 inch valve is a joint of a water-used valve, which is essentially called a large diameter valve. Take the fire system as an example, the common civil buildings are basically the size of fire pipes below 12 inches. In the case of water companies and urban network systems, the water supply basically replaces the 12 inch gate valve with a 12-inch butterfly valve because the 12 inch gate valve is more expensive than the 12 inch one, and the butterfly valve opens for less time and has less space to install than the gate valve. Backflow preventers according to the present water supply network, especially drinking water pipeline backflow pollution is serious, and no effective device to prevent backflow pollution, developed a kind of strict limits on the water in the pipe can only be one-way flow of new type hydraulic control unit (backflow). In general, this valve applicable to clean water or physical and chemical properties similar to water and do not allow the backflow medium pipeline system.
