Gate valve 12 inch is a common valve size in pipelines.
The valve body of ZECO 12 inch gate valve is straight through the structure, which is similar to the straight pipe in the fully open state, to ensure the minimum flow resistance and swirling flow, and reduce the cost on the user’s pipeline. There are two ways to connect the valve body and bonnet, one is the bolt connection of valve body bonnet, the other is the pressure self-sealing structure, the interior of the valve body of both kinds of structure is the same, there is a guide rail to allow the gate fixed movement, not caused by deviation from the impact of sealing problems. Bonnet and bracket are integral and split, depending on the size of the gate valve, usually 10 “or less is one piece only bonnet & yoke and 10” or more is bonnet yoke split.
12 inch Gate valves can be found anywhere an economical shut off is required. Gate valves are ideal for any application that involves slurries as the gate can cut right through. Gate valves are also common in applications using liquids like heavy oils, light grease, varnish and other non-flammable liquids.
