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.
1. ZECO technical engineers have fully considered the difficulty of after-sales service, so they developed the structure that can be maintained online, such as renewable valve seat, online replaceable packing, online replaceable hand wheel, etc., so as to facilitate the maintenance of after-sales personnel;
2. The wedge of ZECO 12 inch gate valve is ground to a mirror surface before assembly to ensure that it fits tightly with the seat ring and does not get stuck;
3. The valve stem sealing of ZECO 12 inch gate valve is realized by the collaboration of flexible and woven graphite, ensuring a more reliable tightness;
4. ZECO 12 inch gate valve has a good sealing performance at high temperature, and a wedge valve is not easy to jam after heating. Suitable for steam, high-temperature oil, oil, gas, and other media, as well as frequent switching components.Not suitable for easily coking media.
