MAIN FEATURES:
The two sealing faces of a slab gate valve are perpendicular to the pipeline axis, its closing member is a single disc, valve equipped with a stretching mechanism. The gate valve is widely applicable for transmission pipeline system of natural gas 、oil products and chemical engineering.

From the aspect of structure style, the through conduit gate valve can be divided into two types of valves with diversion holes and valves without any diversion hole.

Design Features
Design standard as per: API 6D、ASME B16.34、GB/T 19672
The valve disc and valve seat seal are repeatedly treated by special processes, and protected by multiple seals, and featured with anti-corrosion, penetration-proof, anti-abrasion and long service life;
Valve seat is designed with hard-soft double seal, having reliable tightness;
With a full bore design, both the coefficient of flow resistance and the pressure loss are very small;
When the valve is fully opened, medium erosion occurring to its sealing face is smaller than that of other valves;
The through conduit gate valve with diversion holes installed on a pipeline can also be cleaned by a pipe cleaner directly;
For adjustment structure, the valve have a good flow adjusting ability;
No space restriction on valve installation, that is, both parallel and perpendicular installations are allowed.
