Product Description

The transmission thread of the gas gate valve is located inside the body, in the process of opening and closing, the valve stem only does rotating movement, and the gate is lifted in the valve body, so the height of the valve is small. Dark rod gate valve, usually installed above the valve cover opening and closing position indicator, in order to be suitable for ships, trenches and other small space and dust content of the environment.
Z942W-2 type gas gate valve features:
1, the bottom of the valve is provided with a sewage box, easy to clean dirt and impurities, and can be smoothly through the pipeline cleaner.
2, the valve stem adopts large guide program thread drive, which can realize fast opening and closing.
3, the use of friction power is minimal, can automatically lubricated, and resistant to gas and a variety of corrosive gas high-performance packing, flexible operation, reliable sealing.
4, excellent sealing performance, the operation can automatically eliminate the sealing surface dirt, keep a tight seal.
5, small fluid resistance. The medium channel inside the gate valve body is straight through, and the flow direction is not changed when the medium flows through the gate valve, so the flow resistance is small.
6, less effort to open and close. When opening and closing, the motion direction of the ram is perpendicular to the flow direction of the medium. Compared with the globe valve, the opening and closing of the gate valve is more labor-saving.
7, the medium flow direction is generally not limited. The medium can flow from either side of the gate valve in any direction, and can achieve the purpose of connecting or cutting off. Easy to install, suitable for the medium flow direction may change in the pipeline.
