Z63Y Butt welded high-pressure flat gate valveDetailed product description：

Structural characteristics and working principle of Z63Y butt welded high-pressure flat gate valve
1. Adopting a floating valve seat, bidirectional opening and closing, reliable sealing, and flexible opening and closing.
2. The lower part of the gate is equipped with a guide hole and provides precise guidance. At the same time, the sealing part is sprayed with hard alloy for erosion resistance.
3. The valve body has high load-bearing capacity, and the channel is straight through. When fully opened, it is connected to the gate guide hole and is similar to a straight pipe, with very low flow resistance. Composite packing is used at the valve stem, with multiple seals to ensure reliable sealing and low friction.
4. When closing the valve, turn the handwheel clockwise and the gate will move down to the bottom. Due to
The action of mass pressure pushes the inlet seal seat towards the gate direction. Create a larger sealing pressure ratio, thus forming the first seal. At the same time, press the gate onto the sealing seat at the outlet end to form a double seal.
5. Due to the use of double sealing, vulnerable parts can be replaced without affecting the operation of the pipeline. This is an important feature that sets our factory's products ahead of similar products both domestically and internationally.
6. When opening the gate, rotate the handwheel counterclockwise to move the gate up and connect the guide hole with the channel hole. As the gate rises, the through hole gradually increases. When it reaches the limit position, the diversion hole coincides with the channel hole and is fully opened.
