Product Details

Product structure and working principle:


1. Using floating valve seat, two-way opening and closing, reliable sealing, flexible opening and closing;


2. The valve plate and valve seat are spray-welded with cemented carbide, which is resistant to wear and erosion;


3. The valve body has a high load-carrying capacity, and the passage is straight-through. When fully opened, it is similar to a straight pipe through the gate orifice, and the flow resistance is small. The valve stem adopts composite packing and multiple seals, which makes the seal reliable and low friction;


4. When closing the valve, turn the handwheel clockwise to move the valve plate down to the bottom. Due to the pressure of the medium, the seal seat at the inlet end is pushed toward the valve plate to form a larger seal specific pressure, thus forming the first seal , At the same time, press the gate to the outlet sealing valve seat to become a double seal;


5. Due to the double seal, the wearing parts can be replaced without affecting the pipeline work.


Z63Y High Pressure Flat Gate Valve-Product Description】


Model: Z43Y, Z63Y, Z83Y


The high-pressure flat gate valve has reasonable structure, reliable sealing and easy operation.

The sealing surface of the high-pressure flat gate valve is spray-welded with hard alloy, which has the advantages of corrosion resistance, wear resistance and erosion resistance, and can be used for throttling.

The high-pressure flat gate valve is especially suitable for water, oil, mud, and natural gas pipelines with a working pressure of ≤42MPa and a working temperature of ≤120℃ as an opening and closing and regulating device to control the flow of the medium.
