Advantages

1. All valve bodies are precision cast valve bodies, with WCB-compliant materials, fine appearance, no sand holes, and furnace number marks on each batch of castings, which facilitates production tracking and ensures material inspection

2. The valve body is made of ZG250-485 material that meets national standards. It undergoes 15 processes from raw iron to valve body molding.

3. The butterfly plate is processed by CNC lathe, and the sealing ring is a soft and hard multi-layer stacked metal ring, which has the dual advantages of metal and elastic sealing, ensuring excellent sealing performance in high and low temperature environments

4. The valve stem is made of stainless steel, and the strength of the valve stem is doubled after quenching and tempering, reducing the opening and closing and leakage problems caused by valve stem deformation

5. After the product is produced, each product is painted three times with lead-free paint for primer and topcoat to ensure the brightness and corrosion resistance of the product appearance

6. After the product is pressed and debugged, the turbine adjustment screw is processed again, and the left and right lengths are adjusted to be consistent before shipment. The turbine adjustment screw of each product is equipped with a protective nut to protect the adjustment screw from damage

7. The valve plate is thick, the valve stem is thick, the pin is thick, and the valve seat is finely processed, flat, and has no welding scars.

8. Quality inspection at every link from the rough to the finished product packaging and factory delivery
