Structural characteristics of fluorine lined gate valve:

1. The valve body has two shapes: a flat body and a round body: GB valves use a round body, ANSI pound valves with DN ≤ 300Lb use a flat body, and DN ≥ 400Lb use a round body. The inner cavity of the valve body, valve cover, gate plate, outer surface of the valve stem and other parts that directly contact the medium are all lined with fluoroplastics such as FEP (F46);

2. The sealing pair is a combination of FPF (F46)/FEP (F46) or other materials, with low friction coefficient and low opening and closing torque;

3. The filler adopts PTFE (F4) standard filler, which has good sealing performance and is easy to repair and replace;

4. The elastic gate can compensate for the wedge angle deviation between the gate sealing surface and the valve seat sealing surface, with good fit and ideal sealing effect;

5. The medium can pass through the gate valve from any direction on both sides, suitable for acting as an opening and closing device on pipelines where the direction of the medium may change.
