Product Description:

Wedge gate valve is the most common type of opening and closing valve, which uses wedge-shaped gate plates sealed on both sides to connect or disconnect the management circuit. Wedge gate valves are not allowed to be used as throttling devices in pipelines with slight opening, in order to avoid accelerated sealing damage caused by erosion of high-speed flowing media.

1、 Characteristics of Wedge Gate Valve
1. The valve body has two shapes: flat body and round body: GB valves use round body, ANSI pound class valves DN ≤ 300LB use flat body, and DN ≥ 400LB use round body. The inner cavity of the valve cover, gate plate, and outer surface of the valve stem, which are in direct contact with the medium, are all lined with fluoroplastics such as FEP (F46) or PCTFE (F3);
2. The sealing pair is composed of FPE/FEP (F46) or other materials, with a low friction coefficient and low opening and closing torque;
3. The packing adopts PTFE (F4) standard packing, with good sealing performance and easy maintenance and replacement;
4. The valve plate with elasticity can compensate for the wedge angle deviation between the gate seal and the valve seat cover, with good fit and ideal sealing effect.

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