1. The
Gate Valve adopts flange bolt connection, and the two ends of the branch pipe are flange connection structures.
2. The sealing surface of the Gate Valve seat is made of iron-based chromium-nickel stainless steel surfacing, which has good wear resistance and abrasion resistance.
3. The surface of the Gate
Valve Stem is treated with corrosion resistance nitriding, which has good corrosion resistance and abrasion resistance.
4. The closing and opening of the
Universal Valve are controlled by the electric device installed on the valve cover. The electric device is equipped with a special motor for Universal Valve, a reduction box, a torque control mechanism, a stroke control mechanism, a field operation mechanism, and a manual and electric switching mechanism. The opening and closing of the Universal Valve are adjusted by the stroke control mechanism. Adjusting the torque limiting mechanism can protect the Universal Valve in the event of failure of the stroke control mechanism. The closing of the Universal Valve is mainly composed of an electric device and adjustable wedge-type double gate plates, universal tops, clamping rings, etc., and the valve body is guided to perform lifting and lowering movements.
5. In addition to local operation, the electric device can also be operated remotely.
