High-temperature and high-pressure welded gate valve is suitable for Class150 ~ 3500Lb, operating temperature -29 ~ 570 ℃ petroleum, chemical, thermal power station and other conditions of the pipeline to cut off or connect the medium. Applicable media are: water, oil, steam and other non-corrosive media.
1. Product design and manufacture according to ASMEB16.34, E101 standard, can be equipped with imported equipment.
2. The valve adopts pressure self-tightening sealing structure in the middle chamber, the higher the pressure in the inner chamber, the better the sealing performance.
3. The two ends of the branch pipe are butt-welding connection, adapting to the different requirements of the receiver.
4. The sealing surfaces of valve flap and valve seat are made of stellite cobalt-based hard alloy, which is wear-resistant, high temperature-resistant, with good anti-scratch performance and long service life.
5. Valve cover packing box try to be reasonable, packing plus corrosion inhibitor, reliable sealing, smooth switching.
6. The valve has an upper sealing structure to ensure that the valve will not leak when the valve is open and running at the valve stem.
7. The opening and closing of the electric gate valve is controlled by the electric device, which is equipped with a special motor, reducer, torque control mechanism, on-site operating mechanism, manual and electric switching mechanism. In addition to local operation, it can also be operated from a distance.
