Knife gate valves are often used in the mining of precious metal deposits, power supply systems in power plants, paper production systems, chemical materials systems, and food inspection systems. The knife gate valve has the advantage of being very compact and very tight due to the linear movement of the closing baffle (a plate that forms resistance to prevent fluid flow in the closed position). Knife gate valve is mainly composed of a shut-off valve, edge system, and structural system, although when the valve is in a partially open position, it can also be used as a control valve and well control the flow of fluid.

In addition to being used in the above environment, the knife gate valve can also be used in fluids containing solid particles, such as the more common wastewater or sludge cleaning systems. In general, in order to adapt to actual application requirements, knife gate valves are usually designed to be sealed on the upstream side of the circuit (that is, the fluid inlet side), but some valves do the opposite and are sealed on both sides, so no matter what kind of Knife gate valves can be used to achieve the purpose of flow control under working conditions and in the direction of fluid flow. In the open position, since the valve will not cause a change in the direction of the fluid, the head loss of the valve is very low. However, the closing and opening time may be very long, so this kind of valve also needs regular maintenance to correct the wear problem between the valve and the seal, which can also extend the service life of the valve.

Earlier, whether it was a knife gate valve or other valves, the resistance to complex and strict use environments was weak, and it was precisely because of environmental pollution that the service life was greatly shortened. The Shangzhou valve has undergone technical improvements, starting with the production of raw materials, and improving the valve’s performance. Corrosion resistance, in addition to avoiding physical and mechanical damage, the loss is relatively small during use, so the service life of the valve can be greatly extended under the premise of correct and compliant use.

While improving the service life of the valve, the fluid control capability of the knife gate valve has not been weakened, that is, Shangzhou Valve has not weakened the previous product advantages after improving the product performance. According to market surveys and user feedback, it is found that the product has a high praise rate and malfunctions. The rate has dropped significantly, which has further harvested long-term customers, and also enabled Shangzhou Valve to become a prominent position in the industry.

The important feature of the Shangzhou valve knife gate valve is the small space requirement in terms of thickness, and the low pressure head loss after technological innovation. Fluids containing particles are compatible, and further solves the problem of slow opening and closing. The business manager of Shangzhou Valve said: Because of the large number of knife gate valves used in many environments, maintenance has become a major pain point. Shangzhou Valve has passed products After optimization and innovation, the frequency of regular maintenance has been further reduced.
