Product Description

Non-Rising Stem Manual knife gate valve is a kind of knife gate valve. Its structural feature is that the stem and gate are driven in parallel on different sides, so the Non-Rising Stem valve can save 50% of the space compared with the Rising Stem valve.It has the advantages of light weight, simple structure, reliable sealing, long service life, and effective cutting of fibers in the medium.The sealing principle is that when the gate is closed to the bottom, the chamfered surface of the gate touches the wedge on the valve body to make the gate close to the sealing surface to achieve a sealing effect, and the chamfered surface at the bottom of the gate has the function of cutting off the medium, so that The valve is not easy to be blocked by debris, and it can also scrape off the adhesion on the sealing surface and automatically remove the debris. The stainless steel gate can prevent the seal leakage caused by corrosion.It is suitable for fluids that are difficult to control, such as slurry, powder, and fiber, and is widely used in papermaking, petroleum, chemical, drainage, food and other industries.
