STEEL KNIFE GATE VALVE
Steel knife gate valve is widely used in industry. The valve body is made of high carbon steel and the valve disc is made of forged steel. The precision machined parts ensure that the sealing face has excellent deburring, roughness and cleanliness, is not easy to wear, and the sealing performance can be maintained at a high level. Steel knife gate valve is non closing and non-rotating valve element. It consists of a cylinder with a circular flange at one end, in which a completely flat piston can move freely within the diameter of the valve core body.
Product introduction:
Steel knife gate valve is a general gate valve widely used in industry. The valve body is made of high carbon steel and the valve disc is made of forged steel. The precision machined parts ensure that the sealing face has excellent deburring, roughness and cleanliness, is not easy to wear, and the sealing performance can be maintained at a high level. Steel knife gate valve is a non closing and non rotating valve element. It consists of a cylinder with a circular flange at one end, in which a completely flat piston can move freely within the diameter of the valve core body. The other end of the gate valve is equipped with a gasket seat and a disc blocking device made of special hardening materials. Therefore, when the disc (blocking device) rotates under force, it presses on the inner surface of the valve chamber to prevent or open the fluid flow in the valve.
Steel knife gate valve is manufactured with the latest technology. The provided valve is placed in the pipe so that it can provide a flow path for the fluid to pass through it. The materials and other components used to manufacture this valve are of high quality, which can maintain a long service life and have the possibility of zero leakage. In addition, we also provide various specifications of this steel knife gate valve at reasonable prices.
Product advantages:
our knife gate valve is made of high-quality materials. 2. our valve design conforms to national standards, so we can make any necessary connection between pipelines, whether in terms of diameter or section. 3. the gate type design makes it easy for operators to open and close the valve, which is equivalent to the best operating performance.
Steel knife gate valves are often used as isolation methods for pipelines, process facilities and ports. Knife gate valves are an excellent solution for isolating an area from piping or vessels during maintenance, repair, or other work activities. Knife gate valves are designed for positive shutoff, air tight shutoff, and operation above standard valve operating pressure in most applications.
Product design:
Steel knife gate valves are designed to handle large flows and pressure drops in a wide range of process and general industrial applications. These valves are equipped with sealing rings made of materials that can withstand the most severe environmental conditions, such as high temperature, erosion, corrosion, wear and freezing. The exquisite design has smooth, perfect matching and easy operation. Two different sizes of valve body and rectangular flange not only ensure that it can be assembled into units of various sizes, but also make the price reach a very competitive level.
Knife gate valve is a low-pressure, positive acting gate valve with excellent flow characteristics and minimum pressure drop in both directions. Its sealing design makes it easy to disassemble for cleaning, maintenance or inspection. The valve is compact in size, light in weight and high in strength. It is an ideal choice for fixed service. In this case, it is most important to achieve high reliability at the lowest possible life cycle cost.
