KOSO 600B Butterfly Valves Casting Body Type

KOSO 600B Butterfly Valves/Casting Body type Metal seal ring with a cut-end is set around the disc. KOSO 600B Butterfly Valves/Casting Body type realizes low seating force and better shut-off performance. It also provides more resistance against very high operating temperatures. The seat ring’s thermal expansion with fluid temperature fluctuation makes the valve best suited to high-temperature fluid service.

Product Features

KOSO 600B Butterfly Valves/Casting Body type is a wafer type butterfly valve, designed to be inserted between the pipeline flanges for connection. As an economical valve to control liquids or gases of relatively low pressure, it is available up to a large diameter. This compact and lightweight valve can be used for fluids containing floating particles as well.

Butterfly valve, also called flap valve, is a simple regulating valve that can be used for on-off control of low-pressure pipeline media. The butterfly valve opening and closing part is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media. It mainly plays the role of cutting off and throttling on the pipeline. The butterfly valve is not only simple in structure, small in size, light in weight, low in material consumption, small in installation size, small in driving torque, simple and rapid in operation, but also has good flow regulation and closing and sealing characteristics at the same time. The use of butterfly valves is very extensive. The variety and number of its use continue to expand, and it is developing towards high temperature, high pressure, large diameter, high sealing performance, long life, excellent adjustment characteristics, and one valve with multiple functions. Its reliability and other performance indicators have reached a high level.
