Product parameters

JIS 10K Japanese standard double clamp butterfly valve JIS 10K butterfly valve is divided into 10K and 20K, and its main structural feature is the double clamp triple eccentric metal hard seal. The valve seat sealing ring adopts two structures: elastic sealing and multi-layer sealing with soft hard compatibility. Its sealing performance is reliable, ensuring that the butterfly plate does not contact the sealing seat when opened, eliminating uneven sealing load and extending service life, ensuring reliable sealing performance, and having advantages such as high temperature resistance, wear resistance, and corrosion resistance. Widely used in petroleum, chemical and industrial environmental water treatment, high-rise buildings, water supply and drainage pipelines.

Butterfly Valve FAQs

01 Which butterfly valve seat design should be used?
Common designs include resilient seats and metal seats. Resilient-seated valves are generally used for water, air and low-leakage services at moderate temperatures. Metal-seated valves are selected for higher temperature, pressure or erosive industrial media. The final choice depends on the medium, temperature, pressure and required leakage class.
02 How do wafer, flanged and lug butterfly valves differ?
Wafer valves are compact and require little installation space. Flanged valves provide a stable pipeline connection for larger sizes or higher pipe loads. Lug valves can facilitate one-sided removal and maintenance. Selection depends on the piping standard, space, size and maintenance method.
03 Should a butterfly valve use pneumatic, electric or manual actuation?
Manual or gearbox operation suits local isolation. Pneumatic actuators provide fast response for frequent operation and hazardous areas. Electric actuators support remote control and modulation. The actuator must be sized for valve size, differential pressure, torque and control signal.
04 Which operating data are required for butterfly valve selection?
Provide the medium, design temperature, design pressure, nominal size, connection standard, body and seat materials, leakage class, flow direction, operating frequency, actuation method and any enclosure or explosion-protection requirements.
