JIS 10K butterfly valve is divided into 10K and 20K. The main structural feature is the wafer-type triple eccentric seal. The seat seal ring adopts two structures: elastic seal and multi-layer seal compatible with soft and hard. Its sealing performance is reliable, ensuring that the butterfly plate does not touch the seal seat when it is opened, eliminating the need for seal Uneven load prolongs the service life, ensures reliable sealing performance, and has the advantages of high temperature resistance, wear resistance, and corrosion resistance. Widely used in petroleum, chemical and industrial environmental protection water treatment, high-rise buildings, water supply and drainage and other pipelines.
Frequently Asked Questions
How do I make sure my order is for the JIS 10K wafer version?
Identify the required pressure designation, valve size and mating flange details in the inquiry and ask for them to be confirmed on the quotation and drawing. The wider series discussion does not replace the exact order specification.
What should I confirm about the metal or multilayer seat?
Request the selected seat construction and materials and provide the actual process conditions and shutoff requirements. Different sealing options should not be assumed to have one common operating envelope.
Will the existing flange spacing and bolts suit this replacement?
Compare the actual face-to-face space, flange dimensions, pipe bore and fasteners with the selected valve drawing. Include disc and operator clearance before approving the installation.
