Frequently Asked Questions
Can this JIS 20K ball valve replace an existing JIS 10K valve?
Do not assume direct interchangeability. Compare the required pressure-temperature rating, valve size, flange dimensions, facing and face-to-face length for the actual piping and selected valve. Confirm the replacement against the approved drawing before installation.
What should I confirm before choosing the handle-operated version?
Confirm the selected size, medium, operating conditions, differential pressure and the space needed for lever travel. Ask for confirmation that manual operation is appropriate for the required valve configuration rather than choosing solely from the product title.
What details should I include in an inquiry for this JIS 20K model?
Specify the required size, body-material option, connection and operating method, together with the medium and pressure-temperature conditions. State the applicable piping specification and any required inspection documentation so the order can be checked against the selected configuration.
