Frequently Asked Questions
How do I confirm that my quotation is for the JIS 20K configuration?
State the required pressure designation and actual service conditions on the inquiry and ask for the selected valve rating and connection details on the order documents. Do not infer one supplied configuration from the wider series options.
Will the wafer valve match my existing flange pair?
Provide the actual flange standard and dimensions, facing, fasteners and pipe bore. Check the selected drawing for face-to-face fit and disc clearance rather than assuming every JIS flange pair is interchangeable.
Which seat and operating arrangement should I specify?
The page describes different seat and drive alternatives. Identify the required medium, conditions, shutoff duty and operating method and request the exact selected configuration on the datasheet.
