Frequently Asked Questions
What air and control data should I provide for this pneumatic butterfly valve?
Specify the available air supply, required on-off or modulating duty, failure response and command and feedback requirements. Ask for the exact actuator and accessories to be identified in the quotation.
What does the high-performance description tell me about the supplied construction?
Request the selected body connection, disc geometry, seat and sealing materials on the datasheet. The description alone does not confirm a specific offset design, leakage class or operating range.
Which materials should I confirm in addition to the carbon-steel body?
Provide the medium and operating conditions and ask for the disc, stem, seat and seal specification as well as the actual body grade. Confirm the complete wetted arrangement before purchase.
