FAQ
How should this valve be configured for the application?
Specify the flange standard, pressure class, service medium and whether an actuator mounting pad is required. Final selection must be verified against the actual medium, pressure, temperature and applicable piping standard.
Can this ball valve be automated?
Manual lever operation is standard; ISO 5211 direct mounting supports pneumatic or electric actuation.
What documents can be supplied for a project order?
Material certificate, hydrostatic test record, dimensional drawing, packing list and certificate of conformity can be provided when specified in the order.
Do pressure and temperature ratings apply to every configuration?
No. Ratings depend on the selected body material, seat, packing, end connection and service fluid. Confirm the final pressure-temperature limit with the selected supplier before purchase.
