FAQ
How should this valve be configured for the application?
Confirm adjustment range, nominal size, flange drilling, pressure class and operating torque. Final selection must be verified against the actual medium, pressure, temperature, pressure drop and applicable piping standard.
Can this valve be automated?
Yes. Pneumatic or electric actuation can be specified when the mounting interface, operating torque, cycle time and fail position are defined.
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, trim, seat, packing, end connection and service fluid. Confirm the final pressure-temperature limit with the selected supplier before purchase.
