How should this valve be configured for the application?

Confirm Class, flange bore, seat type and material compatibility before selecting the final configuration. Final selection must be verified against the actual medium, pressure, temperature, flow direction and applicable piping standard.

Does this check or foot valve need an actuator?

No. Check and foot valves operate automatically from flow and differential pressure; select the correct cracking pressure, orientation and internal design for the service.

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, trim, end connection and service fluid. Confirm the final pressure-temperature limit with the selected supplier before purchase.
