Engineering selection support

How to choose the right configuration

Use these distinctions to narrow your shortlist, then confirm the final specification with AMCO's engineering team.

Centric disc vs double offset

The disc geometry and pressure rating narrow the choice first.

  • Centric disc (PN10 – PN25): listed with PN pressure ratings; confirm seat material against the fluid.
  • Double offset (150# / 300#): listed with ASME pressure classes; confirm the required shutoff class.
  • Operation: check the available operators (lever, gear, actuator) on each product page.

Body style selection

Pick the body style that fits the installation and maintenance needs.

  • Wafer / semi-lugged: compact, clamped between pipe flanges.
  • Full lugged: threaded lugs on the full body; review end-of-line and dismantling needs.
  • Flanged / double flanged: integral flanges; confirm face-to-face length and drilling.
