QD947 Forged Steel Trunnion Ball Valve
QD947 is explicitly listed alongside QD47, QD347, QD647 and QD947 in the forged steel trunnion ball valve dimensional tables on printed pages 28-29 of the KOZO manufacturer catalog. This page covers the named base model; it does not invent a pressure, seat or material suffix.
Pressure and size selection
- PN16, PN25 and PN40 catalog tables: DN50-DN700
- PN64 and PN100 catalog tables: DN50-DN600
- Verbinding: flanged
- Bouw: forged steel trunnion ball valve
These are catalog selections, not a claim that one valve is rated for every listed pressure. Body material, zitplaats, nominal size, actuator package and operating duty must be selected together. Confirm fluid compatibility, pressure-temperature limits, final dimensions and available configurations with KOZO before ordering.
Pipeline isolation
The trunnion ball construction provides a fixed-ball arrangement for pipeline shutoff. Select the final configuration for the process fluid and installation; this page does not assert a special-alloy, cryogenic or certified service configuration.
Image and model reference
The main image is an original catalog cropped flanged valve-body sectional detail with the handle removed from view from printed page 28, carrying a KOZO VALVE watermark. It illustrates the catalog valve structure rather than the as-built appearance of a finished QD947 order. No specific pneumatic or electric actuator is pictured or asserted by this body-detail image. The QD347 worm-gear photograph has not been reused to impersonate this model.
