Válvula de bola de muñón de acero forjado QD647
QD647 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
- Conexión: bridado
- Construcción: forged steel trunnion ball valve
These are catalog selections, not a claim that one valve is rated for every listed pressure. Body material, asiento, 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 QD647 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.
