Description

QDYQ940H-25 Electric Piston Flow and Pressure Regulating Valve

The QDYQ piston design adjusts the flow passage for flow regulation and pressure management. Electric actuation supports powered positioning; actuator controls, supply voltage, enclosure protection and required torque are selected for each order, not specified by this base model code alone.

Applications

The manufacturer catalog describes reservoir discharge, long-distance water transmission, waterworks and municipal water networks. Confirm pressure differential, fluid compatibility and control duty with KOZO before selection.

Catalog specifications

  • Model: QDYQ940H-25
  • Pressure designation: PN25
  • Listed valve size range: DN150-DN2000
  • Actuation: electric
  • Connection: flanged

Configuration and photo reference

The model table on printed page 09 of the KOZO flow and pressure regulating valve catalog lists drive-code alternatives 3, 6 and 9. This page represents the electric 9 variant with sealing code H. Body-material codes C, I, P and R remain selectable catalog options; no separately verified material-specific configuration is asserted here.

The original electric-actuated series photograph is extracted from printed page 07 and carries a KOZO VALVE watermark. It illustrates the electric QDYQ series rather than a pressure-, size- or material-specific finished order. Appearance, dimensions, actuator and sealing specification vary with the selected configuration. Confirm final specifications and availability before ordering.
