QDYQ340Y-6 Piston Flow and Pressure Regulating Valve
The pressure-specific model heading on printed page 06 of the KOZO flow and pressure regulating valve catalog shows drive-code alternatives 3, 6 και 9 and sealing-code alternatives H, F and Y. This page separates the 3 drive / Y sealing-code / 6 pressure entry as QDYQ340Y-6; body-material codes are not multiplied into unverified products.
Features and applications
The piston-type design adjusts the flow passage for flow regulation and pressure management. The catalog describes reservoir discharge, long-distance water transmission, waterworks and municipal water networks. Confirm flow range, valve sizing, pressure differential and installation duty with KOZO for the intended service.
Catalog specifications
- Μοντέλο: QDYQ340Y-6
- Nominal pressure designation: ΠΝ6
- Listed size range: DN150-DN2000

C, εγώ, P and R remain selectable body-material codes. The actual body grade, seat material and temperature capability must be confirmed together for the selected configuration. The sealing-code letter is preserved from the source, not used to invent a specific alloy or unverified temperature rating. Gearbox selection and operating torque depend on valve size and duty. No special-alloy, cryogenic or certification claim is inferred.
Original image reference
The main image is an original catalog worm gear series photograph, not proof of a separately verified pressure-, κάθισμα- or material-specific finished order. The image carries a KOZO VALVE watermark and retains the original catalog structure without generated hardware. Appearance and dimensions vary with size, pressure and configuration. Request a configuration-specific drawing and actual product photograph before confirming an order.
