DYQ340Y-1.6 Top-Entry Eccentric Semi-Ball Valve
The 1.6 MPa dimensional table on printed page17 explicitly lists DYQ340 with H, Y and F alternatives. This page separates DYQ340Y-1.6 while retaining the catalog’s 1.6 pressure spelling; this corresponds to PN16, not a separate pressure rating from the -16 notation on older series pages.
Features and use
The top-entry construction provides access to the semi-ball components through the upper cover. The catalog describes water pipelines, pumping systems and municipal service. Confirm fluid compatibility, valve sizing, pressure differential and operating duty for the selected configuration.
Catalog selection
- Model: DYQ340Y-1.6
- Catalog sealing code: Y
- Actuation: worm gear
- Connection: flanged
- Nominal pressure: 1.6 MPa / PN16
- Listed dimensional range: DN50-DN2000
H/F/Y identify separate catalog sealing variants; actual sealing material and temperature capability require confirmation. Body-material options are not separately verified grades on this page. Gearbox torque and dimensions depend on the selected size and duty. No special-alloy, cryogenic or certification claim is inferred from the image.
Original photo
The main image is the manufacturer’s original worm-gear top-entry series photo from printed page15, with a KOZO VALVE watermark applied to the valve body. It illustrates series appearance, not a pressure-, seat-, size- or material-specific finished order. Request an order-specific drawing and actual product photo before confirming specifications.
