Product Overview
The KOZO DIN Swing Check Valve is designed for automatic backflow prevention in European-standard industrial piping. Forward flow lifts the disc from the seat; when flow decreases or reverses, the disc swings back toward the seat without external actuation.
Key Design Features
- Swing-disc non-return mechanism: Simple automatic operation using flow direction and differential pressure.
- DIN/EN dimensional system: Suitable for European-standard piping layouts.
- Wide size range: DN40–DN900 family for utility and process systems.
- Multiple pressure ratings: PN16–PN100 depending on design and material.
- Flanged installation: EN-standard flanged connection family.

Selection Notes
Swing-check performance depends on flow velocity, installation orientation, minimum opening flow and system transients. Oversizing can cause unstable disc movement or repeated impact. Bahan, seat and temperature limits must be selected from the actual service conditions.
How to Specify
Please provide DN, PN rating, body/trim material, medium, design pressure, design temperature, flange standard, installation orientation and quantity.
Pertanyaan Umum
Does a swing check valve require an actuator?
No. It opens and closes automatically from flow direction and differential pressure.
Can it be installed vertically?
Some configurations can, but orientation should be confirmed for the specific design and flow direction before installation.
