Product Overview
The KOZO A105N Forged Piston Check Valve is designed for compact high-pressure non-return service where a guided piston or lift element closes automatically as forward flow decreases or reverses. The guided internal movement can provide stable operation in suitable small-bore clean-fluid systems.
Why A105N?
ASTM A105N is a normalized forged carbon-steel grade widely used in high-pressure piping components. It provides a strong and compact pressure-containing body for oil, 가스, steam and industrial utility service when the material is compatible with the process conditions.
Key Design Features
- ASTM A105N forged body.
- Guided piston/lift-style non-return element.
- API 602 / ASME B16.34 design family.
- SW, threaded or flanged connection options.
- Compact small-bore high-pressure construction.

Selection Notes
Installation orientation, minimum flow, pressure drop and fluid cleanliness should be reviewed for stable piston-check operation. Dirty or solids-containing fluids may require a different check-valve design.
How to Specify
Please provide size, pressure class, 중간, design temperature, end connection, trim/piston material and required test standard.
FAQ
Does this valve need external actuation?
No. The piston opens and closes automatically according to differential pressure and flow direction.
