Overview
The Walworth A105N check valve (model 5540SW) is a precision-engineered forged steel valve designed to prevent reverse flow in industrial piping systems. The A105N material is a carbon steel grade suitable for non-corrosive applications including water, oil and gases at temperatures between -20°F and +800°F. This valve combines robust construction with reliable automatic flow control, making it ideal for demanding industrial and commercial fluid-handling applications.
Key Features
- Forged steel A105N body for superior durability and resistance to fatigue
- Automatically stops reversal of flow promptly
- Wide temperature range: -20°F to +800°F (-30°C to +425°C)
- Suitable for water, oil, and gas service
- Straight-through flow design minimizes pressure loss
- Low friction disc for smooth operation
