Y-type check valves are designed to allow fluid flow in one direction while preventing reverse flow caused by back pressure. They are commonly used to protect pumps and other equipment from damage due to flow reversal.

Swing check valves, in particular, are built to minimize pressure drop across the line. Their design offers a reliable seal and fast closure when needed.

Design Features

- Manufactured in accordance with API 602
- Available with socket weld, threaded, or combined end connections
- Bolted or welded bonnet options
- Low fugitive emissions
- NACE compliance: MR-0175 or MR-0103
- Pressure tested to API 598
- Body-to-cover joint ensures uniform gasket load for leak-tight sealing

The disc is connected to the hanger in a way that allows controlled movement, helping maintain proper alignment with the seat during closure.

A welded disc nut secures the connection and prevents loosening due to vibration or impact during operation.

Stellite seat rings provide increased durability against wear, abrasion, and erosion on the sealing surfaces.
