Midland 316 Stainless Steel Y-Spring Check Valve

Midland Y-Spring Check Valves are designed to prevent reverse flow in piping systems while maintaining dependable operation in both horizontal and vertical installations. The spring-loaded poppet provides fast, automatic shutoff to help protect pumps, compressors, and process equipment from backflow.

Manufactured from corrosion-resistant stainless steel, these compact check valves are suitable for water, air, oil, steam, and other compatible media in commercial and industrial applications.

Key Features

• Spring-loaded Y-pattern check valve design
• 316 stainless steel body for corrosion resistance
• Female NPT threaded connections
• Automatic backflow prevention
• Suitable for horizontal or vertical installation (flow upward in vertical applications)
• Compact, serviceable Y-body configuration
• Fast-closing spring minimizes water hammer
• Designed for commercial and industrial fluid handling systems

Construction Details

The stainless steel body provides excellent durability and resistance to corrosion in demanding service environments. The spring-loaded internal mechanism closes quickly when flow stops, reducing reverse flow and system shock.

The Y-pattern design allows convenient access to internal components for maintenance while maintaining efficient flow characteristics.

Important Notes

Install with the flow arrow pointing in the direction of system flow.

For vertical installations, flow should travel upward to ensure proper valve operation.

Verify pressure, temperature, and media compatibility before installation.
