1-1/4" T-750 Stainless Check Valve

The Legend Valve 113-436 is a 1-1/4 inch T-750 check valve constructed from 316 stainless steel. It permits flow in one direction while automatically preventing reverse flow in plumbing installations. This component suits contractors and maintenance teams specifying corrosion-resistant alloy hardware for fluid control systems.

Threaded Connection Limits

The valve uses a 1-1/4 inch threaded end connection that determines the maximum pipe size it can join directly. System pressure must remain within the T-750 class rating for reliable sealing. Installers should verify that the thread standard matches the existing piping before assembly.

316 Alloy Capacity and Headroom

The 316 stainless steel body provides broad chemical compatibility for water, oil and many aggressive media where lesser alloys would degrade. It handles typical commercial plumbing pressures within its class rating. The design is not intended for services that exceed the T-750 pressure envelope or require larger bore diameters.
