A Y Mcdonald Aym-72054t 3/4 Spring Check Valve Fnpt

Product Description

The A Y MCDONALD aym-72054t 3/4 is a 3/4-inch inline spring check valve with female NPT (FNPT) connections on both ends. Spring check valves allow flow in one direction and close automatically when flow stops or reverses, preventing backflow without requiring any external actuation. This valve is designed for in-line installation in pipe systems where backflow prevention is required. Licensed plumbers and pipefitters are the typical installers for this type of valve in commercial and residential applications.

This valve is suited for residential and light commercial plumbing, hydronic heating, and water distribution systems where a reliable, inline backflow prevention device is needed. The FNPT connections make it compatible with standard threaded pipe and fittings. Its inline design allows installation directly in the supply or return line without additional fittings or adapters beyond standard NPT connections.

Key Features

• Spring-loaded disc closes automatically to prevent backflow
• 3/4-inch female NPT (FNPT) connections on both ends for standard threaded pipe assembly
• Inline body design installs directly in the pipe run
• No external actuation or wiring required for operation

Compatibility

Designed as an OEM-style replacement or new-installation inline spring check valve for 3/4-inch FNPT threaded pipe systems in residential and light commercial plumbing and hydronic applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off water supply and relieve system pressure before installation. Apply thread sealant tape or compound to male threads before making up connections. Observe the flow-direction arrow marked on the valve body to ensure correct orientation in the line.
