4 Inch Brass Swing Check Valve

The Legend Valve 105-111 T-451 is a 4 inch brass swing check valve designed for plumbing installations. It permits flow in one direction and automatically closes to prevent backflow when pressure drops. The brass body provides corrosion resistance for water supply lines. This new component is intended for professional fitters and experienced DIYers.

Suitable for horizontal

This valve suits systems requiring a 4 inch nominal connection with a swing-disc mechanism to stop reverse flow. It is not for applications needing a spring-loaded silent check valve or a lift-check design. Buyers who want a smaller bore, a different body material, or a valve rated for steam service should look elsewhere.

4 inch nominal size

The single specification that decides fit is the 4 inch nominal diameter, which must match the pipework exactly. The swing-check action relies on gravity or back-pressure to seat the disc, so orientation and flow velocity matter. Verify the 105-111 T-451 marking against your project schedule before installation.

Questions about this item

Will the 4 inch T-451 swing check valve mate with my existing 4 inch brass piping?

The valve is a 4 inch brass swing check design, so it threads into standard 4 inch brass pipe fittings without adapters.

How can I verify the T-451 is sealing properly once installed?

Pressurise the line and watch for back-flow; the swing disc should close silently and hold pressure without leakage.

Does the 105-111 package include flange gaskets or thread sealant?

The box contains only the 4 inch T-451 brass swing check valve; gaskets and sealant must be purchased separately.
