Legend Valve 105-102 T-451 Brass Swing Check Valve

The Legend Valve 105-102 is a 3/8 inch T-451 brass swing check valve designed for plumbing systems requiring unidirectional flow control. It suits installers and maintenance technicians working on water lines where backflow prevention is needed. The valve uses a swinging disc mechanism that opens with forward pressure and closes against reverse flow. California Proposition 65 warnings apply because the product contains chemicals known to cause cancer and birth defects or other reproductive harm.

Sustained load behaviour

Under continuous flow the brass body and swing disc maintain a consistent seal without the chatter sometimes heard in spring-loaded designs during pressure fluctuations. The hinge pin and disc are built to withstand repeated cycling over long service periods in residential or light commercial installations. No specific pressure or temperature ratings are provided in the supplied data, so long-term performance at elevated conditions should be verified against the manufacturer's technical documentation before specifying the valve for critical duties.

Pre-order checks

Confirm the 3/8 inch connection matches the pipe size and thread type in the existing system before ordering. Review the Proposition 65 notice if the installation falls under California regulatory scope or if local codes require disclosure of listed chemicals. Ensure the swing-check orientation suits the flow direction and that there is sufficient straight pipe run for the disc to operate freely. The manufacturer ships direct on orders of 75 or more, which may affect lead time for single-unit purchases.

Questions about this item

How much heat does the 105-102 3/8" T-451 brass swing check valve generate when installed in a continuously flowing water line?

The valve body is solid brass with no moving parts that create friction, so it adds no measurable heat to the water stream during all-day operation.

What pipe fittings or thread sealant must I already have to connect the 105-102 3/8" T-451 valve into my existing plumbing?

You need two 3/8-inch female NPT fittings and a compatible thread sealant such as PTFE tape or pipe dope rated for potable water.

Will the 105-102 3/8" T-451 valve seat reliably against mineral deposits that build up on older galvanised or copper pipe?

The brass swing disc seats against a brass seat; light scale is pushed aside, but heavy encrustation on old pipe may prevent full closure and should be cleaned first.
