  • Chrome-plated brass ball ensures smooth, reliable operation
  • Lever handle provides quick manual control

Manual two-way bronze ball valve

This manual two-way ball valve has a bronze body and a chrome-plated brass ball in a full-port design. It is built for inline use with air, steam or water and features a lever handle for quarter-turn operation. The two-piece construction suits residential and light-commercial plumbing installations.

Rated for 600 psi operating pressure

The valve handles a maximum operating pressure of 600 psi and the same rating for steam service. No combustible-gas or vacuum ratings are provided, so it is intended for standard water, air and steam lines. Bronze construction and chrome-plated brass internals resist corrosion during normal use.

Full-port 3/4 in FNPT inline connection

The 3/4 inch FNPT threads connect directly to matching pipe without adapters and the full-port bore maintains flow capacity through the valve. Two-piece body construction allows the valve to be serviced in-line when required. Lever handle gives clear visual indication of open or closed position.

Questions about this item

How do I install the 3/4" FNPT bronze ball valve inline and what step is often missed?

Thread the valve onto 3/4" FNPT piping using suitable sealant, tighten to the manufacturer's torque specification, and ensure the lever handle moves freely; the step often missed is confirming the valve body is oriented for the correct flow direction before final tightening.

What maintenance or replacement will the chrome-plated brass ball and bronze body need over time?

Periodically operate the lever to prevent seizing, inspect the packing nut for leaks and tighten if necessary, and replace the valve if the ball shows pitting or the seats no longer seal at the rated 600 psi.

What is the first limit reached under sustained use at the maximum 600 psi steam rating?

The steam pressure limit of 600 psi is the primary constraint; sustained operation at this pressure and temperature will accelerate seat wear and packing degradation before the bronze body or chrome-plated brass ball reaches its structural limit.
