Apollo Valves 77C-105-01A Bronze Ball Valve 1 Inch Npt

Product Description

The APOLLO VALVES 77C-105-01A is a full-port bronze ball valve designed for plumbing and mechanical systems where reliable shut-off and strong flow characteristics are required. Built around a solid chrome-plated ball, this valve minimizes flow restriction and resists corrosion over extended service life. The body and end cap are cast from U.S.-made bronze, providing durability suited to commercial and residential installations. The 1-inch NPT connection makes it compatible with standard threaded pipe systems. It is installed by licensed plumbers and pipefitters working on water distribution, hydronic heating, and general fluid-handling applications.

The 77C-105-01A belongs to the Contractor Series, which omits the mounting pad to reduce cost without sacrificing core performance. This makes it well suited for high-volume or budget-conscious installations where a mounting pad is not required. The full-port design ensures minimal pressure drop across the valve, which is critical in systems where flow rate and system efficiency matter. The 1-inch NPT threading allows direct installation into standard pipe runs without adapters.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with local plumbing codes and IPC guidelines. Shut off system pressure and drain the line before removing or installing the valve. Apply thread sealant or PTFE tape to NPT threads as required by local code. Do not over-tighten the valve body against fittings, as bronze threads can be damaged by excessive torque.
