Apollo Valves 77C-103-01A 1/2 Inch Npt Full Port Bronze Ball Valve

Product Description

The APOLLO VALVES 77C-103-01A is a full-port bronze ball valve designed for plumbing, HVAC, and mechanical piping systems where reliable shutoff and high flow capacity are required. The valve features a solid chrome-plated ball that minimizes flow restriction and provides long-lasting sealing performance. The body and end cap are cast from U.S.-made bronze, giving the valve the structural integrity needed for commercial and residential service. This is a Contractor Series valve, meaning it ships without a mounting pad, making it a cost-effective choice for standard inline installations. Licensed plumbers and mechanical contractors are the primary installers.

The 77C-103-01A is suited for residential and light commercial plumbing, hydronic heating, and HVAC piping applications where a 1/2 inch NPT full-port shutoff is needed. The full-port design supports maximum flow rates, reducing pressure drop across the valve. NPT threaded end connections conform to ANSI B16.18 standards, making this valve compatible with standard pipe and fitting assemblies used in domestic water, hydronic, and general mechanical systems.

Key Features

• Full-port design for maximum flow and minimal pressure drop
• Solid chrome-plated ball for durable, consistent sealing
• U.S.-made cast bronze body and end cap for corrosion resistance

Compatibility

Designed as an OEM-style replacement or new-installation ball valve for standard 1/2 inch NPT plumbing and mechanical piping systems.

Installation Notes

Installation should be performed by a licensed plumber or qualified mechanical contractor in accordance with applicable local plumbing codes and ANSI standards. Shut off the water supply and relieve system pressure completely before removing or installing any valve. Use appropriate thread sealant or PTFE tape on NPT connections and tighten to the fitting manufacturer's recommended engagement — do not over-torque bronze fittings. Verify flow direction and handle orientation before returning the system to service.
