The APOLLO VALVES 77-104-27 is a full port bronze ball valve designed for plumbing, HVAC, and light industrial piping systems where maintaining full flow and minimizing pressure drop are priorities. The full port bore matches the pipe inside diameter, eliminating the flow restriction common in standard port designs. A cast-in mounting pad is integrated into the valve body, allowing actuator mounting without additional hardware. At 3/4 inches, this valve fits common residential and commercial service line sizes. Licensed plumbers and pipefitters are the typical installers for this type of shutoff valve.
This valve is suited for residential and light commercial water distribution, hydronic heating systems, and general fluid handling applications where a reliable manual shutoff is required. The 3/4-inch size is a standard fit for branch lines, equipment isolation, and zone shutoff service. The full port design makes it appropriate for systems sensitive to pressure drop, including circulator loops and domestic hot and cold water lines.
Designed as an OEM-style replacement or new-installation ball valve for 3/4-inch plumbing and hydronic piping systems.
Installation is typically performed by a licensed plumber or pipefitter. Shut off the water supply and relieve system pressure before cutting into any existing line. Follow applicable local plumbing codes and IPC requirements for joint type, support spacing, and pressure testing after installation. Do not overtighten threaded connections on bronze fittings, as the material is susceptible to thread damage under excessive torque.
