Apollo Valves 77C-104-01A Ball Valve 3/4 Inch Npt

Product Description

The APOLLO VALVES 77C-104-01A is a full-port bronze ball valve designed for shutoff and flow-control service in plumbing, HVAC, and light industrial piping systems. It features a 3/4-inch NPT threaded connection and a full-port bore, which minimizes pressure drop across the valve and maintains full flow capacity through the line. The bronze body resists corrosion in both water and many fluid-service applications. Licensed plumbers and HVAC technicians install this valve on supply lines, equipment isolation points, and distribution manifolds where a reliable, low-restriction shutoff is required.

This valve is suited for residential and light commercial plumbing and mechanical systems. Typical applications include domestic water supply, hydronic heating and cooling circuits, and equipment isolation on boilers, chillers, fan coil units, and similar mechanical equipment. The 3/4-inch NPT thread size fits standard pipe configurations commonly found in these system types. It is sold and packaged as a single unit.

Key Features

• Full-port design minimizes pressure drop and maintains unrestricted flow
• 3/4-inch NPT threaded connections for standard pipe compatibility
• Bronze body construction for corrosion resistance in water service
• Quarter-turn operation for fast, positive shutoff
• Compact form factor at 0.7 pounds for easy handling in tight spaces

Compatibility

Designed as an OEM-style replacement or new-installation ball valve for residential and light commercial plumbing and HVAC piping systems using 3/4-inch NPT threaded connections.

Installation Notes

Installation should be performed by a licensed plumber or qualified mechanical contractor in accordance with applicable local plumbing codes and the IPC. Shut off the water supply and relieve system pressure before removing or installing any valve. Apply thread sealant or PTFE tape to NPT threads before assembly and tighten to hand-tight plus the appropriate number of turns per standard pipe-fitting practice. Do not over-torque bronze fittings, as this can crack the body.
