Angle ball valve No name H/A3 1/2" x 3/4" for plumbing connections

The Angle ball valve No name H/A3 1/2" x 3/4" for plumbing connections is a compact right-angle shut-off valve designed for water supply systems. It features a ball closure mechanism that provides straightforward on/off control, and a 90-degree body shape that allows installation in confined spaces or where a change in flow direction is required. The valve is intended for use in residential and commercial plumbing to isolate branch circuits, enable maintenance, and stop water flow quickly and reliably.

Advantages

The valve offers a simple quarter-turn operation and a durable ball mechanism that minimizes leakage when fully closed. Its angled body reduces the need for additional fittings, saving space and installation time. The compact construction and commonly sized 1/2" x 3/4" connections make it compatible with standard piping in many applications. Materials and internal sealing are chosen for water service to sustain repeated use and basic mechanical stress.

Suitable for

• Residential water supply shut-off points
• Isolation of branch circuits in commercial buildings
• Under-sink and appliance connections
• Plumbing maintenance and repair tasks

Key specifications

• Connection sizes: 1/2" x 3/4"
• Configuration: right-angle (90°) body
• Closure type: ball valve (quarter-turn)
• Intended medium: potable water and general water supply
• Typical applications: shut-off, isolation, maintenance

How to use

Install the angle ball valve in-line with the piping so the threaded or soldered connections match the system fittings. Ensure the flow direction and orientation suit the right-angle body. Tighten connections to the recommended torque for the piping material and test for leaks after installation. Operate the valve with a quarter-turn clockwise to close and counterclockwise to open; verify smooth operation before returning the system to normal service.

Usage recommendations

Before installation, flush the pipe to remove debris that could damage the ball or sealing surfaces. Use compatible sealing materials on threaded joints and avoid overtightening. For long-term reliability, exercise the valve periodically and inspect seals if the valve is exposed to prolonged stagnant water or infrequent use.
