Understanding Compression Ball Valves

Compression ball valves secure to pipes using compression fittings, creating a tight, leak-free seal without soldering. Inside, a rotating ball with a central bore controls water flow—aligning with the pipe to allow flow or blocking it completely when turned. This simple mechanism ensures durability, reliability, and quick isolation during maintenance or emergencies.

Materials and Build Quality

Crafted from brass with chrome plating, the valve resists wear, corrosion, and tarnish. Every component—from the lever to the seals—reflects attention to detail, ensuring years of reliable service even in demanding environments.

Advantages of Lever-Operated Stops

• Smooth, user-friendly operation compared to traditional stop valves
• Clear visual feedback for open/closed status
• Quick shut-off during emergencies or routine maintenance
• Saves time and effort with efficient design

Step-by-Step Installation Guide

1. Gather tools: pipe cutter, adjustable spanner, PTFE tape
2. Turn off main water supply and drain pipes
3. Cut pipe cleanly and deburr ends
4. Slide compression nut and olive onto pipe, position valve
5. Wrap PTFE tape around threads for watertight seal
6. Tighten compression nuts carefully—avoid overtightening
7. Restore water supply and check for leaks

Maintenance Tips

• Inspect regularly for leaks, corrosion, or wear
• Operate lever periodically to prevent seizing
• Clean mineral buildup with mild solution and soft brush
• Tighten fittings as needed, but avoid over-tightening

Common Applications

• Residential plumbing: isolating sinks, toilets, appliances during maintenance
• Industrial setups: managing water supply lines, process feeds, and emergency shut-offs
• Versatile for both domestic and commercial use thanks to compression fittings

Troubleshooting

• Leaks: check joints, compression rings, and pipe ends for clean cuts
• Stiff lever: may indicate mineral buildup or internal wear
• Incomplete shut-off: inspect washers or seals for damage
