BALLSTOP CALEFFI 323080 — ball valve with integrated check valve for domestic water 1 1/2" lever handle

CALEFFI BALLSTOP 323080 is a 1 1/2" ball valve with an integrated check valve and lever handle designed for domestic water systems. The product combines a quarter-turn shut-off ball valve with backflow prevention in a single compact body, allowing reliable isolation and protection of potable water installations where space is limited. Typical applications include service connections, meter bypasses and maintenance isolation in residential and light commercial plumbing systems.

Advantages

The integrated check valve eliminates the need for a separate backflow device, reducing installation time and components. A robust lever handle ensures quick quarter-turn operation for fast shut-off, while the ball valve design provides tight sealing and low pressure drop. The compact construction simplifies placement in tight service spaces and near water meters, and materials selected for potable water applications ensure corrosion resistance and long-term reliability.

Suitable for

• Service connections to domestic potable water supply
• Bypass lines and meter bypass arrangements
• Maintenance isolation for appliances and fixtures
• Light commercial plumbing installations requiring backflow prevention

Key specifications

• Connection size: 1 1/2" (nominal pipe size)
• Valve type: quarter-turn ball valve with integrated check valve
• Actuation: lever handle for manual operation
• Application: potable/domestic water distribution
• Function: shut-off with built-in backflow prevention
• Construction: compact body suitable for installation near meters and in limited spaces

How to use

Install the valve in the water line following applicable plumbing codes and orientation recommendations so that the integrated check valve is positioned correctly relative to flow direction. Use the lever handle to perform a quarter-turn shut-off for isolation during maintenance or meter servicing. Verify proper sealing after installation by pressurizing the line and checking for leaks; the integrated check valve will prevent reverse flow when the line downstream is depressurized. If required, flush the system to remove debris prior to placing the valve into regular service.

Usage recommendations

For reliable performance, install the valve where it can be accessed for operation and inspection. Avoid exposure to freezing conditions unless the system is drained or insulated. Periodically operate the lever to prevent seizing and inspect external joints for corrosion. Follow local regulations for backflow protection and metering when using the valve in meter bypass or service connection applications.
