Compact two-way ball valve with a union joint, 1.5" female pipe thread to 1.5" male pipe thread, built for straightforward flow control in plumbing systems.

This CMP 25802-651-000 valve is a durable, two-port ball valve that connects plumbing runs via a union and standard pipe threads.

The union simplifies installation and service by allowing the valve to be removed without disturbing adjacent piping.

How does this two-way ball valve simplify installation and maintenance?

The included union lets you detach the valve from the pipe without cutting or disassembling the entire line, saving time during installation or replacement. The 1.5" FPT and 1.5" MPT threads match common pipe fittings and reduce the need for adapters.

• Union joint enables quick removal for service or replacement

• Two-port ball design provides a clear open/closed flow path
• Threaded connections minimize extra fittings

What flow control performance can I expect from this CMP valve?

As a two-way ball valve, it provides reliable shutoff with low pressure drop when open. The quarter-turn ball mechanism gives fast actuation and a tight seal when closed, suitable for many water and non-hazardous fluid piping systems.

• Two-port configuration for simple on/off service
• Quarter-turn operation for rapid opening and closing
• Ball design reduces turbulence and maintains steady flow
• Appropriate for common plumbing fluids and general-purpose systems

Which applications and plumbing systems is this valve compatible with?

Confirm thread types and sizes match your existing plumbing: this model has a 1.5" FPT on one end and a 1.5" MPT on the other, with a union for serviceability. Also verify material compatibility with your fluid and that the valve’s pressure and temperature limits suit your system.

• Verify 1.5" female pipe thread and 1.5" male pipe thread match your fittings
• Confirm the valve’s materials are compatible with the fluid in your system
• Ensure pressure and temperature ratings meet your application needs
