Product overview

Control water flow through a larger pool or spa plumbing system with the Pentair FullFloXF 2-Way Diverter Valve. Part 263059 is a straight, two-port CPVC valve designed for 2½-inch pipe connections inside the ports or 3-inch slip connections over the outside of the ports. Its diverter design provides positive shutoff with low head loss.

This valve is a practical choice when replacing a compatible two-way valve or building a plumbing layout that needs manual flow control. Its adjustable stop positions help set the desired operating range, and the valve is designed to work with most industry-standard valve actuators when automation is needed.

Key features

• Two-way flow control: Opens, closes, or adjusts flow through one plumbing line.
• Dual-size connection options: Accepts 2½-inch pipe inside or 3-inch fittings over the outside of the ports.
• CPVC construction: Suited to pool and spa plumbing applications.
• Positive-seal diverter: Features a PTFE-coated diverter seal.
• Adjustable stops: Allows the handle’s travel limits to be set for the installation.
• Automation compatible: Designed for use with most industry-standard valve actuators; actuator sold separately.

Specifications

Installation and replacement guidance

Confirm the existing valve’s port size, plumbing layout, and available installation space before ordering. The 2½-inch and 3-inch measurements describe two ways to connect to the same valve ports; they are not separate inlet and outlet sizes. Use the appropriate fittings and installation method for the chosen connection.

Shut off the pump and relieve system pressure before servicing pool plumbing. A qualified pool professional can confirm proper valve orientation, plumbing connections, and actuator setup if the valve will be automated.

Frequently asked questions

Is this a check valve?
No. Part 263059 is a manually operated 2-way diverter valve. A check valve serves a different purpose.

Does it include an electric actuator?
No. This listing is for the valve. An actuator must be purchased separately if automated operation is required.

Will it fit both 2½-inch and 3-inch plumbing?
Yes. The ports accept 2½-inch pipe internally or a 3-inch slip connection externally. Verify your fittings before installation.
