2-inch CPVC true-union ball valve

The Spears 1839-020C is a 2-inch inline true-union ball valve moulded from CPVC for industrial and commercial fluid handling. Full-port construction provides unrestricted flow through socket and FNPT end connections on both unions. A locking tee handle made of polypropylene secures the valve position during operation.

Suited for CPVC systems needing inline isolation

Installers working with CPVC piping between 73 and 140 degrees Fahrenheit will find the FPM body seals and PTFE seats compatible with a wide range of chemicals. The Safe-T-Shear stem design adds protection against over-torque damage. Plumbers requiring metal-alloy bodies, higher temperature ratings or flanged end connections should select a different valve type.

235 psi maximum working pressure at 73 degrees F

This pressure rating defines the safe operating envelope for the valve body and seals in water service. Exceeding 235 psi or operating above 140 degrees Fahrenheit risks seal deformation and body stress beyond the published limits. Verify system pressure and temperature against this single figure before specifying the valve.

Questions about this item

What pipe size and connection type must my existing plumbing have to fit this 2 in CPVC ball valve?

The valve is designed for 2 in pipe with Socket/FNPT x Socket/FNPT connections, so your system must match that size and socket or threaded interface.

Will the PTFE seats and FPM seals hold up if the line sees temperatures up to 140 Degrees F?

Yes, the temperature range is rated 73 to 140 Degrees F, and the PTFE seat material with FPM body seals is specified for that range.

How can I confirm the Safe-T-Shear stem is functioning correctly after installation?

Operate the locking tee handle through its full quarter turn; smooth rotation and positive lock positions indicate the stem and ball are moving freely.
