  • CPVC body resists corrosive chemicals and water

  • True-union design enables inline removal without pipe cutting
  • Lever handle provides simple manual on-off control
  • Rated for 250 psi maximum operating pressure

CPVC Ball Valve True Union

The Chemtrol U51TB-V is a manual two-way ball valve built from CPVC for handling corrosive chemicals and water. It uses a three-piece straight body with a full-port CPVC ball and a lever handle for inline flow control. The valve carries a 250 psi maximum operating pressure rating.

Industrial and Commercial Plumbing Installers

This valve suits technicians who need a true-union CPVC valve for chemical or water lines where full-port flow and 250 psi pressure capacity are required. It is not intended for steam service, combustible gas lines or vacuum applications, and it does not carry a 3-A sanitary rating for food-grade processes.

3/4 Inch Nominal Size with 250 psi Rating

The 3/4 inch nominal size provides full-port capacity for standard chemical and water distribution lines. The 250 psi operating pressure gives headroom for typical industrial supply pressures, while the lack of steam, gas or vacuum ratings defines the limits of its approved service envelope.

Questions about this item

What pipe size and connection types must my existing plumbing have to install the 3/4" CPVC True Union ball valve?

The valve requires a 3/4 inch nominal pipe size with one socket end for solvent-weld CPVC pipe and one FNPT threaded end for a female NPT fitting.

Will the CPVC body and ball handle the same 250 psi pressure rating as my older metal valves in a corrosive chemical line?

Yes, the full-port CPVC ball and body are rated for 250 psi maximum operating pressure with corrosive chemicals and water.

How can I confirm the lever handle is correctly aligned after I assemble the true union ends?

The lever handle sits parallel to the flow path when the valve is open and perpendicular when closed, giving immediate visual confirmation.
