Product Identity
The Legend Valve 201-239 is a 2-1/2 inch PVC true union ball valve with flanged ends. It is designed for technicians and plant operators who need a reliable shut-off component in fluid handling systems. The true union design allows the valve body to be removed from the line without disturbing the connected piping.
Interface Constraints
The flanged connection pattern requires matching bolt-hole alignment and compatible flange dimensions on the mating pipework. PVC construction limits the assembly to applications where the media and temperature range fall within the material's chemical resistance envelope. The true union nuts must be accessible for disassembly during maintenance or replacement cycles.
Decisive Specification
The S-643 designation identifies the specific valve configuration and material grade that determines chemical compatibility and pressure rating. Buyers must verify this code against their system specifications to confirm the part matches the required service conditions. Systems requiring a different pressure class or elastomer seal will need an alternative valve model.

Questions about this item
Should I choose the 201-239 model or the S-643 version for my piping system?
Both numbers refer to the same valve; 201-239 is the catalogue code and S-643 identifies the true-union ball design, so you are selecting a single product.
What does the 2-1/2 inch size mean when the valve is installed in a line?
It matches a two-and-a-half inch nominal pipe bore, giving a full-port flow path through the PVC body and ball.
How do the flanged ends connect to the rest of the system?
The integral flanges bolt to matching flanged pipe or fittings, creating a rigid joint that can be unbolted for valve removal.
