Legend Valve 201-237 True Union Ball Valve
The Legend Valve 201-237 is a 1-1/2 inch S-643 PVC true union ball valve with flanged connections. It is designed for fluid control in air compressor and vacuum pump systems. The true union design allows the valve body to be removed from the piping for maintenance or replacement. This new component suits installers and maintenance teams working on industrial or commercial pneumatic lines.
S-643 PVC Material and Flanged Ends
The valve body uses S-643 PVC construction rated for the chemical environment indicated by the Proposition 65 warnings. Flanged ends provide a bolted connection method that aligns with matching flanges on the pipework. Buyers must verify that the S-643 PVC material is compatible with their specific media, temperature range and pressure requirements before installation.
True Union Design for Inline Service
The true union configuration lets technicians break the union nuts to lift the valve body out without cutting the surrounding pipe. This frees up labour time during routine servicing or seal replacement on compressor discharge or vacuum inlet lines. The flanged connections require compatible mating flanges, gaskets and bolt kits which are not included with this valve. Systems needing solvent-weld or threaded ends instead of flanged connections cannot use this specific model.

Questions about this item
What does the 1-1/2 inch size mean when the valve is installed in a pipe run?
The 1-1/2 inch size matches a nominal 1-1/2 inch pipe bore so flow capacity is sized for that diameter.
How does the flanged connection work and what pressure rating does it cap at?
The flanged ends bolt to mating flanges with a gasket; the pressure rating is set by the PVC body and flange class.
What clearance and mounting pattern does the true union body need to fit?
The true union design lets you remove the centre section by unthreading the union nuts, so you need space for the face-to-face length plus nut swing room.
