NIBCO notes installers can save up to 75% in installation time with the company’s new press transition ball valves. The press-by-PEX design needs no extra components to transition from copper piping to PEX. That makes connections form a one piping system easier and faster, while eliminating additional hardware and potential leak paths. The NIBCO family of transition valves features the only press-by-PEX configuration available today, the company notes. Other configurations include press-by-union threaded, press-by-union solder and press-by-union male.
