The Barber Colman VB-7273-0-4-01 is a 1/2-inch, two-way globe valve engineered for precision flow control in HVAC and light industrial process applications. It features a linear flow characteristic with a low Cv of 0.4, making it ideal for systems requiring fine modulation. The valve body is constructed from bronze with stainless steel internal trim for durability and corrosion resistance. Designed with a stem-up-to-open configuration, it is suitable for use with compatible Barber Colman actuators.
