RB01 Series full-flow ball valves are designed for air conditioning and refrig-eration applications where low pressure drop and optimum system performance are required, says the manufacturer. Servicing is simplified by the valve’s one-quarter turn, low-torque actuation. Brass body construction and copper connection tubes help eliminate corrosion-related problems. The units are available in three body sizes from 5/8 to 1 1/8 in. and handle refrigerating capacities up to 20 tons. Various connection sizes, gauge port locations, and mounting options are available.
