Supply valves for a two-pipe system are the globe type and are made in a number of different patterns; angle, straightway, right hand or left hand. Installation for the system is made at the inlet connection. The angle pattern valve is most commonly used because it is easily adaptable to most heating unit installations. When the inlet connection is below the unit, the straightway pattern is installed in a vertical connection to a convector.
