WebEach size of AB-QM has predetermined flow ranges that the valves can be set to which is also part of sizing up what Valve to use, not just matching your pipework size. The AB-QM can be upgraded to work as a Pressure Independent Control Valve, or PICV for short, by adding an actuator. WebDec 13, 2024 · The valve is fitted with a spindle for manual opening. Make sure that the external pilot line is connected to the upper side of the main line so that any dirt and oil from the plant will not find its way into the pilot line. The valve is designed to withstand a high internal pressure.
