FAQ How do I switch this valve from 5/2 to 3/2 operation?The 551 series valves can be converted by repositioning a gasket on the valve body. You need to open the valve body and move the specific gasket to block the correct internal port, as shown in the manufacturer’s installation manual. What is the flow rate (Kv or Cv) of the G551A001 MS?The G551A001 MS with G1/4 ports has a nominal flow rate of approximately 700 l/min (ANR), which corresponds to a Kv value of around 0.75. Always consult the official ASCO/Emerson datasheet for precise performance curves. Can I mount a solenoid coil directly on this valve?This specific model, G551A001 MS, is an air-piloted valve with a spring return and a manual override. To use a solenoid, you would need the corresponding solenoid-piloted version from the 551 series, which includes the solenoid operator assembly. This body is not designed for direct coil mounting.
