Philip, I wanted the highest peformance solution. The valve has a flow rate equivalent to over twenty 1/2 Burkert type solenoid valves or four 1 solenoid valves. Another problem with solenoid valves is their opening times, typically 0.5 to 2 seconds, I will be opening the ball valve in 20-30mS. End result is maximum flow rates in the shortest possible time which probably means self-destruction but you have to try
