Quality valve

Just installed. Seems like quality valve actuator. It is a NO (normally open) valve actuator and need to be powered for the valve to close. I would have liked to have an actuator that goes the other way around but the alternatives where more and expensive and did not justify the costs for me. I ordered them together with the ASC2.1/18 limit switch which is working very well. I was a bit worried that they wouldn't on my old Regin MGN valves but they fir perfectly. (It is a M30 x 1,5 connection)
