Seeking knowledge on solenoid valves
Thread Content
My installation is new and it has solenoid control valves; this is my first time dealing with them. Does the solenoid valve activate to cut off the flow only when power is lost to the installation, and does it automatically resume functioning once power is restored? How do I use the two black buttons on the solenoid valve? Thank you, extra points appreciated
The knob below is used to select local operation or remote control; the knob above is used to open and close the valve. For example, if you want to set the valve to 50% capacity, first turn the lower knob counterclockwise to the corresponding position, then turn the upper knob counterclockwise once – at this point the valve begins to close. When the valve has reached 50% openness, turn the lower knob clockwise to select the stop position.
It can also be operated using a handwheel; in case there are problems with electric operation, emergency operation via the handwheel is possible. After all, electric valves are chosen precisely because it’s not easy to switch them on and off manually
This is an electric valve, right? It’s not a solenoid valve
The valve shown should be an electric valve equipped with a Rotork electric actuator; it can be controlled either from a control room or locally, and it will remain in its original position in the event of a power outage. On-site, it can be switched to manual wheel operation.
This is a Rotork electric actuator, not a solenoid valve. Instructions for operation are also provided on the second floor; you can refer to the actuator’s manual. I’m not sure what model it is – some versions come with a remote control. Based on your question, when the motor is powered on, it can be switched on/off automatically or stopped in the middle position; it can also be switched manually to a handwheel operation. Even if the motor loses power after this switch, it can still be operated manually.
This is an electric actuator; how could it be a solenoid valve? :L
This is an electric valve actuator; it remains in its original position when power is off, and it won’t move if not operated after power is restored
