Frequently Asked Questions and Explanations
How should I handle the knob and thumbscrew on the top of the air vent valve body? (There is a video in the answer details)
Keep the knob and thumbscrew open during normal operation (fixed at the time of shipment). In the event of water leakage, the knob closes the plug. (After that, disassemble and repair immediately.)
What happens to the operation if the applicable pressure is exceeded?
It will be in an exhaust impossible state.
I would like to install an air vent valve on the suction side of the pump.
Use the AF-9 type when the suction side of the pump or other functions that only discharge air but do not suck air are required.
