Product Features

●For high-rise buildings, a reduction valve should be used on the bottom branch.

●The, motor housing should prevent water from seeping in. So when the valve is installed, the actuator must not be under the pipe.

●When the valve is mounted on a vertical pipe, the motor housing must be protected from dripping.

●Manual lever; When the manual lever is slowly,moved along the arrow and pressed into the notch, the valve is normally open. Whenever the current passes through the motorized valve for the first time, the manual lever is reset to the automatic position.

●If the actuator is not pre-installed on the valve body, when installing, first push the operating lever along the arrow direction into the lower groove, press the black button on the drive, put it on the valve body and release it, then it can be installed. Repeat the above steps if you need to disassemble.

●Note: The direction of water flow should be the same as the arrow on the valve body; the actuator should not be used as the fulcrum of force during installation.
