Product usage precautions

1. Avoid resonance with the system.

2. When used together with a pulsation damper, the pulsation damper should be installed between the pump and the back pressure valve to absorb the peak flow between the pump and the back pressure valve. Reduce the wear rate of the back pressure valve.

3. Outdoor use should be equipped with protective shelters or covers.

Before any maintenance is carried out on the back pressure valve, the equipment should be stopped, the pressure should be released, the valves connected to the back pressure valve and the system should be closed, and it should be confirmed that there is no pressure inside the pulsation damper. During maintenance, pay attention to preventing harm to the human body caused by the transported liquid.
