Valve Installation Environment: Butterfly valves can be used both indoors and outdoors. However, in environments with corrosive media or prone to rust, appropriate material combinations should be used. For special operating conditions, please consult Zhongzhi Valve.

Installation Location: Installed in locations that are safe for operation, easy to maintain, inspect, and repair.

Surrounding Conditions: Temperature -20℃ to +70℃, humidity below 90% RH. Before installation, it is essential to first check the valve's identification plate to ensure the valve meets the operational requirements. Note: Butterfly valves do not have the ability to withstand high pressure differences; do not open or keep the butterfly valve in operation under high pressure differences.

Before installation, please remove any dirt and oxidation scale from the pipeline. During installation, ensure that the medium flow direction aligns with the arrow indicated on the valve body.

Align the front and rear piping centers, ensuring the flange interfaces are parallel, and evenly tighten the screws. Pay attention to prevent excessive piping stress from occurring on the cylinder control valve for the pneumatic butterfly valve.

Maintenance Precautions

Routine Inspections: Check for leaks, abnormal noises, vibrations, etc.

Regular Inspections: Regularly check for leaks, rust, and jamming in valves and other system components, and perform maintenance, cleaning, dust removal, and stain removal as needed.

Decommission Inspection: Valves should undergo a decommission inspection on a regular basis. During the inspection, parts should be re-rinsed, foreign objects, stains, and rust removed, damaged or severely worn gaskets and packing replaced, and sealing surfaces corrected. After the inspection, the valve must be re-tested with hydrostatic pressure, and only upon passing the test can it be reused.
