Butterfly valve installation precautions

Installation environment: Butterfly valves can be used indoors or outdoors, but in corrosive media and rust-prone occasions, the corresponding material combination should be used. For special conditions, please consult Zhongzhi Valve.

Installation location: It must be installed in a location that can be operated safely and is easy to maintain, inspect and repair.

Ambient environment: temperature -20℃~+70℃, humidity below 90%RH. Before installation, check whether the valve meets the operating conditions and use requirements according to the nameplate mark on the valve. Note: The butterfly valve does not have the ability to resist high pressure difference. Do not let the butterfly valve open or continue to circulate under the high pressure difference.

Before installation, please remove dirt and oxide scale from the pipeline. When installing, please note that the flow direction of the medium should be consistent with the flow direction arrow marked on the valve body.

Align the center of the front and back piping, make the flange connections parallel, and tighten the screws evenly. Pay attention to the pneumatic butterfly valve without excessive piping stress on the cylinder control valve. According to the size and weight of the cylinder control valve, provide proper support and fixation on the piping or on the body.

Maintenance precautions

Daily inspection: Check for leaks, abnormal noise, vibration, etc.

Periodic inspection: Check valves and other system components for leaks, rust and jams, and maintain, clean and remove dust, and remove residues.

Decomposition inspection: The valve should be decomposed and overhauled regularly. During the decomposition and overhaul, the parts should be washed again, foreign objects, stains and rust spots should be removed, damaged or worn gaskets and packings should be replaced, and the sealing surface should be corrected. After the overhaul, the valve should be subjected to a water pressure test again. , It can be reused after being qualified.

If fluid leakage is found during the inspection of the pneumatic butterfly valve, please do not touch or approach the cylinder control valve with your hands until safety is confirmed.
