Ventilation Butterfly Valve Precautions for Ventilation Butterfly Valve Manufacturers to Process Ventilation Butterfly Valve

r Tianrun Environmental Protection specializes in the production of ventilation butterfly valves, which are made of the same material as the valve body and processed into sealing rings. The applicable temperature depends on the material selection of the valve body and the nominal pressure

Let me tell you some precautions during the installation process of the ventilation butterfly valve
b
The height of the installation position, the inlet and outlet directions must meet the design requirements, and note that the direction of the medium flow should be consistent with the design requirements. The arrows marked on the valve body are in the same direction, and the connection should be firm and tight. br b

The ventilation butterfly valve must be visually inspected before installation. The valve nameplate should comply with the current national standard "General Valve Marking" br
.
b
For valves whose working pressure is greater than br b
and which have a cutting function on the main pipe, strength and tight performance tests should be carried out before installation, and they can only be used after passing the test.
b
During the strength test, the test pressure shall be br b
times the nominal pressure, and the duration shall not be less than br b
. The valve shell packing shall be qualified if there is no leakage. During the tightness test, the test pressure shall be br b
times the nominal pressure and the test duration shall meet the requirements.
