Description
Safety valve, as the best device for extra-pressure protection,
will automatically open and fully discharge to protect the
equipment pressure from going on rise when medium`s pressure rises
over the allowed valve and will automatically close when the
pressure lowers to the setting valve.The valve conforms with
GB/T12243-89 on its design, manufacture and acceptance etc.
Technical standards.
The bonnet of the sealed safety valve is enclosed in order to
protect dust and foreign matters from getting in and protect toxic
and combustible media from over-flow, while the opened boonet of
the open-type safety valve, which benefits to lower the
temperature inside of the spring chamber, is mainly used for the
pipeline and container with steam medium and the safety valve with
radiator is suitable for the medium with a temperature over 350℃.
For the safety valve with a lever, it can be opened manually with
the lever when the medium`s pressure is up to over 75% of that at
which the valve opens.
Full-bore safety valve`s height of opening ≥1/4 time the flow
diameter with a large amount of discharge, the height of opening
for a low-lift safety valve 1/20-1/40 time the flow diameter. Model CSV Series CSV4700 Spring Loaded Low Lift Type With Lever Safety Valve
