Pressure sustaining valve is
utilized in the piping for users. It primarily matches up with
the minimum working pressure inside the tap water pipe and
maintains minimum standard working pressure at any point
inside the pipeline during peacetime and emergency.
Pressure relief valve is mainly for
sustaining safe water supply pressure in the pipe. When water
pump stops functioning or pipeline gate suddenly closes,
abnormal pressure forms inside the pipe. As the pressure gets
over a certain safety limit, pressure relief valve can open
automatically and releases the water pressure above the safety
limit, so as to ensure the safety of pipeline and equipment.
When the pressure turn back within the safety limit, the
pressure relief valve will close slowly.
Float Valve - When using float
valve, in order to save pool space and for easy maintenance,
the valve should be placed outside the pool, with the float
ball switch placing at the lowest point in pipeline,
consequently impurities deposit and cause to malfunction. It's
recommended that a filter should be installed to prevent pipe
blocking.
