adjustable pressure relief valve
YX741X adjustable pressure regulator valve
YA741X adjustable pressure
regulator valve is installed in the water supply and drainage system of
high-rise building pipeline, reducing the inlet pressure to a certain
outlet pressure of the special valve. The valve outlet pressure to
maintain their own energy set firmly in the plant, the outlet pressure
is not due to changes in inlet pressure and flow changes, and the inlet
valve control system is equipped with a self cleaning filter, exercise
body characteristics, the proportion of larger suspended particles of
larger diameter will not enter the control system, ensure the system of
circulation the valve can be unimpeded, safe and reliable operation. The
system is stable, high strength and long service life.
Pressure Relief Valve
Pressure Sustaining/Relief
Valve is a hydraulically operated, pilot-controlled, modulating valve
designed to maintain constant upstream pressure within close limits.
This valve can be used for pressure relief, pressure sustaining, back
pressure, or unloading functions in a by-pass system.
In operation,
the valve is actuated by line pressure through a pilot control system,
opening fast to maintain steady line pressure but closing gradually to
prevent surges. Operation is completely automatic and pressure settings
may be easily changed by adjusting screw on top of the pilot.
