The 400X flow control valves is a multifunctional valves that adopts the mode of flow control employed by high-precision pilot valves.
It is suitable for use in water distribution pipes within which the flow and pressure need to be controlled,
and can serve to keep the preset flow constant, restrict excessive flow at a preset value and reduce
the excessively high pressure upstream properly. This valves differs from other conventional throttle
valves, which normally work through reducing the flow area by means of orifice plates or purely
mechanically, by making use of an appropriate pilot valves to minimize the loss of energy in the course
of flow regulation. The 400X flow control valves can completely stop the flow in case of an emergency
to avoid loss.Accordingly, it boasts high control sensitivity and is reliable, safe, simple to debug and
offers a long service life.Pressure Rating: PN10. PN16. PN25/Class150Size Range: DN20mm-
DN800mm (3/4" - 32")Test and inspection: GB/T 13927 API598

The valves limits the flow rate in the pipeline to a preset rate, regardless of upstream pressure variations.
The valves is controlled by pilot valves, which takes use of integrated orifice plate to detect flow rate
represented by differential pressure, and the differential pressure is used to control the pilot valves to
implement flow rate control.
