Hydraulic Control Pressure Reducing Valves DN100 PN16 With Double Gauge

Hydraulic Control Pressure Redusing Valve DN100 PN16 With Double Gauge

 

 

Brief introduction:

 

Streamlined body, combined floating-ball disc with cone-shape sealing surface,

 

these insure no abnormal vibration and noise when the valve is in use.

 

These can also reduce pressure loss, makes the scope of upstream pressure much wider than other pressure valves and pressure output more stable.

 

Widely used in potable water supply, building construction and so on.

Product Specification

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.
