Multi-Level Maze Regulating Valve

N2000 high-pressure adjusting valve series use advanced multi-level pressure relief
designing concept. It can limit the fluid at lower speed. This structure not
only eliminates liquid medium gas piping phenomenon, but also divides the critical
fluid pressure into many, which can avoid the emergence of noisy operation phenomenon
and ensure regulating valves to make a smooth, non-gas piping work in a
bad working situation. The wide range of products can be applied to power plants,
petrochemical, gas high differential pressures liquids, gases and steam occasions.
The series valves may require user configuration of electrical, pneumatic
enforcement agencies.

Main products:
1) N2100 multi-level cascade regulating valves series
2) N2200 multi-level maze regulating valves series

Main features:
1) Resolve compressed and uncompressed fluid existing problem
2) Prevent the gas piping and air-based phenomena
3) Prevent the mechanical vibration and uncertainties in "X-Y-Z" 3 directions
4) N2100 series prevents the possibility of rubbish in pipeline to block pipeline
score,
    the fluid contains 2-3m soldering rubbish will not block the pipeline
5) Control the outflow of fluid to less than 30m/s
6) Separate throttling and sealing block surface in order to prevent sealing surface
    from damaging and eroding
7) After hardened dealing with surface valves, rigidity degree could reach HRC70
with
    tight closure and last for life long
8) The surface shape design of valve score can meet the demand of adjusting apex
in
    the high and low apex time
9) The surface shape design of valve score ensures the flow curve of adjusting valve
    meet the demand of IEC534 and controlling system
10) N2100 series divide flow pressure structure into seven level, ten level, thirteen
    level and sixteen level, while N2200 series divide flow pressure structure into
ten
    level, eighteen level, twenty-six level, thirty-four level and forty-two level
11) This can be applied to different releasing pressure demand for different fluids
12) Flange distance: consistent with ANSI/ISA standards
13) Noise level: <85dBA
14) Parts of valves can be changed in spot and are more reliable

N2200 series have unique maze pillar design, achieve multilevel-relief process, while
fluids are forced when flowing into the maze, and the speed is limited. So
that the lower body of scope can regulate smoothly, without gas eroding and  working
 in the dirt poor state of pieces. The series valves may be confabulated of
electrical, pneumatic enforcement agencies by the requirement of the users.
