| Dalian
Hengli Measures & control instrument engineering limited |
|
| company
make great progress continuously in the design technique of |
| control
valve and flowmeter by using advanced design & develop |
| technique.
We research and develop high technique products such as |
| Labyrinth
multistage pressure reduction control valve, cage with holes |
| low
noise valve, shockproof valve and so on. We develop regular control |
| valve
at the same time. Our products already covered various Globe |
|
| Valves,
Butterfly Valves, the Ball Valves and other high level control |
| valves.
At the same time, We develop and manufacture various flowmeters |
| including
electromagnetism flowmeter, double turns, waist wheel |
| flowmeter,
Bar flowmeter and throttle device, volume tube mark device |
| etc.。 |

HL12241M
cage guide single seated low noise valve and |
| HL12241K
maze multilevel pressure reduce cage guide single |
| seated
globe valve-- |
| Due
to adoption of multi orifices and maze multilevel reducing |
| pressure
structure, air corrosion is avoided, also the flow |
| velocity
is effectively controlled. In addition, the noise for |
| control
valve operation under rigid working condition is greatly |
| reduced.
The service life and replace period for control valve is |
| prolonged.
This type of control valve can meet the requirements |
| of
high temperature, high pressure and high pressure |
| difference
in the complex working condition. |

| HL12215
Series anti-corrosion lining control valve-- |
| Using
much more gliding flow channel and special strengthen |
| plug
structure, it is applicable for controlling various kinds of |
| strong
corrosive medium. And it is much more economic than |
| metal
alloy anti-corrosion valve by adopting teflon liner, bellows |
| seal
and leakage detection structure. |

Vencore
flowmeter is a new type differential pressure |
| (DP)
flowmeter. It adopted to two kinds of differential |
| Primary
Elements (Venturi-Nozzle and Vencore) in structure |
| design.
It will become high precision multifunctional |
| differential
pressure flowmeter matched with |
| multivariable
transmitter. The measure for low velocity |
| of
flowrate become realization. High measure |
| precision(±0.2%),
wide range rate(30:1), no special |
| requirement
for straight pipe, low pressure loss, self- |
| cleaning
function, all this is the features. It is |
| suitable
for the mass or volume flow measurement of dirty |
| medium.
The medium can be water, steam, air, natural gas, |
| nitrogen,
coal gas and organic gas, etc. |

Vencorebar
flowmeter is a brand new structure
|
| differential
pressure (DP) flowmeter. It adopted to two |
| kinds
of differential throttle components (Venturi-Nozzle |
| and
Annubar) in structure design. It will become high |
| precision
multifunctional differential pressure flowmeter |
| matched
with multi parameter transmitter . |
The
measure for low speed flow become realization.
|
| High
measure precision(±0.75%), wide measure range |
| rate(20:1),
no special requirement for straight pipe, low |
| pressure
loss, self-cleaning function, these are all the |
| features.
It is suitable for the quality or volume flow |
| measurement
of dirty medium. The medium can be water, |
| steam,
air, natural gas, nitrogen, coal gas and organic |
| gas,
etc. |
