Valve Seriers - Multi-functional Water Pump Control Valve Seriers
MULTI-FUNCTIONAL HYDRAULIC CONTROL VALVE
A.MULTI-FUNCTIONAL HYDRAULIC CONTROL VALVE About the Product
The motion performance of the valve is similar to that of the
hydraulic control valve. It utilizes the self pressure in the
pipeline and the pressure difference between the control room of
upper and lower cavities to control the movement of the main disc.
And it forms each series valve via the different functions of the
by-pass pipeline and the pilot valves of various different
structures so as to get to the target of various requirements.
A available with silencing/hammer removing/slow-open/slow-close
check valves, water level control valve, pressure reducing valve,
safety pressure relieving valve, electric remote control valve etc.
It is used in different conditions, ensuring safe running of the
pipe network automatically and suitable for the pipe network of
buildings, fire-fighting, water works, warming, steel and iron,
electric power, petroleum, chemical industry ect.
B.MULTI-FUNCTIONAL HYDRAULIC CONTROL VALVE FEATURES
- Slow-open function resolves the conventional problem for people to
close valve and open pump.
- Slow-close function is capable of adjusting the close time
artificially, realizing slow-close and removing water hammer
automatically.
- Good sealing performance and no one-drop of water leaks after being
closed.
- Sensitive, safe and reliable motion. Without any out-of-control
condition.
- No need artificial operations, during the complete process, all
automatic work makes the pipe network to run.
- Both outside and inside of the valve and all the easy corrosive
parts are coated with epoxy resin powder.
- Removable seat ring of an exquisite structure, easy repair and
replacement (no need to remove the whole valve).
- It is mountable on the pipeline vertically or horizontally, with
the unchanged reliability.

a. Diaphragm type
Use of different purposes can separate or make two cavities through
so as to realize slow-open, slow-close or quick-close auxiliary
functions etc. Preventing water hammers from being produced or
reduces its strength to a certain extent and protects the other
equipments after the valve from getting damaged. Besides, the
integrated bonnet and upper cavity make bonnet, upper cavity, stem
and dis
