Product Description
Hydraulic Control Slow Closing Non-return Butterfly Valve, Normally
named as Counterweight Butterfly Valve is one type of Advanced
Products used for management on Controlling Equipments. They are
widely used into the area of entrance of Turbine in Hydraulic Power
Station, or installed in the pump exit of irrigation, electric and
water treatment areas which can replace the functions of Gate valve
and Check Valve. When such product of Hydraulic Counterweight
Butterfly Valve is operated, this valve is matched together with
main pipeline systems, based on the principle of water pass
procedures, through the pre-set on/off procedures, effectively
derived the water hammer through the pipeline to realize the flow
cut-off and ensure a safety or protection function onto such
systems
Hydraulic Control Slow Closing Non-return Butterfly
Valve(Counterweight Butterfly Valve) from rechon vango valves are
with features of small flow co-efficiency, high automatic, complete
functions or devices, reliable performance which is one new high
auto-tech. energy saving products designed and produced based on
domestic/overseas similar areas covering valve, hydraulic and
electric industries. With profound knowledge in such products, we
rechon vango valve can also welcome customers’ OEM order upon
request to meet different areas requirement.
COUNTERWEIGHT BUTTERFLY VALVES ARE WITH FOLLOWING FEATURES
- This Type of Valve of Counterweight Butterfly Valve Can replace the
function of Gate Valve or Check Valve from entrance of water pump,
with a integral parts of Mechanical, electric and hydraulic a
uni-body which can reduce the landing area and base investment etc.
- With complete function of Both Electric and Hydraulic, there is no
need to equip other devices which can be used as a separate system
to debug and control at site, this valve can also be services as
one unit of system for DCS, managed by central computer through the
I/O to realize the united-operation by the water pump, turbine,
bypass valve and other pipeline equipments, moreover, this kind of
valve is also equipped with handwheel which can ensure that the
valve can be operated even without electric power to meet a special
debug and controlling requirements under a special work condition.
- With features of good performance controlling and Wide range of
adjustment, rechon vango hydraulic Counterweight Butterfly Valve
are with many regulators inside of the Hydrau-electric system which
can on/off the system set conforming to different pipelines’
requirements, by this way, not only make the valve meet the
requirement of on/off condition, further ensuring the valve can
(only) be opened at the pre-set time and angle, closed at the
pre-set separately and slowing 2nd stage. To realize the valve off
without power, effectively eliminated the water hammer and prevent
the accidents caused between water pump and turbine, reduce the
pressure fluctuation of pipe-network, ensuring a safety and
reliable operation of system equipment
- Main Sealing is with Secondary sealing of Triple-eccentric or
double-eccentric sealing structure which is easy on/off and
reliable in sealing. Further more; there is an extra enlarged
eccentric structure to ensure the Hydraulic Counterweight butterfly
valve is with perfect self-sealing function. Small and mid-sized
butterfly discs are designed with streamline plate structure, while
the big sized discs are with double plated york type structure with
small crush, smooth flow, valve co-efficiency is within 0.1~0.6
which is more smaller than the ones of check valves (1.7~2.6).
