Multi-Function Electric Actuator butterfly check valve:
Feature:
The butterfly check valve is suitable for the pump station in industrial and water
treatment project, being installed into the output end of the pump to
achieve close and slowly close functions.
1. Size: 12" ~80"
2. Pressure: Class150, PN16
3. Temperature: ≤ 150° C

The valve works together with the pump upon requirements of the
pump station. When the pump starts, the electrical actuator will
drive the valve slowly open in accordance with the set voltage.
When the pump stops, pressing the preset program to close the
valve carries out the functions of 4 phases of valve close, which
include electric quick close, hydrostatic fast close, hydrostatic damping
slow close and hydrostatic damping delaying close.
The closing angle and time at each phase can be adjusted to achieve the best
performance of silent open or close according to needs, to protect
the safty of the pump and the pipeline system.

The valve adopts splitted shaft structure, streamline spherical disc
is applied to DN600, truss style disc to DN700 as well. The valve is
of rigidity, larger stream surface and samller flow resistance,
belonged to the conservation of energy product.

The valve uses the tilted Butterfly Disc sealing design, which
makes the opening or closing angle decrease, reduces the
pressure of water hammer and strengthens the regulating ability of
the valve.

The valve not only posseses the function of slow close check
valve, not also has the function of stop valve. It integrates the
functions of two kinds of valves, saving the pump station space and
makes better configure for pipeline system.

When the accident happens power off, the valve can be
automatically out of electric actuator and finishes the actions of
hydrastic quick close, hydrostatic damping slow close, hydrastic
damping delaying close to protect the safety of the pump station.

The valve adopts PLC control, it is suitable for the computer
integral control of the pump station. The valve is equiped with
electric control box on spot, it can be manually operated with
opening or closing, this way will make the maintenance, the
adjustment and the operation in case of accident conveniently.
