Summarize

BEIER electric actuated cooling water control valve is called cavitation erosion resistant, high pressure drops, low noise regulating valve, content to big capacity, high parameter trend of electric power station and battery of boiler, high sealing, serviced for full automatic electric power station.

This valve carry out the enterprise standard Q/IPPY3-1999.

Application range:

Electric actuated cooling water control valve is fixed in the boiler feedwater system, for regulating the temperature of feedwater.

It's served for high pressure drops,little flow,allowed pressure drops is 16-18Mpa,flow is no other than 3t/h,serious bad service.

Electric actuated cooling water control valve is automatic regulating valve, which have throttle ring with special labyrinth structure,with feature of zero leakage,low noise,cavitation resistant and great regulating capability,can be beard the control of little flow in high pressure drops.

Main parameter:

Nominal diameter: 20、25、32、50mm
Nominal pressure: 25、32 Mpa
Operating temperature: ≤252℃
Rated flow: 1-50t/h
Flow characteristic: Equal percentage

Structure:

The throttle part of lectric actuated cooling water control valve is composed of seat,plug,throttle ring and even flow cover.

Throttle ring is composed of several piece of drilled ring, each of ring have one-time pressure reduction function. and seat, even flow cover have one-time pressure reduction, the whole valve’s inner could reach more than ten-time pressure reduction, so it's able to endure high pressure drops, and it's not happened of cavitation.

Plug have balance structure, so little driving moment, valve can be open or shut off, just need to operate small electronic motor actuator.

Plug have balance structure, so little driving moment, valve can be open or shut off, just need to operate small electronic motor actuator.
Plug and seat’s surface is bead welding hard alloy, to guarantee valve have a long service term.

  Appearance and Size:

Please support technology parameter for special specification requirement, we will designed to service you.

Use Effect:

Electric actuated cooling water control valve, because has used the labyrinth type structure throttle ring, specially is suitable for the small current capacity, the high differential pressure bad operating mode. Can effectively avoid occurring the cavitation.The noise is low. The rating curve selects the equal percentage characteristic curve. And carries on the revision after the theoretical calculation, causes it to suit in the actual use process the request.

The effective automatic control, to enhances the unit hot economic efficiency, reduces the energy consumption, the effect is obvious, its structure pattern and the performance has achieved the international at the beginning of 90's the similar product level. Definitely may substitute the import.
