Cascade throttling control valve (Model TYP920)

TYP920 is one kind of multistage throttle valve of air defense, suitable for power plant boiler bypass small feed water flow control valve, reducing water regulator medium, harsh working conditions, such it is a key regulator of plant. Is also often used in the chemical industry control high pressure saturated liquid will flow.

TYP920Performance characteristics:

1. Resistance to cavitation, flashing, cavitation resistance, corrosion resistance, resistance to erosion

2. Multistage throttle, level 3, level 4, 5, 7, throttling

3. Balanced valve core, valve dynamic stability is good

4. Ultra high strength material HRC70

5. Body for forged steel,internal parts for high strength heat resistant stainless steel,The body can be straight, Angle type, Z type

6. Open valve core, 2-3 mm welding slag, etc solid particles will not jammed

7. Low leakage of filler

8. High temperature and high pressure

9. The spring diaphragm type/Piston type/Electric actuators

10. Advanced digital positioning and control techniques

11. Convenient maintenance

12. Size:DN25-500mm

13. Nominal pressure:PN10-PN42Mpa

Mainly used for power plant, the following conditions:

1.Feed water pump minimum flow control valve 2.Reducing water control valve 3.The boiler continuous blowdown control valve 4.The boiler blow gray pressure valve/ Reheater of air vent valve 5.High and low pressure bypass control valve 6.In addition to the oxygen level control valve 7.The steam pressure reducing valve 8.Boiler feed water control valve 9.Supercritical unit feed water control valve
