Product Details

ZXPII/ZXMII  series Low Noise Cage Guided Control Valve, cage guided, owning single seat, perforated cage and seat, high performance non-metallic seal ring and pressure balanced trim, is characterized by two stage pressure and noise reduction, large allowable shut pressure drops, good anti-cavitation and obvious noise reduction capability etc. The valve can be applicable in harsh services which have big noise and serious cavitation etc


Characteristics:

1.Multi-stage labyrinth cage

2.Using the materials with high hardness

3.Excellent performace of  Anti-cavication,anti-erosion,low noise

4.Applied for high differencial pressure conditions

5.Effectively control the fluid velocity

Actuator

Adopting rolling type diaphragm design technology, rolling bending replaces the traditional centralized bending, which greatly increases the life span of the diaphragm.
Combination of concave diaphragm with high strength plate, it has characteristics of good shape retention,diaphragm area constant and stable output.


Cage guided

The special design of the cage can help reduce the noise and pressure. characterized by super dynamic stability, large allowable on-off pressure differential and smaller thrust force. It is suitable for harsh working condition
