Description
Technical Specifications
SPECS Multi hole Cage Guided Control Valves that meet low noise and anti-cavitation requirements by incorporating a multi-hole type cages, instead of the standard cages, in the cage guided Control Valves. All the parts except the multi-hole cage are interchangeable with the parts of the cage guided Series accordingly. For those severe fluid conditions that cannot be covered by this Series, please select Specs Valve multi stage type control valves.
Note:This series can not been used in the medium contains large solid particles.

Design Features
1. Besides the characteristics of ordinary cage guided valve, multi-hole cage guided control valve is with a big advantage of reducing noise and this is especially suitable for steam evacuation applications.
Benefits
1. The velocity of fluid with big pressure difference makes serious erosion to valve parts and lots of noise. The multi-hole cage has well solved this problem. For a fluid flow from up to down, the velocity is reduced when the flow colliding in the multi-hole cage and flow energy is reduced. For a gas flow from down to up, there is a volume expansion when the gas goes through the multi-hole cage, then this would reduce the gas pressure and the velocity would be reduced.
2. The multi-hole cage and the standard cage are interchangeable, and the other valve parts are in common use. This can optimize the resource, reduce inventory and shorten delivery time.
