GC320 Labytinth Velocity Control Valve

This is multi-stage pressure reducing cage guided control valve. This series have a full control flow velocity so it can greatly reduce the noise generated by gas or steam with high pressure difference and preventing liquid cavitation. It is a type of high performance control valve with no cavitation damage, low noise, good control of fluid stability.

Performance Characteristics   

1、Labyrinth velocity control valve is an extended application of regular cage control valve, and it is designed based on a series of multi-stage pressure reducing principle.
2、The pressure difference of high pressure flow are reduced step by step after several expansion when the flow go through the plug and cage holes due to a number of multilevel window hole in certain shape on the cage. This achieves a whole control of the flow velocity, so the noise generated by the high-pressure gas or steam can be greatly reduced.
3、This valve can prevent fluid cavitation effectively as well as reducing noise. It is a type of high performance control valve with no cavitation damage, low noise, good control of fluid stability.

Product Advantage   

1、Cavitation, flash, vibration and noise are all caused by high flow velocity. Labyrinth velocity control valve has a good control of flow velocity and pressure so it can achieve anti-cavitation, anti-flash, low vibration and low noise.
2、This series can satisfy most high pressure difference control occasions by selecting the 1~24 step according to the actual situation.
