L40800 using pressure balance type labyrinth cage joint design of Industrial Valves core, composed of multiple distributed the labyrinth of the cylindrical surface of the coaxial disk ( Layer) Composite component, depending on the medium parameters, design different labyrinth specifications and composite layer array synthesis of cage, the cage will total flow is divided into many small and circuitous step even distribution of throttling path, forcing fluid constantly change flow direction and flow area, gradually reduce the fluid pressure, to prevent flash, the occurrence of cavitation phenomenon, prolong the service life of trims. Within such a structure is suitable for all kinds of produces blocking the flow of the corrosion process conditions of the fluid.

balance labyrinth multi-stage decompression Industrial Valves

USES balanced internal parts can be selected:

1. Cage single-seat type ( Level of leakage of high temperature range is small)

2。 Cage type two-seater type ( Low leakage level using the wide temperature range)
