GYL40800 series balanced labyrinth control valve

Product Information:

The L-40800 adopts a labyrinthine path cage with a balanced trim design which is composed of multiple cylindrical discs (layers) with labyrinthine diameters distributed on the coaxial surface. According to the different mediums multiple different labyrinth diameter specifications and stacked layer arrays are designed to synthesize the valve cage. The valve cage divides the total flow path into many small circuitous or even stepped distribution throttling channels forcing the fluid to continuously change its flow direction and flow area gradually reducing the fluid pressure to prevent flash evaporation and cavitation and prolong the service life of valve internals. This trim structure is suitable for various process fluid conditions that are prone to blockage flow and corrosion.
The balanced trim can select with:
1. Cage single-seat type (High leakage class small working temperature range)
2. Cage double-seat type (low leakage class big working temperature range)
