Labyrinth cage valve of series GC300 and AC300 of SCORE is the most effective and reliable control valve under high temperature, high pressure drop and other severe service. The specially designed flow path forces fluid through a tortuous path of right-angle turns, constantly changes its directions and impacts on the path, to control the pressure and kinetic energy letdown and limit the fluid velocity effectively. This kind of valve may effectively prevent cavitation for uncompressed fluid and may effectively reduce the noise of compressed fluid. Labyrinth valve may effectively prevent flushing and vibration of the valve trim.

Compared with “mixed path” design, “independent path” design may obtain more accurate mathematical model. SCORE holds complete mathematical model of labyrinth valve design and calculation, which enables SCORE to provide the most suitable solutions for customers based on severe service.
