Globe Control Valve
Valution`s Model GL Series is designed with a traditional Globe type flow path structure with a high 'pressure recovery coefficient'(FL factor).
Depending on the body structure, it is divided into single-seated, double-seated, 3-way, and angle pattern.
Depending on the trim structure, there are Un-balanced types with a built-in Contoured Plug trim, Cage Balanced types with a built-in Cylinderical Plug trim, Multi Hole type trims, and Disk Stack trims with grid-shaped labyrinth flow path.
This model can implement EQ-%, Linear and Modified-% flow characteristics with a contoured plug and a cage window shape.
Since the body has streamlined and S-shaped structures, it has low fluid resistance and sufficient space around the trim.
This model can apply the Spring-diaphragm, Cylinder, and Electric Motor types of actuators.
The conventional E/P, Smart, and HART Positioners are applicable.
