Description

GVK’s Model GL Series is designed with a raditional Globe type flow path structure with a high 'pressure recovery coefficient(FL factor)'.Depending on the body structure, it is divided into 2-way, 3-way, and angle, Y-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

Features
  • Globe style with high FL factor and flow paths with streamlined structure
  • Top entry structure that can be applied to Contoured, Cage-balance, Pilot, and Disk Stact trim in metal and soft seat
  • Various Rated Cvs and Customized Rated Cv can be applied to implement the. desired openning plan of the customer according to the special specifications
  • In addition to basic EQ-%, Linear, and Quick Open flow characteristics, Customized Flow Characters can be applied to implement the desired flow characteristics of customers
  • Customized valve can be manufactured to improve specific weakness of existing same type valve
  • Applicable to the latest smart positioners as well as traditional P/P and E/P positioners with other instruments
