Unique Design of GEKO Instrument Valve

GEKO instrument valves have multiple configurations to choose from,

suitable for low and high pressure environments, and can achieve precise

flow control in analytical, instrumentation, and scientific applications.

In applications that require precise flow levels, they can be finely adjusted

with flow coefficients ranging from 0.004 to 0.16. There are various handle

options available for measuring valves, which can achieve repeatable flow

regulation, enhanced flow setting control, or use a screwdriver for flow setting

adjustment in low-pressure applications.
