*Warning: Handle Set Screw is factory calibrated and should not be adjusted in order to defend the F and X stem from being harmed
Ball valve handle
provides rapid shut off while keeping the
metering flow presetting.
Encapsulated ball stem design has virtually no dead space to minimize system contamination.
Double O-ring sealing ensures perfect repeatable leak tight operation.
Lock set screw helps determine the required flow.
Factory calibrated set screw 
provides the 'mechanical 
stop' for step tip protection. 
Innovative and Patented flow path provided the ability to combine the Ball-Metering design.
Stem diffusion surface hardening provides the best galling resistance and protection from wear and corrosion.
