E 5.967.1.0/12.10
162
Flow Divider / Combiner
SAE 16-Cartridge – 350 bar
ST16-01
150 l/min
350 bar
In dividing mode, the ST16 will divert
input ow, according to the specied
ratio, from port 3 to ports 2 and 4.
In combining mode, input ow will be
combined, according to the specied
ratio, from ports 2 and 4 into port 3.
Port 1 is not used and should be
blanked.
Features
All surfaces zinc-plated and corrosion proof
All valve parts made of high-strength steel with hardened and ground
components to ensure minimal wear and to extend service life
Rigid design using one-piece body minimizes the effect of eccentricity
and maximizes reliability
High dividing & combining accuracy
Wide ow range down to 25% of nominal ow rating
Low pressure drop
Can be used for differential lock in transmission applications
Synchronizing ow in the dividing and combining mode in motor
and cylinder applications
Compact design
