Throttle (and Check) Modules TC1G -01 / 03 TC2G FLOW CONTROLS Hydraulic Fluids / Attachment / Instructions Hydraulic Fluids Fluid Types Any type of hydraulic fluids listed in the table below can be used. Petroleum base oils Synthetic fluids Use phosphate ester or polyol ester fluid. When phosphate ester fluid is used, prefix "F-" to the model number because the special seals (fluororubber) are required to be used. Water containing fluids Note: For use with hydraulic fluids other than those listed above, please consult your Yuken representatives in advance. Recommended Viscosity and Oil Temperatures...

FLOW CONTROLS Threaded Connections / Sub-plate Mounting Specifications / Model Number Designation Up to 21 MPa (3050 PSI), 200 L/min (52.8 U.S.GPM) These valves are available either with or without an integral check valve which allows free reverse flow. Flow rate through the valve is regulated by the movement of the spool, which is operated by a cam. When the spool is depressed, the flow is decreased in Normally Open type valves and increased in Normally Closed type valves. Their principal use is to control the speed of actuators in machine tools and similar applications. Normally Open Type Normally...
