Throttle/Check Valves, Inline | TCG/TC
The Hyloc TCG/TC series consists of inline, non-compensated throttle check valves designed to regulate flow in one direction while allowing free flow in the reverse direction. Featuring a conical throttling spool for precise, manual adjustment, these carbon steel or stainless steel valves are suited for hydraulic cylinder speed control in industrial and construction machinery.
- Operating Pressure : High Performance Range
- Application : Industrial & Mobile Systems
About this item
The Hyloc TCG/TC series refers to inline hydraulic throttle-check valves (also known as flow control valves with reverse free flow). These valves allow for precise, manual adjustment of hydraulic fluid flow in one direction while permitting unrestricted free flow in the opposite direction.
