Product Overview
The OLEOWEB STB140-20R is a precision-engineered hydraulic flow control valve from the OLEOWEB STB series, designed for accurate regulation of hydraulic fluid flow rates within industrial power circuits. This modular-style valve operates by throttling or diverting flow through a precision-machined spool and body assembly, enabling operators to set and maintain desired actuator speeds independent of load fluctuations. As a line-mounted or subplate-mounted component, the STB140-20R integrates seamlessly into modular hydraulic systems, providing reliable flow metering, pressure compensation, and directional control functions essential for demanding industrial machinery. Its robust construction and tight manufacturing tolerances make it a direct-fit replacement for OEM flow control valves in high-cycle hydraulic applications.
