The STB-G1/2 allows for precise adjustment of fluid volume in both directions. It features a non-pressure-compensated design, meaning the flow rate is determined by the pressure drop and the viscosity of the hydraulic oil. Built with a robust carbon steel body and protected by chrome or zinc plating, the valve is engineered for extreme industrial environments. Its internal components consist of tempered and ground steel, ensuring an excellent mechanical seal with negligible leakage. The valve is operated via a manual adjustment knob that includes a locking screw to maintain specific flow settings during operation.
