Description Size 6 … 30 Component series 1X Maximum operating pressure 315 bar Maximum flow 400 l/min Features For pipeline installation Related to pressure and viscosity Throttling in both directions of flow Corrosion-protected design Product description The valves type MG are pressure- and viscosity-dependent throttle valves. Throttling is realized in both directions of flow. The hydraulic fluid is directed to the throttling point (4) via lateral bores (3). It is formed between the housing (2) and the adjustable sleeve (1). By rotating the sleeve (1), the cross-section of the throttling point (4) can be steplessly adjusted.
