For pipeline installation
Related to pressure and viscosity
Throttling in both directions of flow
Corrosion-protected design
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.
