The Bosch Rexroth MG8G1X/V (R900438885) is a high-performance industrial hydraulic valve designed for reliable flow limitation at selected ports to a predetermined setting value. This direct-actuated seat valve falls under the component series X and features a spool symbol A B, indicating its specific flow pattern. It is capable of handling a maximum pressure, although the exact value is not specified here. With its threaded connection type, this valve offers ease of installation and maintenance. It is mechanically actuated, which ensures consistent performance in various industrial applications. The MG8G1X/V valve is equipped to manage a max flow rate, and its design includes a number of ports for versatile connectivity options. The weight of the valve indicates its robustness and suitability for pipeline installation in demanding environments. Furthermore, it utilizes FKM seals which are known for their chemical resistance and durability across a wide range of temperatures. This makes it compatible with an array of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, HFDR. The MG series valves are characterized by their pressure and viscosity-dependent throttle capabilities which enable throttling in both directions of flow. The hydraulic fluid's path to the throttling point involves lateral bores that lead to an adjustable sleeve housed within the unit; by rotating this sleeve the user can seamlessly adjust the cross-section at the throttling point for precise control. Designed with corrosion protection in mind, this Bosch Rexroth valve ensures longevity even in harsh working conditions. Its size and series designation reflect its capacity to integrate into various industrial systems where precise flow regulation is critical.

Size 8, A → B, mechanically actuated

Industrial hydraulic valve in a high performance range. Reliable flow limitation at selected ports to setting value.

Unpacked Weight: 0.34 kg

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.
