The Bosch Rexroth MK10G1X/V (R900424579) is a high-performance industrial hydraulic valve designed for reliable flow limitation at selected ports up to the setting value. This direct-actuated seat valve falls under Component series X and features a spool symbol for A B configuration. It is built to sustain a maximum operating pressure and offers precise control in hydraulic systems. The MK10G1X/V valve is mechanically actuated, ensuring robust operation and responsiveness in various applications. With its threaded connection type, it facilitates secure integration into pipelines, making it suitable for industrial environments where consistent performance is critical. The number of ports and switching positions are tailored to provide versatility while maintaining efficiency in fluid control tasks. This model is compatible with a wide range of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. The FKM seals within the valve contribute to its durability and suitability for use with diverse fluid types without compromising integrity. The design also includes self-cleaning features that ensure long-term reliability and reduced maintenance requirements. The MK10G1X/V valve's capability to throttle in one direction while allowing free flow in the opposite direction makes it an essential component for systems requiring unidirectional flow control. Its corrosion-protected design extends the life of the valve even in harsh operating conditions. The specified size along with the maximum flow rate measured in liters per minute (l/min) highlights its capacity to handle substantial flow rates efficiently. Overall, the Bosch Rexroth MK10G1X/V hydraulic valve is engineered for optimal performance in pipeline installations where pressure and viscosity-dependent throttle check functions are necessary. Its robust construction and compatibility with various fluids make it a reliable choice for industrial applications requiring precise flow regulation.

THROTTLE VALVE MK10G1X/V

Size 10, A → B, mechanically actuated

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

Unpacked Weight: 0.7 kg

For pipeline installation Related to pressure and viscosity Throttling in one direction of flow, free flow in opposite direction Corrosion-protected design

The valves type MK are pressure- and viscosity-dependent throttle check valves.

If the valve is passed by the flow in throttling direction, the spring (6) and the hydraulic fluid push the poppet (5) on the seat and the connection is blocked. Via lateral bores (3), the hydraulic fluid flow is directed to the throttling point (4) between the housing (2) and the adjustable sleeve (1).

In the opposite direction, the pressure acts on the front face of the poppet (5), lifts it from the seat and releases the flow. The hydraulic fluid flow is released through the valve without throttling.

In this process, simultaneous passing of a part of the hydraulic fluid via the annular gap leads to the desired effect of self-cleaning.
