The Bosch Rexroth MK15G1X/V/12 (R900385474) is a meticulously designed throttle check valve that ensures precise control over hydraulic fluid flow in industrial applications. This valve operates based on pressure and viscosity, providing reliable performance in a variety of settings. When fluid flows in the throttling direction, a spring mechanism and the hydraulic pressure force the poppet against the seat, effectively blocking the connection. The fluid is then channeled through lateral bores to a throttling point between the valve housing and an adjustable sleeve. Conversely, when the flow direction is reversed, pressure on the poppet's front face lifts it from the seat, allowing free flow without any throttling. This design feature also facilitates self-cleaning by enabling a portion of the fluid to pass through an annular gap during operation. The MK15G1X/V/12 valve is specifically engineered for pipeline installation and offers robust performance even under varying pressure and viscosity conditions. It allows for throttling in one direction while ensuring free flow in the opposite direction, optimizing system efficiency. Additionally, it boasts a corrosion-protected design that extends its lifespan even in harsh environments. This model comes from component series X and can withstand a maximum operating pressure of up to 315 bar while handling maximum flow rates as stipulated by Bosch Rexroth's specifications for this particular size component. The MK15G1X/V/12 valve exemplifies Bosch Rexroth's commitment to engineering excellence, offering users dependable control over their hydraulic systems with its advanced features and robust construction.

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.
