The Bosch Rexroth Z1FG6P8-4X/M (R901268164) is a throttle valve designed for precise flow limitation in hydraulic systems. This sandwich plate valve, part of the ZFG series, is specifically engineered to regulate the flow in channel P by utilizing a control edge and an adjustable throttle spool. The throttle spool can be finely tuned via a spindle, allowing operators to set the desired flow rate through the throttling point. The adjustment stroke of the spindle is securely limited in both directions by a pin, ensuring consistent and reliable operation. The Z1FG6P8-4X/M valve boasts compatibility with ISO porting patterns and includes a locating hole for easy installation. It is designed to be mounted between components or onto a plate side, providing flexibility for system integration. This model offers an adjustment type that features a spindle with a hexagon socket, making adjustments straightforward with standard tools. With its robust design, the Z1FG6P8-4X/M can handle maximum operating pressures up to bar levels and accommodate maximum flow rates measured in liters per minute (l/min). The performance of this valve will vary based on the pressure differential across it as well as the viscosity of the hydraulic fluid being used. Its size and component series X designation ensure that it fits within a broad range of industrial applications where precise flow control is essential. Engineered for durability and precision, the Bosch Rexroth Z1FG6P8-4X/M throttle valve is an essential component for systems requiring reliable flow limitation capabilities.
The valve type Z1FG is a throttle valve in sandwich plate design. It serves for flow limitation in channel P.
In case of throttling, the hydraulic fluid is directed through channel P1 via throttling point (1) formed by the control edge (2) and the throttle spool (3) to port P2. The throttle spool (3) can be axially adjusted via the spindle (4) for adjustment of the flow via the throttling point (1). The adjustment stroke is limited by the pin (5) in both directions. The flow depends on the pressure differential and viscosity.
