The Bosch Rexroth Z1FG6P8-4X/V (R901170487) is a throttle valve designed for precise flow limitation within hydraulic systems. This sandwich plate valve, part of the ZFG series, is engineered to control fluid flow in channel P by utilizing a throttling point created between the control edge and the throttle spool. Users can finely tune the flow rate through this channel by adjusting the axial position of the throttle spool using a spindle mechanism. The adjustment stroke of the spindle is securely limited in both directions by a pin, ensuring stable operation within predefined limits. The Z1FG6P8-4X/V valve boasts compatibility with ISO porting patterns and includes a locating hole for ease of installation. It is designed to be mounted between components or onto a plate side, providing versatility for integration into various hydraulic circuits. The valve is equipped with a spindle featuring a hexagon socket for adjustments, allowing technicians to set desired flow rates accurately. This model from Bosch Rexroth supports maximum operating pressures up to X bar and can handle maximum flow rates of l/min, making it suitable for a wide range of applications that require reliable and consistent flow regulation. Its robust construction and precision engineering are indicative of Bosch Rexroth's commitment to quality in hydraulic system components. With its ability to limit flow in a controlled manner, the Z1FG6P8-4X/V valve is an essential part for systems where maintaining specific fluid dynamics is critical for optimal performance.
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.
