The Z2FRM6AB2-2X/32QRV is manufactured by Bosch Rexroth within the Z2FRM 2-Way Flow Control Valves series for precise regulation of hydraulic actuators in automated machinery. Its nominal size of 6 defines the interface dimensions for NG6 subplates. A porting pattern in accordance with ISO 4401-03-02-0-05 allows direct mounting on standard manifolds. An integrated check valve permits free reverse flow while the metered direction remains controlled. Metering occurs through channel A, so designers can assign the regulated port unambiguously. The assembly withstands a maximum operating pressure of 315 bar for use in high-pressure circuits. Maximum flow is limited to 32 l/min, establishing the upper speed of connected actuators. A minimum flow of 250 cm³/min keeps control stable when system demand is low.
Flow is set with an internal adjustment screw that accepts a 3 mm hex key and uses an internal hexagon head to discourage accidental changes. The valve needs an 18 bar pressure differential at full flow to keep the regulating spool within its control range. Pressure stability remains within ±3 % of maximum flow, holding actuator velocity steady under varying loads. FKM seals provide compatibility with common hydraulic oils and elevated temperatures. Cleanliness class ISO 4406 20/18/15 limits particle contamination to prevent wear and sticking. Installation in any position simplifies manifold layout and hose routing. The absence of a locating hole lets the body sit flush on the subplate without alignment pins. A weight of 1.3 kg allows one-person handling during maintenance or replacement.
