The Bosch Rexroth 2FRM6B36-3X/10QRV (R900205509) is a high-performance industrial hydraulic valve designed for reliable flow control to a set value. This valve features a mechanically actuated spool with A to B and B to A functionality, ensuring consistent flow regardless of pressure fluctuations. It comes with an integrated check valve and does not require closing of the pressure compensator. The 2FRM6B36-3X/10QRV is equipped with a lockable rotary knob that has a clear scale for precise adjustments. The housing, rotary knob, orifice bush, and pressure compensator are meticulously constructed to maintain a constant flow within the system, independent of external pressures and temperature changes. This valve operates without an external closing mechanism and does not include a check valve by default. The design incorporates a pressure compensator positioned downstream from the throttling point to ensure that the flow remains steady in channel B. The compression spring ensures that the compensator remains open under no-flow conditions, while fluid flow prompts the compensator to balance forces for consistent operation. For bidirectional flow control, an additional rectifier sandwich plate type ZS can be installed beneath this valve. The 2FRM6B36-3X/10QRV adheres to DIN form A for porting patterns and is available with optional adjustment types like rotary knobs with or without scale locking features. This model boasts compatibility with various hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR types. It has FKM seals that promote durability against these fluids. The subplate mounting design follows CETOP D standards and it connects according to NFPA T.. R D SizeCETOP D or ISO connection diagrams. With its robust construction and versatile capabilities, the Bosch Rexroth 2FRM6B36-3X/10QRV offers optimal performance for systems requiring precise hydraulic flow regulation.

General information

The flow control valve type 2 FRM is a 2-way flow control valve.

It is used for maintaining a constant flow, independent of pressure and temperature.

The valve basically consists of housing (1), rotary knob (2), orifice bush (3), pressure compensator (4) and an optional check valve.

 

Flow control valve type  2FRM 6 B…MV

(without external closing, without check valve)

The flow from channel A to channel B is throttled at the throttling point (5). The throttle cross-section is set by turning the rotary knob (2). To ensure a pressure-independent and constant flow in channel B, a pressure compensator (4) is fitted downstream of the throttling point (5).

The compression spring (6) presses the pressure compensator (4) downwards against its stop and keeps the pressure compensator (4) in the open position when there is no flow through the valve. When fluid flows through the valve, the pressure acting in channel A applies a force to the pressure compensator (4) via orifice (7).

The pressure compensator (4) moves into the controlled position until the forces balance. If the pressure in channel A rises, the pressure compensator (4) moves in the closing direction until the forces are balanced again. Due to this continuous compensation of the pressure compensator (4), a constant flow is obtained.

In order to control a flow through the valve in both directions, a rectifier sandwich plate type Z4S 6 may be fitted below this flow control valve.
