The Bosch Rexroth 2FRM6A36-3X/3QMV (R900210721) is a high-performance industrial hydraulic valve designed for reliable control of fluid flow to a preset value. It features direct actuation with the closing of the pressure compensator and is equipped with a lockable rotary knob with scale for precise adjustments. This model does not include a check valve and is identified by its spool symbol A → B, B → A, indicating its flow direction capabilities. The 2FRM6A36-3X/3QMV valve is mechanically actuated, ensuring robust and consistent performance in various applications. With subplate mounting and connection diagram conforming to ISO standards, this valve integrates seamlessly into existing hydraulic systems. It boasts a maximum pressure capacity that ensures it can handle demanding operations without compromising on efficiency or safety. This unit's design includes several ports for comprehensive fluid control, although the exact number of ports is not specified here. The valve's size and max flow rate are tailored to meet the requirements of intricate hydraulic circuits while maintaining a steady flow rate regardless of pressure fluctuations or temperature changes. The seals are made from FKM material, offering excellent resistance to high temperatures and chemicals, thus ensuring longevity and reliability in harsh environments. The 2FRM6A36-3X/3QMV is compatible with a variety of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR types. Furthermore, this model’s weight contributes to its stability when installed but remains manageable for maintenance or reconfiguration purposes. The Bosch Rexroth 2FRM6A36-3X/3QMV represents precision engineering for industrial applications requiring meticulous flow control within their hydraulic systems.

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 (8).

Flow control valve type 2FRM 6 A…RV

(with external closing, with check valve)

In principle, the function of this valve is the same as that of valve type 2FRM 6 B…MV.

However, the flow control valve is provided with the possibility of an external closing of the pressure compensator (4) via channel P (9). The external pressure acting in channel P (9) via orifice (10), holds the pressure compensator (4) in closed position against the compression spring (6). When the connected directional valve (11) is switched over to permit flow from P to B, control is achieved as with type 2FRM 6 B. Thus, a start-up jump is avoided.

The version with pressure compensator closing can only be used for supply control.

The free return flow from channel B to channel A is directed via the check valve (8).

Attention!

The pressure loss of port P upstream of the directional valve to port A upstream of the flow control valve makes itself felt by a reduced flow.
