The Bosch Rexroth 2FRM6A36-3X/02QRV (R900225234) is a high-performance industrial hydraulic valve designed for reliable control of fluid flow to a set value. This mechanically actuated valve features direct actuation and includes a pressure compensator that can be closed, as well as a lockable rotary knob with scale for precise adjustments. Additionally, it incorporates a check valve for unidirectional flow control. The 2FRM6A36-3X/02QRV valve is characterized by its spool symbol A ➔ B, B ➔ A and is suitable for maintaining constant flow regardless of pressure and temperature changes. The robust construction consists of a housing, rotary knob, orifice bush, and pressure compensator. An optional check valve can be included depending on the specific application requirements. This model offers an external closing of the pressure compensator via channel P, which enables the user to avoid startup jumps by holding the compensator closed against the compression spring through external pressure. This feature is particularly useful for supply control applications. Designed with subplate mounting and conforming to ISO connection diagrams, this valve ensures ease of integration into various hydraulic systems. The size specifications, maximum operating pressure, maximum flow rates, number of ports, type of actuation (mechanical), types of connections (subplate mounting), switching positions, weight specifications, and compatible seal materials (FKM) are all tailored to meet demanding industrial requirements. The hydraulic fluids compatible with this valve include HL, HLP, HLPD HVLP HVLPD HETG HEES HEPG HFDU HFDR. Flow control valves like the 2FRM6A36-3X/02QRV are essential components in hydraulic systems where precise flow regulation is necessary to ensure optimal performance and efficiency in various mechanical processes.

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.
