The Bosch Rexroth 2FRM6B36-3X/16QMV (R900205510) is a high-performance industrial hydraulic valve designed for precise flow control in a variety of applications. This direct-actuated valve features a lockable rotary knob with scale, allowing for reliable adjustment to the desired setting value without the need for a check valve. It operates without closing off the pressure compensator, ensuring consistent performance. The 2FRM6B36-3X/16QMV is mechanically actuated and offers smooth operation from port A to B and B to A. It is designed for subplate mounting and conforms to NFPA T.. R D and ISO standards regarding connection diagrams, with CETOP D size specifications. The valve has multiple ports, offering flexibility in system integration. With its robust design, the valve can handle a maximum pressure as specified by the product group ID, while delivering a maximum flow rate as indicated by its specifications. Its weight and dimensions are optimized for industrial use, ensuring it can fit within various system configurations. The hydraulic fluid compatibility of this model is extensive, supporting fluids such as HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. It also features FKM seals which provide excellent resistance against high temperatures and chemical degradation. This flow control valve is particularly useful when maintaining a constant flow regardless of pressure fluctuations or temperature variations is critical. By integrating this valve into hydraulic systems where precision is paramount—such as in manufacturing or processing equipment—operators can achieve superior control over their machinery's hydraulic functions. The 2FRM6B36-3X/16QMV stands out for its reliability and versatility in industrial settings where dependable flow regulation is required.

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.
