While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Bosch Rexroth directly.***
The Bosch Rexroth 2FRM10-3X/50LV (R900427776) is a high-performance industrial hydraulic valve designed for reliable control of flow to a set value. This direct-actuated valve does not include a pressure compensator but features stroke limitation and a lockable rotary knob with scale for precise adjustments. The spool symbol indicates A to B and B to A flow directions, ensuring versatility in application. Constructed for durability, this valve can withstand a maximum pressure as indicated by its product group ID, and it is equipped with multiple ports for connectivity. Mechanical actuation is employed for user control, while its size and max flow rate are specified to meet various system requirements. For installation, the 2FRM10-3X/50LV utilizes subplate mounting with connection diagrams conforming to ISO standards. The valve's design includes FKM seals compatible with an array of hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. Its way flow control valves serve to maintain a constant flow rate that is mostly independent of external factors like pressure and temperature variations. Bosch Rexroth's innovative orifice bush design ensures temperature independence at the throttling point. Additionally, the free return flow from channel B to A is managed via an integrated check valve. While regulated flow is unidirectional from A to B under standard conditions, the addition of a rectifier sandwich plate type ZS allows for bidirectional flow control suitable for oscillating flows. This model falls under component series X and has been engineered for maximum operating pressure (bar) and maximum flow (l/min) as defined in its specifications. The 2FRM10-3X/50LV's robust construction and flexible design make it an essential component in various hydraulic applications requiring precise flow management.

FLOW-CONTROL VALVE 2FRM10-3X/50LV

Size 10, A → B, B → A, mechanically actuated

Industrial hydraulic valve in a high performance range. Reliable control of the flow to setting value.

Unpacked Weight: 3.35 kg

For subplate mounting Porting pattern according to DIN 24340 form G and ISO 6263 Mechanical actuation Pressure compensator stroke limitation, optional Start-up jump reduction Flow control in both directions through rectifier sandwich plate

Flow control valves type 2FRM are 2-way flow control valves. They are used to maintain a constant flow, mostly independent of pressure and temperature.

Generally, the valves consist of housing (1), orifice bush (2), pressure compensator (3) with optional stroke limitation (3.1), check valve (4), adjustment element (5) at type 2FRM as well as geared piston drive (6), and directional valve (7). The flow from channel A to channel B is throttled at the throttling point (9). The throttle cross-section of type 2FRM is set by mechanically turning the curved bolt (10) over the adjustment element (5). The positioning velocity can be set by means of the throttle check valve (6.3 and 6.4). To fix the required adjustment range, the geared piston drive (6) is equipped with an adjustable stroke limitation (6.1 and 6.2) on both sides. An upstream pressure compensator (3) is included to ensure a pressure-independent and constant flow at throttling point (9).

Temperature independence is achieved thanks to the orifice design of the throttling point.

The free return flow from channel B to channel A is directed via the check valve (4).

The regulated flow only flows from channel A to B.

For oscillating flows (forward and return flow), a rectifier sandwich plate type Z4S can be installed under the flow control valve.
