Product description
Flow control valves type 2FRH 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) as well as geared piston drive (6), directional valve (7) and actual value potentiometer (8) at type 2FRH. The flow from channel A to channel B is throttled at the throttling point (9). At type 2FRH, the throttle cross-section is set by means of a geared piston drive (6) controlled by an integrated electrically operated directional valve (7). 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).
For permanent monitoring of the throttle orifice position, type 2FRH can be equipped with an actual value potentiometer (8). In connection with an electrical command value presetting, electrical control components are offered.
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.

| Important information on hydraulic fluids! For further information and data on the use of other hydraulic fluids, please refer to data sheet 90220 or contact us! There may be limitations regarding the technical valve data (temperature, pressure range, life cycle, maintenance intervals, etc.)! The flash point of the hydraulic fluid used must be 40 K higher than the maximum solenoid surface temperature. Flame-resistant – containing water: Maximum pressure differential per control edge 50 bar. Pressure pre-loading at the tank port >20% of the pressure differential; otherwise, increased cavitation Life cycle compared to operation with mineral oil HL, HLP 50 to 100 % Bio-degradable: When using bio-degradable hydraulic fluids that are zinc-solving, zinc may accumulate in the fluid (700 mg zinc per pole tube) | ||||
