Industrial hydraulic valve in a high performance range. Reliable control of the flow to setting value.
Unpacked Weight: 7.280 kg
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.

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) |
