Overview
2FRM6B76-32／6QMV,2FRM6A36-3X, Adjust the throttle opening and set the flow rate using the $r $n knob of the speed control valve. The $r $n $r $n pressure compensator automatically compensates for changes in load pressure and maintains a constant flow rate (stable within a pressure difference of 5-315 bar).

| 2FRM6A36‑3X/0.2QV | 0.2 L/min | Ke Wai Guan (A) | Nothing | FKM（V） | Small flow, precise fine-tuning |
| 2FRM6B36‑3X/1.5QV | 1.5 L/min | Cannot be closed externally (B) | Nothing | FKM（V） | Small and medium flow, universal speed regulation |
4、 Structure and Working Principle
composeValve body, scale knob, throttle valve core, pressure compensator, optional one-way valve.
Positive (A → B)：
Adjust the throttle opening with a knob and set the flow rate.
The pressure compensator automatically compensates for changes in load pressure and maintains a constant flow rate (stable within a pressure difference of 5-315 bar).
Reverse (B → A)：
beltMModel: When the one-way valve is open, the oil flows back freely without throttling.
withoutMModel: Reverse cut-off, requiring rectifier board (Z4S6) to achieve bidirectional speed regulation.
5、 Appearance and installation dimensions (2FRM6 series)
mounting surface4 holes, spacing 40mm x 40mm, oil port G1/4.
knob: With scale and lockable (optional).
baseplate: Must be ordered separately (models G67/01, etc.).
