Description Size 6 Component series 3X Maximum operating pressure 315 bar Maximum flow 32 l/min Features Porting pattern according to DIN 24340 form A Subplates (separate order) External closing of the pressure compensator Check valve, optional 2 adjustment types, optional: – Rotary knob with scale – Lockable rotary knob with scale Product description 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 (8). Flow control valve type 2FRM 6 A…RV ( with external closing, with check valve) In principle, the function of this valve is the same as that of valve type 2FRM 6 B…MV. However, the flow control valve is provided with the possibility of an external closing of the pressure compensator (4) via channel P (9). The external pressure acting in channel P (9) via orifice (10), holds the pressure compensator (4) in closed position against the compression spring (6). When the connected directional valve (11) is switched over to permit flow from P to B, control is achieved as with type 2FRM 6 B. Thus, a start-up jump is avoided. The version with pressure compensator closing can only be used for supply control. The free return flow from channel B to channel A is directed via the check valve (8). Attention! The pressure loss of port P upstream of the directional valve to port A upstream of the flow control valve makes itself felt by a reduced flow.
