Description Size 10, 6 Component series 1X Maximum operating pressure 315 bar Maximum flow 60 l/min Features Cartridge valve Adjustment type with internal hexagon With integrated check valve Low start-up jump Product description The valve type 2FRM.K2 is a 2-way flow control valve for block design installation. It is used for pressure and temperature-independent flow stabilization. The valve basically consists of housing (1), adjustment type (2), throttling point (3), throttle bolt (4), pressure compensator (5) and check valve (6). The flow from channel A to channel B is throttled at the throttling point (3). The throttle cross-section is set by rotation of the adjustment type (2) between the throttling point (3) and the throttle bolt (4). For pressure-independent flow stabilization in channel B, a pressure compensator (5) is connected downstream to the throttling point (3). The pressure compensator (5) is pressed by the compression spring (7) against the plug screw (8) and remains in open position if there is no flow through the valve. When there is a flow through the valve, the pressure in channel A applies a force on the pressure compensator (5). It is set to control position until the forces are balanced. If the pressure in channel A rises, the pressure compensator (5) moves in closing direction until the forces are balanced again. Due to this continuous compensation of the pressure compensator, a constant flow is obtained. The free return flow from channel B to channel A is directed via the check valve (6).
