2-ходовой клапан регулирования расхода 2FRM

Description Size 10, 16 Component series 3X Maximum operating pressure 315 bar Maximum flow 160 l/min Features For subplate mounting Porting pattern according to DIN 24340 form G and ISO 6263 Mechanical actuation Pressure compensator stroke limitation, optional Start-up jump reduction Flow control in both directions through rectifier sandwich plate Product description 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. Type 2 FRM...
