Overview of contents Contents Page Features, function, section, symbol 1 Ordering details, technical data 2 Characteristic curves 3, Unit dimensions Features For subplate mounting, For threaded connections, for manifold mounting, Lockable rotary knob. Function Flow control valves, type F are fine throttle valves with an orifice type throttle. They basically comprise of a housing (1), adjustment element (2) and orifice (3). They are used to throttle a flow almost independently of temperature variations. Throttling of a flow from to is carried out at the orifice aperture (). The throttle opening is adjusted by rotating the cylindrical pin (). The low dependence on temperature is due to the throttle area being designed as an orifice. 02 by osch Rexroth G, Industrial Hydraulics, D-13 Lohr am Main ll rights reserved.
