Flow Control Modular Valve (Pressure and temperature compensated)

Transcription

1 v FLOW CONROL MOULR VLVE Flow Control (ressure and temperature compensated) Features to l/min,,ma C qhis modular valve is used to control actuator speed and for other flow control valve applications. w wide range of models are available for and port control, or port control, and port control. Specifications e pressure compensation mechanism ensures that the control flow rate does not change, even when there is pressure fluctuation. rhe control flow rate remains stable, even when oil temperature changes. tmaximum Operating ressure :,, Ma {,, kgf/cm } E F G H I J K L M N O Model OF-G-- OCF-G-W-X- OCF-G-W-Y- Nominal iameter (Size) / Maximum Working ressure Ma{kgf/cm } {} {} Control Flow Rate l/min. to (differential pressure: Ma{kgf/cm }). to (differential pressure:ma{kgf/cm }). to (differential pressure: Ma{kgf/cm }). to (differential pressure:ma{kgf/cm }). to (differential pressure: Ma{kgf/cm OF-G--J }). to (differential pressure:ma{kgf/cm }) OCF-G-W-X-J / {}. to (differential pressure: Ma{kgf/cm }) OCF-G-W-Y-J to (differential pressure:ma{kgf/cm }) OFH-G-W-X- OFH-G-W-Y- / {} Handling z For flow rate control, make sure that the pressure differential between the input port and output port is at least Ma {.kgf/cm }.

See pages - through - if these items are required. n series modular valves do not have an L (R ) drain port, so they cannot be used in combination with pressure center type solenoid valves (). m Flow rate fluctuation is ±% within the temperature range of C to C.
