burkert 2861比例閥基于burkert 2871型改造的比例閥 Type 2861 is an extremely compact solenoid control valve and is available with an orifi ce up to 2mm. It is based on the standard version of Type 2871 (see datasheet). burkert 2861比例閥基于burkert 2871型改造的比例閥 It is used as an actuator in closed control loops (pressure, fl ow, temperature, etc.).  Compared with the standard version, the valve is essentially of simpler construction and assembly and testing procedures are optimized, easing high volume series production with shorter delivery times.  Please follow the instructions for a customised design on page 5 of this datasheet.
