additional actuation modules are not necessary. The motor’s power consumption to hold a speci? c opening position of the valve is zero.
This key feature can reduce the energy consumption of a plant dramatically and thus make it more e? cient.
Type 3285 is available as a standard ON/ OFF or proportional valve,
as a version with integrated positioner and as a version with integrated process controller.
? 2/2 way Proportional Valve (motor-driven)
直接作用式比例阀型号 3285 适用于在密封式或开放式调节回路中计量液体和气体。阀门通过步进电机驱动。
集成式电子装置显著简化了流程一体化，并且不需要使用额外的控制模块。夹持特定的阀门孔眼时，电机不需要能源。
这一特性可大幅度降低设备对能源的需求，从而使其更为高效。
