Profession manufactures hydraulic pressure Hydraulic cylinder, engineering Hydraulic cylinder  , is used for electricity liquid proportion control 's service Hydraulic cylinder, take the place of import REXROTH, ATOS service Hydraulic cylinder.
Electroforms liquid proportion control is point point electricity input signal modulate hydraulic pressure parameter (displacement, pressure, rate of flow) ,this are a kinds of ambition hydraulic pressures and electronic combinations, can be used for open ring and closed loop control system。As accomplishes to all sorts of sport proceed quick, stabilize and precise control.
Electroforms liquid proportion servo control's core is proportion servo valve, electronic amplifier according to input signal (ordinary for positive and negative 10VDC voltages or 0- -20mA currents) adjusts supply proportion electromagnetism ferrous current, electromagnet will be this current convert for act on valve core on 's strength, as overcomes spring strength, current's size parallel a proportion big and small strength, compresses spring bring forth a corresponding valve core displacement, changes valve 's open degree, reaches control rate of flow, pressure's aim.
