    INTRODUCTION stroke in proportion to control pressure. Full stroke is achieved at 19 bar. ELECTRIC STROKER By mounting an electrically modulated pressure control valve on the hydraulic stroker to establish the control pressure, pump stroke is controlled by an electrical signal. At 150 to 200 mA electrical signal, the pump commences to stroke, and at approximately 390 mA, the pump will be at full stroke.
