FUNCTIONAL DESCRIPTION OF REGULATOR Control Type Hydraulic Symbol Control Curve A - Pressure compensator control 1 - When system pressure increase and reach preset pressure the flow decrease automatically and pressure maintain without changing. 2 - Flow and pressure can be adjusted manually. B - Multi-stage flow & single-stage pressure control (with cylinder) 1 - Flow can be adjusted form zero to maimum and pressure can have been maintaining at preset pressure. 2 - Absorbing impact and vibration which are produced by up and down motions of actuators. It is suitable for lifting equipment etc... C - Two-stage pressure & flow control 1 - Low consumption electric motor can be selected to save energy because of the functions of high flow at low pressure and low flow at high pressure. 2 - When pressure increase and reach preset pressure "PH", flow is reduced to "QL". 3 - Pressure "PH-PL"and Flow "QH QL" can be adjusted optionally. 4 - It is applied to actuators requiring long unloaded or short loaded strokes. Speedy and horse-power efficient. CG - Two-stage remote pressure & flow control 1 - The same function of "C" control type. 2 - The pressure range can be adjusted remotely by the integrated remote pressure control valve. 3 - Proportional Electro-Hydraulic pressure control can be applied with proportional valve.
