servo valve PSSV-890-DF0056A use for steam turbine DEH system
Date:2024/4/30 11:13:15 Visits: Author:Dongfang YOYIK Engineering Co; Ltd,servo valve PSSV-890-DF0056A is an electromechanical converter that can conduct forward and reverse currents. The pilot part can be a nozzle baffle valve, nozzle valve, deflection injection element valve, and slide valve. The pressure is always maintained at both ends of the power valve. Output four ports: P, A, B, and T. Be sure to install a precision oil filter at the inlet of the servo valve. Servo valves are usually installed near or above the servo cylinder. Servo valves have high working frequency, high sensitivity, and good control accuracy. The valve receives output instructions from the servo amplifier, controls the movement of the internal slide valve, changes the size of the oil port, and controls the unit to adjust the valve opening, timely and quickly adjust the unit load, and meet the needs of external users for electricity load changes. Therefore, under normal working conditions, if the servo valve operates frequently, it is even more important to do a good job in regular protection work.
