Oil source pressure 0.8MPa (0.6~1.2MPa)
Filtration accuracy ≤40μm
Liquid temperature 10~70°C
Secondary oil pressure working range 0.15~0.45MPa
The servo amplifying device, also known as the oil motive, is an actuator for regulating the steam valve, which converts the secondary oil outputted by the amplifier or the electro-hydraulic converter into a stroke having sufficient functional force to operate the regulating steam valve to control the steam inlet of the turbine.
The servo amplifying device has a structure of a double-acting reciprocating flow.
