Date:2021/2/24 14:51:46 Visits: Author:Dongfang YOYIK Engineering Co; Ltd,


Shut off valve HGPCV-02-B30 is a kind of pressure control valve. It has been widely used in EH oil system of DEC steam turbine unit. HGPCV-02-B30 is installed on each continuous control actuator for on-off control of EH oil.

Before leaving the factory, the shut-off valve needs pressure calibration, mainly for the setting of action pressure value. Generally, the action value of 300MW unit is set to 4.5MPa, which means that when the oil pressure reaches 4.5MPa, the oil can reach the servo valve through the shut-off valve. When the turbine is switched off, it will automatically block the passage of oil to the servo.
