The parallel slide gate valve relies on the hydraulic cylinder liquid pressure to make the piston rod move up and down, leading to the spring connected with the valve stem to drive the valve disc. This straight displacement perpendicular to the fluid realizes the opening and closing of the valve. The shutoff disc should be pressurized at the upper end of the oil cylinder, the piston and the stem move from the top down, and the opening disc is opposite. The parallel sliding gate valve is mainly used in the main steam cut-off and isolation of thermal power units, main feed pump isolation, high-pressure heater isolation, steam turbine drainage system or used to control the effective cut-off or opening of high temperature& pressure steam water system.
