23D-63B steam turbine turning solenoid valve
Turning solenoid valve 23D-63B is designed for turbine steering control. Turning gear is a driving device that drives the shaft system to rotate before and after the steam turbine generator unit is started and stopped. The turning gear is installed on the rear bearing box cover between the turbine and the generator. When it is necessary to rotate, first pull out the safety pin, push the handle and hand turn the motor coupling until the meshing gear is fully meshed with the rotating gear. When the handle is pushed to the working position, the contact of the travel switch is closed and the steering power supply is connected. After the motor is started at full speed, it drives the turbine rotor to rotate. -
AST/OPC solenoid valve coil 300AA00086A
The AST/OPC solenoid valve coil 300AA00086A can be equipped with an emergency trip solenoid valve, which is an emergency stop device, also known as a safety valve or emergency shut-off valve. Its main function is to quickly cut off the power supply or medium flow in case of danger or emergency, in order to protect the safety of equipment and personnel. Emergency trip solenoid valves are generally controlled by electrical or pneumatic signals, which have the characteristics of fast response speed and high reliability. In power plants, emergency trip solenoid valves are important safety protection devices that require regular inspection and maintenance to ensure their normal operation and reliability. -
AST solenoid valve coil Z6206052
The solenoid valve coil Z6206052 is a plug-in type and is used in conjunction with the valve core. Thread connected oil manifold blocks play a corresponding role. Used for emergency trip systems of steam turbines, where the trip parameters of the turbine control the closure of the inlet valve or speed control valve. -
AST/OPC solenoid valve SV4-10V-C-0-00
The AST/OPC solenoid valve SV4-10V-C-0-00 is a valve that is opened or closed by electromagnetic force. Used in gas or liquid circuits. There are many types of structures, but the principle of action is basically the same. When the control circuit inputs an electrical signal, a magnetic signal is generated in the solenoid valve. This magnetic signal drives the electromagnet to generate an action, corresponding to the opening and closing of the valve. -
SHV4 EH oil system needle globe valve
SHV4 EH oil system needle globe valve can accurately adjust and cut off the fluid, and plays the role of opening or cutting off the pipeline in the oil supply system of the power plant. Closing the stop valve can block the oil circuit of the system, and some hydraulic spare parts in the equipment can be repaired or replaced online. It’s suitable for high pressure and high temperature pipelines in thermal power plants as an opening and closing mechanism, can control the full opening and full closing of the oil circuit, and can also throttle by adjusting the opening of the poppet valve.
SHV4 EH oil system needle globe valve is small and light, which is used to open or cut off pipeline passage in fire resistant oil system of power plant. -
Needle Type Globe Valve SHV6.4
Needle Type Globe Valve SHV6.4 is mainly applicable to EH oil control systems. The high-pressure oil supplied to the actuator flows through the stop valve to the servo valve to operate the hydraulic servomotor. The needle valve can control the full opening and full closing of the oil circuit, and can also throttle by adjusting the opening of the cone valve. It is mainly composed of a valve rod, a body, a cushion block, a retaining ring, an O-ring, a cone core, and a cover nut.
