Pilot solenoid valve as a control valve guide valve

Used to control the the piston actuator control valve opening and closing or to secure his position, but also as the air passage switching of the control system. Typically, the pilot solenoid valve fluid is compressed air, hydraulic oil in hydraulic systems, application of the pilot solenoid valve is required with other devices, such as spool valve to achieve the desired flow path switching with. The direct-type solenoid valve for the direct control of the fluid off.
Solenoid valve has a remote control, fast response, tightly closed the fluid leakage characteristics of the accused. It should be noted that the solenoid valve working parts directly in contact with the charged fluid, so selection should be determined based on the performance of the fluid solenoid valve type. The solenoid valve is commonly used for position control or control requirements are lower, but requires strict sealing applications. For example, heating fuel gas feed, air and water media. Application in hazardous areas should be used in the appropriate explosion-proof solenoid valve.flange solenoid valve
Electric speed pump is usually electric speed pump AC variable speed AC motor speed control, flow control. FM AC motor speed control method of speed control, adjust the pole synchronous AC motor for governor and turned the slip speed control of three from the slip effect, only the FM governor, adjusting the number of pole pairs governor two governor.shut off solenoid valve
The speed control system using the open-loop control, or the composition of the speed feedback control voltage, current, or position signal can also be added to form a complex control system. The past twenty years, due to the vector control with fast dynamic response, stable operation, AC motor speed control system using the rotation vector control technology has been widely used.
