Quality is everything! US Walker (WORK) imported by electric single seat control valve actuator and straight trip through single seat valve two-part, single-phase 220V power supply for the power to accept 0 ~ 10mA or 4 ~ 20mA DC signal, automatically controlled adjustment valve opening, to the fluid pressure within the pipe, flow, level and other process parameters adjusted continuously. The product has a sensitive, convenient access to energy, rapid signal transmission characteristics. Widely used in electric power, metallurgy, chemical, textile and other industrial automation control systems. Imported electric single seat control valve structural characteristics: 1. features strong, reliable, simple connection, high precision adjustment to changes in the output thrust straight trip valve opening displacement reaches of the fluid medium craft 2. electronic electric single seat , seat control valve automation control system is the instrument of execution units to AC220V power supply voltage for power, operating and other inputs (4-20mA, 0-10mA or 1-5VDC) current or voltage signals, to control operation 3. The use of mechatronic structure, with the machine operation and the opening of the servo position feedback signal, position indicator, manual operation and other functions.
