QSLP intelligent electronic electric single-seat regulating valve
Other Products
I. Introduction:
The QSLP intelligent electronic electric single-seat control valve is equipped with on-site electric manual operation function, which can be operated via the up key or down key. It has a digital display window that shows the control signal value, feedback signal value, and electric manual operation value. It is equipped with fault judgment, alarm and protection functions for broken control signals. When the signal is broken, the actuator can be opened, closed, kept in its current state, or set to any value between 0~100%. It also has fault judgment, alarm and protection functions for valve stall. Hardware-wise, it adopts upper and lower limit switches, enabling the actuator to have dual protection functions. With an integrated structural design, the valve position feedback component and servo amplifier are installed as two independent parts inside the actuator. It directly accepts control signals such as 20mA/4~12mA/12~20mA/0~5V/1~5V, outputs isolated 4~20mA valve position feedback signals, and has self-diagnosis functions, making it very convenient for use and calibration. It features a simple structure, compact size, and light weight, facilitating installation and maintenance. The transmission system entirely uses low-backlash sealed gears, with characteristics of high efficiency, low noise, long service life, stability and reliability, and no need for additional lubrication.
