QSLEX-TP/VY Compact (low flow) explosion-proof electronic electric control valveDetailed product description：

QSLEX-TP precision small explosion-proof electronic electric control valve is an electromechanical integrated product composed of intelligent controller, actuator, and small flow valve, with high reliability and easy and flexible use. This product has a sophisticated structure and advanced control circuit. It can accept 4-20mADC standard analog control signals and also provide 4-20mADC standard analog valve position signals.

This product is designed according to explosion-proof requirements and has been inspected and approved by the National Instrumentation Explosion proof Safety Supervision and Inspection Station (NEPSI). Its explosion-proof mark is ExdIICT4 (excluding acetylene) and the explosion-proof certificate number is GYB04304X. It can meet the requirements of explosion-proof places and the needs of various industrial sites, and can be widely used in small flow self-control systems in various industries such as ships, fine chemicals, power, metallurgy, petrochemicals, pharmaceuticals, etc.

Main features
Equipped with QSLEX explosion-proof plow electronic straight stroke electric actuator. Small size, light weight, easy operation, no adjustable potentiometer, high reliability, low noise.  
The QSLEX explosion-proof electronic linear electric actuator adopts an integrated structural design, which is very convenient to use and calibrate.  
QSLEX explosion-proof electronic linear electric actuator function: fault diagnosis and protection function with broken control signal. When the signal is interrupted, the actuator can be turned on or off; Or close; Or maintain; Or any predetermined position between 0 and 100%. And with valve blockage fault diagnosis and protection function.  
The valve adopts a top guide and single seat sealing structure. Compared with other similar regulating valves, it has outstanding advantages such as simple structure, large rated flow coefficient, and small valve seat leakage. In addition, with a soft seal structure, it has both regulating and cutting functions, making it a type of regulating valve that can be adjusted and cut off.
