1、 Product Overview
Electric regulating ball valveIt is composed of HQ type intelligent electric actuator and two-way ball valve body, suitable for two position cutting and adjustment occasions. The actuator can be domestic or imported, and adopts an integrated structure,electric actuatorBuilt in servo system, input control signal (4-20mADC or 1-5VDC) and single-phase power supply can control the operation. The intelligent electric ball valve has strong functions, small size, lightweight and pleasant, reliable performance, simple matching, large flow capacity, and is particularly suitable for occasions where the medium is viscous, contains particles, or fibers. currentlyElectric regulating ball valveWidely used in industrial automatic control systems in industries such as food, environmental protection, light industry, petroleum, papermaking, chemical engineering, teaching and research equipment, and power.
