QWSD Miniature electric ball valveDetailed product description：

The QWSD miniature electric ball valve is a type of ultra small electric valve. Its integrated design of actuator and valve body greatly reduces the external volume, providing convenience for use in instruments and small equipment. The valve ball and stem adopt a floating sealing structure, which reduces torque and overcomes the problem of ineffective switching caused by scaling. It has been widely used in HVAC, central air conditioning systems (fan coil units), solar energy (engineering and civil water heaters), water-saving appliances (university card water-saving systems), environmental engineering, water supply and drainage, water treatment, prepaid cold and hot water meters, industrial automation and other industries.
