ZAJD Electric Regulating Butterfly Valve
ZAJD Electric Regulating Butterfly Valve
Product Characteristics
1. Product Model: Type ZAJD
Our company’s ZAJD electric butterfly valve is available in two types: switch type and intelligent type. It is designed to be paired with a butterfly valve and DTR actuator, allowing for operation control through input control signals (4~20mADC or 1~5VDC) and single-phase power supply. This versatile valve offers strong functionality, compact size, reliable performance, simple installation, and high flow capacity. It is particularly suitable for applications involving viscous media containing particles and fibers. Currently, the electric regulating valve for medium flow is widely utilized in industrial automatic control systems across various sectors including food processing, environmental protection, light industry, petroleum refining, paper production, chemical manufacturing, educational research equipment, as well as power generation.
