Features large flow-through body fluids clean ideal special process to avoid leakage of the scope of application performance and stability of electric agencies electric valve with integrated structure, with DTR electric actuators to match, there is an input control signal (4 ~ 20mADC or 1-5VDC) and Single-phase power to control the operation, with strong function, small size, light and pleasant, reliable performance, supporting simple, flow capacity, especially suitable for viscous media containing particles, fibers nature of the occasion. At present, the valve is widely used in food, environmental protection, light industry, petroleum, paper, chemicals, teaching and research equipment, electric power industry, industrial automatic control system.
