Overview
Electric single-seat control valve is driven by single-phase
220V power, receives 0～10mA DC signal, automatically controls
the opening of valve, to continuously adjust pressure, temperature,
flow, liquid level and other process parameters. Widely used in
power, metallurgy, petroleum, chemical, light industry, food
department and other automatic control systems
