III Electric single-seat control valve is driven by
single-phase 220V power, receives 0～10mA
DC or 4-20mA 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
