A small fine electric single seat control valve (sleeve), low flow resistance through single seat valve, sleeve valve or low flow resistance with German import PS or 3810 series actuators. The electric actuator has no additional servo amplifier, servo amplifier, the input control signal (4 20mADC or 1 5VDC) and single-phase power can control the operation, we can adjust the parameters of pressure, flow, temperature, liquid level etc.. The valve has the advantages of small volume, light weight, simple connection, large flow, high accuracy regulation, widely used in electric power, petroleum, chemical industry, metallurgy, environmental protection, light industry, teaching and research equipment industry automatic control system.
