Electric single seat control valve overview:
ZDSP electric single seat control valve is suitable for the pressure difference is small, the medium viscosity is larger or slightly particulate impurities on the occasion, by the PS series and 3810 series straight stroke electric actuator and low flow resistance through single seat valve composition. Electric actuator for electronic integrated structure, a servo amplifier, the input control signal (4-20mADC or 1-5VDC) and the power to control the valve, it can regulate the parameters of pressure, flow, liquid level, temperature etc.. Electric single seat control valve has the characteristics of sensitive action, simple connection, large flow, small volume, high adjustment precision and so on. The control precision and performance are obviously higher than that of DKZ type. The electric single seat control valve is suitable for the situation that the leakage quantity is strict, the pressure difference between the front and the back of the valve is low and the viscosity is certain, and the utility model is widely used in electric power, metallurgy, chemical industry, petroleum, environmental protection, light industry, equipment and other industries.
