T968Y electric high differential pressure regulating valve

關注次數：

T968Y electric high differential pressure regulating valve is composed of PS series or 3610 series of straight travel electric actuator and low flow resistance through single seat valve. (also can be equipped with other brands of linear actuators). Electric actuator for the electronic integrated structure, a servo amplifier, the input control signal (4-20mADC or 1-5VDC) and the power to control the valve opening, to adjust to working parameters of pressure, flow, liquid level, temperature etc.. Is sensitive, simple connection, big flow, small volume, high accuracy regulation. The control precision and has better performance than DKZ.
Single seat valve is applicable to strict, valve and pressure is low and has certain viscosity occasions of leakage for. Widely used in electric power, metallurgy, chemical industry, petroleum, environmental protection, light industry, equipment industry.
