Product Introduction:
1、 Product Overview
The precision small electric explosion-proof fluorine lined regulating valve is composed of a low flow resistance straight through single seat valve or a low flow resistance sleeve valve matched with German imported PSL series and Japanese tooling 3610 series straight stroke electric actuator. The electric actuator has a servo amplifier inside, which does not require a separate servo amplifier. It can be controlled by an input control signal (4-20mADC or 1-5VDC) and a single-phase power supply to adjust parameters such as pressure, flow rate, temperature, and liquid level. It has the characteristics of small size, light weight, simple connection, high flow rate, and high adjustment accuracy, and is widely used in industrial process automatic control systems in industries such as power, petroleum, chemical, metallurgy, environmental protection, light industry, teaching and research equipment.
