ZRQM-2 Intelligent Electric Control Valve
I. Product Overview:
The ZRQM-2 intelligent electric control valve consists of a 3810L (or PSL series) linear motion electric actuator and a compact single-seat valve. It includes a servo function, accepts standard signals of 4-20mA or 1-5V·DC, converts the current signal into a corresponding linear displacement, and automatically controls the opening of the control valve to continuously adjust process parameters such as pressure, flow rate, temperature, and liquid level of the fluid in the pipeline. It is suitable for occasions with strict leakage requirements, low pressure difference before and after the valve, certain viscosity, and a small amount of fiber-containing media. It is a pressure-balanced control valve. Equipped with the RQM series intelligent electric actuator, the overall structure is compact, light in weight, and has good stability and high protection level, so it is widely used in automatic control systems such as large thermal power plants, chemical plants, water treatment and sewage treatment, natural gas oil fields, and steel plants.
