In modern process industries—from chemical plants to oil and gas facilities—control valves play a crucial role as the “final control element” in regulating the flow, pressure, temperature, and level of fluids. Their selection, operation, and integration into process control systems can dramatically affect efficiency, safety, and product quality.

Determine what the valve is supposed to do.Is this valve used for tight control or is”loose”control acceptable. (For instance, are you trying to control a flow within a very tight margin across a broad range of process conditions or are you simply throttling a charge flow down as it approaches setpoint to avoid overshoot). The requirements for one situation are quite different from the other.

Control valve selection can be challenging even for experienced technicians. You should be familiar with regulation technologies and the types of control valves available.In the next section, I will describe what a control valve is and the different types of valves available.Read on to learn more about the technology behind control valves, their types and applications in industry.

With the rapid advancement of the modern chemical industry, the need for valves that can withstand highly corrosive media under special operating conditions has become increasingly critical. Traditional materials like stainless steel and rubber-lined valves often fall short in such environments. While alloys like Hastelloy, Monel, and Alloy No. 20 offer superior corrosion resistance, their high content of rare metals such as Ni, Cr, Ti, Mo, Nb, and Pt makes them expensive and resource-limited.

Fluorine-lined control valves are revolutionizing the agrochemical industry with their unmatched “corrosion resistance”, “sealing performance”, and “durability”. Designed to handle highly corrosive, toxic, and crystallization-prone media such as pesticides, fertilizers, and herbicides, these valves ensure safe, efficient, and reliable operations. Discover how fluorine-lined control valves can optimize your agrochemical production processes and reduce maintenance costs.
