Iran's Parsian Gas Refining Company "Breaks US Monopoly" on Control Valves

June 10, 2014

Parsian Gas Refining Company has broken the US and Canada monopoly on the manufacturing of control valves, the company’s chief said.

Farshid Ebdali said the domestic manufacturing of control valves has saved the country 60 billion rials. He said that control valves are strategic elements in gas refineries, adding that two sizes of these valves have been manufactured in Iran.

Ebdali said each valve facilitates the flow of 25 to 28 mcm/d of gas.

Control valves are valves used to control conditions such as flow, pressure, temperature, and liquid level by fully or partially opening or closing in response to signals received from controllers.

The most common and versatile types of control valves are sliding-stem globe and angle valves. Their popularity derives from rugged construction and the many options available that make them suitable for a variety of process applications, including severe service.
