Iranian Knowledge-Based Firm Produces Oil Control Valves for Car Industry
“Five million dollars in foreign exchange savings have been achieved with the production of the OCVs,” Dehqani Firouzabadi said.
The Continuous Variable Valve Timing (CVVT) performance control valve known as OCV (Oil Control Valve) is one of the products of the Iranian knowledge-based company, which plays a key role in the correct operation of the CVVT system in cars.
The oil control valve consists of a solenoid that has a coil and controls the oil flow for camshaft changes.
The CVVT system also plays an important role in adjusting the opening and closing time of the smoke and air valves of the car engine.
Iran needs 700,000 OCVs annually on average, and Shaygan company is the only manufacturer of this part in the country.
At present, the knowledge-based company has managed to supply over 20% of the country's automobile industry's need by producing 150,000 OCVs.
In a relevant development in August, researchers at an Iranian knowledge-based company had also succeeded in producing 32 gate valves needed in oil industry.
“We are a manufacturer of all kinds of valves needed by the oil, gas and petrochemical industries. The latest achievement of our company has been production of as many as 32 units of 20-inch gate valves of class 2,500 which have been used in development plan of Isfahan Oil Refinery. The achievement is considered as one of the largest valve-production projects of the oil companies in Iran,” Massoud Jalali, a representative of the knowledge-based company, told ANA.
Noting that valves are produced by using the open mold forging method due to the type of their structure, he said, “Open mold forging is a hot forming process in which metal is formed by hammering and pressing between flat or simple molds.”
“Gate valves are installed at the outlet of the distillery tower and are used to cut off and connect the flow. Also, the operation of these devices takes place at a temperature of 400 degrees (Fahrenheit) and 250 (Bar) of pressure; therefore, we should use heat-resistant materials in its construction,” Jalali said.
He explained that stainless steel materials should be used in metallurgy, saying, “This material is one of the most basic elements of gate valves and makes the valves resistant to heat.”
