The inter-flange ball valve consists of a housing 1, into which a plug 2 is installed, sealed with seats 5. The seats are crimped along the plug when wrapped in the housing of the sleeve 3, ensuring the tightness of the gate. The threaded connection of the sleeve 3 to the housing 1 is sealed with a fluoroplastic ring 9. Opening and closing is carried out by turning the handle 11 mounted on the spindle 4. The spindle is installed in the boss of the housing and is sealed with a package of fluoroplastic (pos. 6, 7) and rubber rings 13. The package is fixed with a sleeve 10 and a pin 12. The position on the pipeline is arbitrary.

Today, flanged ball valves have won the market for installation in large-sized pipelines. Although two decades ago, the only option in this segment were valve cranes. But their huge dimensions and the inconvenience of operation have sharply raised the need to find a new solution. The flanged cranes do not have any connecting elements in the design, they are mounted directly between the flanges previously welded to the system, and then they are tightened with studs.
Accessories of this type are made with a steel body and provide the following advantages:
The main scope of application of flanged ball valves is the chemical, oil refining, pharmaceutical and food industries.
The price of an inter-flange ball valve varies depending on many factors, including pressure, diameter and material design. Additionally, the individual wishes of the customer are taken into account.
You can buy a ball valve at an affordable price in JSC “RC “Fobos” by making an application by phone 8 (800) 700-62-60 (Moscow and all Russia) or using the services of regional managers, as well as by e-mail 14@fobosarm.ru
Delivery of ball valves is carried out by the services of transport companies – Business Lines, PEC. Also, transportation is carried out by rail Zheldorexpedition and other types of delivery with payment for transport services and cargo insurance services by the buyer.
