for installation as a Russian-made shut-off device on pipelines transporting liquid and gaseous media (methane) at cryogenic temperatures.
Cryogenic welding-end ball valves are intended to be fitted as stop/shutoff valves on pipelines of liquid and gaseous media (methane) at cryogenic temperatures. Distinctive features of these valves are possibility to use at low temperatures till -196 °С and casting design of valves.

The ball valve consists of the body (1) and the caps (2) bolted together by bolts (12). The ball seat (7) presses the ball (3). The joining of the valve body and the caps (2) is sealed with the joint gaskets (8). The stem (6) has an extension center. The valve is supplied with a pipe (4) bolted to the body (1), the stem (6) is inside this pipe. There is a sealing set in the upper part of the pipe consisting of thrust washers (10) and a bonnet (5) bolted together by nuts (16) stud bolts (15). Для уплотнения соединения фланцев 14 и 15 между ними расположена прокладка 18. The movement assembly has a handle (14) and a stop (13) fixed in the end part of the stem (6). Such design provides for using the valve if in the pipeline there is a pipe covering witch increases significantly the diameter of the pipeline because of the handle placing outside this pipe covering.

Cryogenic welded ball valves are used as shut-off devices on pipelines transporting highly cooled liquid and gaseous media. An important design feature of the armature is the presence of a solid cast housing and a high spindle installed inside the prefabricated column. Such a crane device allows you to provide an effective thermal insulation device.
Transported media: liquefied natural gas, propane, liquid nitrogen, freon, refrigerants and other cooled and liquefied substances.
The main assembly elements of the cryogenic crane are:
The pipes are bolted, with the installation of sealing rings. The column is fixed on a flange included in the overall configuration of the structure. The presence of a high spindle allows you to install a cryogenic crane with a thick layer of thermal insulation on the pipeline.
Main operational parameters:
The estimated service life without repair is 10 years.
The price of a cryogenic welded 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 email@example.com
Delivery of welded cryogenic cranes 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.
