Stop valves on gas pipelines serve to control gas flows. It is able to regulate the flow in pipeline systems from a minimal reduction in supply to its complete stop.

We offer the following types of this equipment from the best global manufacturers:
⦁ cast iron shutters;
⦁ regulating valves;
⦁ faucets;
⦁ disc shutters.

All locking devices have a similar design. This is a closed hermetic case in which the shut-off valve assembly is placed.

The housing most often has two (in some cases more) ends, with the help of which it is tightly attached to the pipeline. The purpose of the shut-off unit is to hermetically divide the pipeline system into parts.

It consists of a seat and a locking device, which are constantly in contact with the sealing surfaces.

The tap is connected to the pipeline using a flange, a coupling or by welding to it. Gas coupling valves are used on gas pipelines.
Cap coupling cranes can withstand higher loads. They service oil pipelines and water pipelines, their main parts are made of cast iron. At the same time, the cast-iron stuffing box is stuffed with rubber or hemp. Such faucets are able to work at pressures up to 1 MPa and withstand temperatures up to 100 ° C.

Ball valves have the smallest dimensions. This equipment is famous for its high quality work, which led to its use in pipelines of large diameter. They are made of cast iron, and the sealing rings are made of fluoroplastic-4.

Control can be both remote and with the help of a flywheel.

Cranes with a ball valve and a hydropneumatic drive of the “Cameron” company are designed and used as a shut-off device on main gas pipelines, compressor and gas distribution stations, and underground gas storage facilities.
