Fully welded Ball valve with butt-weld ends
Scope:
◆Systems of drinking and technical water supply.
◆The heating system and heating.
◆System natural, liquefied gas and petroleum products.
Design features:
◆Thanks to welded construction cranes AFC have less compared to the taps other versions weight. Ease of installation and, if necessary, subsequent heat insulation.
◆No maintenance.
◆Ball and stem made of stainless steel.
◆Tightness class "A" secured by a special stem seal.
◆Reliability is not less than 7000 cycles, due to the new ball seal made of PTFE.
◆Installation of cranes is possible in any position. Lever ball valves AFC detachable and can be rotated by 180º.

The full bore welded ball valves, welded ball valves stainless steel ball valves with welded extension stem for underground installation custom!
Ball valves welded widely used in urban underground pipelines, pipelines for transportation of natural gas, stations-pressure regulation and other areas. In recent years, the company managed to constantly improve the product quality through continuous research and innovation.
Ball valves welded, thanks to the welded construction, have high internal and external tightness and less weight(especially for 300 and less), which makes the installation of all-welded ball valves more convenient. This not only reduces construction cost but also saves time.
Underground welded ball valves can be directly buried underground without building an operational to control the valves, since the control is performed on the ground using T-shaped arm. It is very convenient and eliminate danger in case of control from control room under the ground.
All-welded ball valve, underground installation can be done with different stem height according to the depth of laying of gas pipelines in accordance with the requirements of the customer. We also have different types of connections of Your choice.
Welded ball valves can be performed with an incomplete pass(standard) and full-passage(non-standard).
