TU 3665-009-4965 2808-2004

Арматура устьевая АФ6-100х21К1М4

The fittings are designed for sealing oil wellheads, regulating their operation mode, installing and connecting devices for examining wells and performing technological operations.

The valves are equipped with reliable, easy-to-operate and high-tight ZD gate valves.

The lack of free volume in valves of this type excludes the possibility of water ingress and freezing in the valve body. The alloys and materials used provide high wear and corrosion resistance.

Has no welded joints.

The climatic version of the wellhead fittings is UHL1 (HL1) in accordance with GOST 15150-69.

The limiting values ​​of the operating temperatures of the ambient air are from +40 to -60 ° С.

By agreement with the customer, any design and configuration options are possible.
