The set is intended for sealing the wellhead of oil wells, regulating their operation mode, installing and connecting devices for examining wells and carrying out technological operations.

The wellhead kit is equipped with reliable, easy-to-operate and high-tight ZD 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.

The kit is intended for use in wells with a high paraffin content.

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.
