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. As a regulating body (AFK1SH), a disc choke valve ZDSH is used, which is designed for stepwise regulation of the liquid flow rate. Replacement of fittings in the ZDSH gate valve is carried out by one operator within 3-5 minutes with the gate closed position without relieving pressure from the system.
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.
Can be transformed into ANC variant.
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.
