The company was established in November, 5, 2005.

The company has attracted experienced specialists in the field of development and production of oil and gas equipment, namely: designers, technologists, scientists, and the best representatives of the working professions: turners, millers, welders, assembly fitters, etc.

Our specialists have developed classic and full-bore valves, for example, a safety valve, top drive valves and so on. Classic kelly valve can be made with tubing thread and thread for drill pipe based on the wishes of the customer.

Thanks to own production, our experts can experiment with properties of metal which increase durability and reliability of a product. One way to increase the durability is nitriding, which increases the life of parts like the ball, saddles and other things.

Kelly valves and dart valves resistant to sulfide stress cracking. The entire technological process of heat treatment and selection of the appropriate material has been developed by our specialists. These products are highly demanded by drilling companies.

KELLY VALVES ONE PIECE

Designed for automatic overlap and pressurization of the drilling instrument tube channel in drilling oil and gas wells, and also in maintenance and emergency works.

The valve structure allows maintaining pressure in any direction. The valve may be installed above and under the work tube. The platelike spring ring provides reliable sealing. The valve is designed for a standard operating pressure of 10000 Psi, but upon customer's request the structures may be produced designed for higher pressure.

Kelly valves can be produced for drill string or pump-compressor pipes.

KELLY VALVES TWO PIECE

Designed for automatic overlap and pressurization of the drilling instrument tube channel in drilling oil and gas wells, and also in maintenance and emergency works.

The valve structure allows maintaining pressure in any direction. The valve may be installed above and under the work tube. The platelike spring ring provides reliable sealing. The valve is designed for a standard operating pressure of 10000 Psi, but upon customer's request the structures may be produced designed for higher pressure.

FULL-BORE VALVES

Designed for tubing channel overlap under conditions of moderate and cold macroclimatic areas.

Channel overlap is performed in potential gas and oil showing and work stoppage in well repair as part of tubing in various process procedures.

The valve is designed for a standard operating pressure of 10000 Psi, but upon customer's request the structures may be produced designed for higher pressure.

TOP DRIVE UPPER VALVES

Designed for using as part of the upper power drive system for prompt overlap and pressurization of the drilling instrument tube channel in drilling the oil and gas wells, and also in maintenance and emergency works.

The valve is designed for a standard operating pressure of 5000 Psi, but upon customer's request the structures may be produced designed for higher pressure.

TOP DRIVE LOWER VALVES

Designed for using as part of the upper power drive system for prompt overlap and pressurization of the drilling instrument tube channel in drilling the oil and gas wells, and also in maintenance and emergency works.

The valve is designed for a standard operating pressure of 5000 Psi, but upon customer's request the structures may be produced designed for higher pressure.

SAFETY VALVES

Designed for overlapping-opening the inner channel of pumping and compression pipes, has full passage equal to the passage of the channel of the relevant pumping and compression pipe.

The valve is designed for a standard operating pressure of 5000 Psi, but upon customer's request the structures may be produced designed for higher pressure.

DART VALVES

Designed for automatic overlap and pressurization of the drilling instrument tube channel in drilling oil and gas wells, and also in maintenance and emergency works.

Valve structure allows carrying out maintenance works under field conditions. The valves are produced with the right and left directed coupling thread coils.

The valve is designed for a standard operating pressure of 5000 Psi, but upon customer's request the structures may be produced designed for higher pressure.
