Valves and downhole accessories

The valves and the well casing is widely used in equipment for underground mining, drilling equipment skazhin, packer, Equipment for oil and gas. The company develops and manufactures valves, including valves are shut off and the well snap since 2002, using modern production facilities, technologies and materials. The products manufactured by the company complies with the requirements for operation and security and is certified by API and ISO.


Designed for pressure equalization between the annulus and the tubing.

Provides communication between the tubing and the annulus.

Serves to open and close circulating valve.

Serves to open and close circulating valve.

Provides communication between the annulus and the tubing during well testing and completion.

Allows for individually regulated volumes of fluid be injected into two isolated zones through a single tubing string.

Provides communication between the annulus and the tubing.

Provides fluid (gas) circulation between the annulus and the tubing during well interventions.

Provides isolation of concentric tubing strings during dual completion.

Provides withdrawal of gas in wells with high annulus pressure and reduces backpressure.

Enables pressure testing of the tubing or drilling string.

Provides temporary isolation of the tubing string to allow circulation or chemical injection below.

Designed for injection of chemicals in the tubing string or in the annulus.

Helps to set a packer (or a multiple packer assembly) when tubing weight can't be conveyed to the packer or setdown weight is not sufficient (at low depths).

Isolates the formation from brine or other weighted completion fluids during remedial work on ESPs.

Enables disconnection of the tubing string from the packer.

Provides means of retrieving the production string without unsetting the companion packer below as well as sealed reconnection to the packer.

Enables automatic disconnection (reconnection) of the tubing string from (to) the packer.

Used to remove debris from the bottom of the well (sand, scale, solid particles).

Used to remove debris from the bottom of the well (sand, scale, solid particles).

Serves to house retrievable chemical injection mandrels, dummy valves and other downhole tools.

Designed to effectively remove metal objects, hard-alloy teeth of roller-cone bits and other ferrous debris from the bottom of oil and gas wells.

Designed for safe release of the tubing from the downhole tools below should they become stuck.

Designed to remove debris from the mud and protect the drilling string as well as to prevent any foreign material from entering the drilling string during replacement of drill pipes and tools.

Designed to protect critical downhole equipment from debris (sand, scale, solid particles) and to catch foreign materials (lost cable bands, etc.) during subsurface pump replacement.

Provides unrestricted re-entry of subsurface or wireline (logging) tools into the tubing string.
