Thrust washer
The thrust washer locks the disc plate in the butterfly valve body.
Thrust rod
The thrust rod is made of polyphenylsulfone (PPSU) reinforced
by a stainless steel insert.
Disc plate
The disc plate is made of a composite material (PPSU) using the press forming technology. The material used in conjunction with the manufacturing technique makes it possible to obtain a smooth sealing surface, thus preventing wear and tear, reducing friction, and extending the valve service life.
Press-on bush
Press-on bush is made of stainless steel and is corrosion resistant to the aggressive media.

Press-on bush is made of stainless steel and is corrosion resistant to the aggressive media.
Ball seal valve
Valve seat guide
The valve seat guide is made of fluorine rubber ИРП-287 НТА or from polytetrafluoroethylene (PTFE).
Thrust rod, lower
The thrust rod is made of polyphenylsulfone (PPSU) reinforced by a stainless steel insert.
Body material – The body material is a composite press material (кГМП) notable for its high strength and resistance to high temperatures and exposure to the aggressive media. The composite press material possesses a considerable corrosion resistance and as to its reliability is equitable to metal.
Application under the conditions of the high-rate flow of
the corrosive media (water, aqueous vapour, acids, organic substances, abrasive particles, petroleum products).
FUNCTIONS AND CHARACTERISTICS:
Operation by hand and from the electric drive.
The butterfly valves are in compliance with the requirements of GOST Standard 13547, GOST Standard 122063, GOST Standard 9544.
QUALITY:
Oil producing industry, petroleum refining industry, gas industry, chemical industry, water supply, heat supply and sewerage networks.
FIELD OF APPLICATION:
MATERIALS:
Use is made of the process-wetted high-strength composite thermoset polymer КПМП (ТУ 2253-189-07506004-2014), as well as of: Polytetrafluoroethylene (PTFE); Rubber mix ИРП 1287 НТА (ТУ 38-005-1166-98).

CHARACTERISTICS
PROTOTYPE TESTING OF THE EQUIPMENT
SETS OF COUNTERFLANGES
The counterflange is a necessary part for laying and repair of pipelines. The counterflanges are basically a reducing piece for connection of the pipeline elements to each other, and used for the pipeline hook-up to the equipment. There are some variants of the articles, the most in-demand of which are the counterflanges, which comprise the nonreturn part of the flange connection.
ELECTRIC DRIVES
The ball valves and butterfly valves manufactured at our enterprise can be completed with the electric drives made by various producers, which ensures remote control of opening/closing and integration into the Customer’s pipeline Computer-Assisted Management System.

The counterflange design.
Used in the process of the pipeline accessories assembling, are the sets of the counterflanges consisting of:
- gaskets;
- fastening device;
- the counterflanges per se, with the mounting interface surface;
- documents and instructions.

Production standards
In Russia and elsewhere in the CIS countries, there are three most abundantly used types of the counterflanges:
- steel plate welded flange is manufactured in compliance with the requirements of GOST Standard 12820-90;
- welded neck flange (steel, weld neck raised flange) in compliance with the requirements of GOST Standard 12822-80;
- loose ring joint flange proceduralised by GOST Standard 12822-80.

Steel plate welded flanges are used in the pipelines with the pressure not exceeding 2.5 MPa.
Welded neck flanges are suitable for the pipelines with the pressure level of up to 20 MPa. Ring joint flanges are used in the pipeline transportation systems with the pressure up to 2.5 MPa located in the hard-to-reach places, as well in case of necessity of frequent pipelining.

Usage of the counterflanges
Every separate variant of the counterflanges has its own range of application. Plain flanges are used in the systems with the low working pressure, first and utmost, in the long-distance pipelines, which transport the low-pressure media. The flange assembly is not difficult, and their design is reliable. On the whole, the counterflanges are used in all sectors of economy connected with the pipeline construction.

Counterflanges material 
As a rule, the counterflanges are manufactured from steel fittings. Basically, they are stainless steel, carbon galvanized steel or steelwith the thermodiffusion coating. The counterflanges can be operated at different temperatures from 70 to 300 degrees, which makes them the universal completing parts necessary for the pipelining.

Complete with manufactured at our enterprise shut-off valves, we also effect a sale of the companion flanges produced by our partner, the limited liability company “Parts of special-purpose” (LLC “DSN”). Cost of every specific order is calculated on an individual basis based on the request. It depends upon the specific type of the article, material, quantity, and order schedules.
