liquid and gaseous and aggressive media.
Flanged ball valve 900D series – “Duplex”, DN 15-100, PN 1.6 – 4.0 MPa, two-part design, flanged
The connection to the pipeline is flanged, at the request of the customer, they can be completed with matching flanges, gaskets and fasteners.
Features: die-welded, collapsible, single-pipe construction, low metal consumption, lower price category, the possibility of using instead of valves due to the shortened construction length. Double dimensional row of construction lengths according to GOST 28908-91 row 3 and row 1.
Recommended by the manufacturer for thermal power plants, utilities, chemical, oil refining and other industries.

The Duplex ball valve consists of a housing 1 and a branch pipe 2, tightened together by studs 13 and nuts 14. In this case, the fluoroplastic seals 5 are pressed against the floating plug 3, and the ring 6 seals the joint of the housing with the nozzle. The counter-flying spindle 4 is sealed with a package of fluoroplastic rings 7 and 8, compressed by disc springs 11 through the sleeve 10 and tightened by a nut 12. A fluoro rubber circular ring is also installed in the groove of the spindle 4. Supply of the working medium – to any of the pipes. The crane is switched manually by turning the handle 15 by 90°. Stopping in the extreme positions is provided by a stop 16 fixed on the body and the spout of the handle 15. The spatial position of the crane on the pipeline is arbitrary.

The Duplex flanged ball valve is installed on pipelines through which aggressive liquid and gaseous media are transported under pressure from 1.6 to 4 MPa with a heating temperature of up to 160 ° C. They are recommended for use in thermal power, chemical, oil refining and other industrial enterprises.
Important technical and operational features of this shut-off valve include:
The cranes of the Duplex series are produced in three versions of the housing:
Manual control via a rotary knob without the possibility of fixing the angle of rotation in an intermediate position.
The housing design and the sealing material are selected depending on the future operating conditions and the aggressiveness of the transported medium.
