Product Details
AEA GOST 5762 Cast Steel Gate Valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid. The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar. The gate faces can form a wedge shape or they can be parallel. Typical gate valves should never be used for regulating flow, unless they are specifically designed for that purpose. On opening the gate valve, the flow path is enlarged in a highly nonlinear manner with respect to percent of opening.

I Gate valves
Gate valves are shut off devices, in which the channel is covered by the translational movement of the lock body in a direction perpendicular to the flow of the transported medium. Gate valves are used to block flow of gaseous or liquid media in the pipeline at various pressures and nominal (conventional) passes.Body parts are manufactured as a method of molding and stamping.
Low hydraulic resistance valves (the drag coefficient of less than 0.5) makes them particularly valuable when applied to pipelines, which are constantly moving through a medium with great speed.
Execution valves closing element - a solid wedge. They fall into the valve with a solid wedge and double disc.
Seal in the gate from both the action on the wedge medium pressure (pressure difference before and after the gate), and additional efforts wedge.
Gate valves are manufactured with a rising stem (threaded spindle and nuts are running out).
Connection to pipe flanges, clutch, welding. Optionally flange may be any according to GOST 12815-80. By default, run on the flange PN ? 16 - version 1, PN 25, 40 - version 2 (by special order PN 25 - Version 3), PN 63, 100, 160 - Version 7 to GOST 12815-80 series 2.
Construction in accordance with GOST 3706-83 length.
Tightness of the gate according to GOST 9544-2005.
Management of manual valves (handwheel).
Operating position of valves in a horizontal pipe or flywheel drive up (a deviation of 45 ? in either direction) on the vertical - any.
Direction of the medium in the valve - on either side of the main aisles.
Catches of steel grades can be made four versions:
- Steel 20 or 20Л;
- Steel 09Г2С or 20ГЛ;
- Steel or 12Х18Н10T 12Х18Н9TЛ;

Attention! Valve, designed for gaseous, explosive and toxic environments, additionally tested after hydro air. When ordering, please make a note: "gas".
Basic information and information given at the beginning of the section.
The choice of application design, material and hull wetted parts depends on the aggressiveness of the medium, temperature, pressure, and working conditions, as well as customer requirements.

II Steel wedge gate valves, flanged, rising stem
Gate valves are shut off devices, in which the channel is covered by the translational movement of the lock body in a direction perpendicular to the flow of the transported medium. Gate valves are used to block flow of gaseous or liquid media in the pipeline at various pressures and nominal (conventional) passes.Low hydraulic resistance valves (the drag coefficient of less than 0.5) makes them particularly valuable when applied to pipelines, which are constantly moving through a medium with great speed.
On execution of the valve body is usually made full bore, ie diameters of the holes in the valve passages are not narrow. In some instances, narrowed valve in which the diameters of the holes in the hull narrowed. This reduces the effort and torque control systems, as well as reduced dimensions and weight, but it increases the hydraulic resistance. Aligned with a narrowed valve passage marked in the catalog with the letter "У" after the designation of nominal (nominal diameter).
Execution valves closing element - wedge. They fall into the valve with a solid wedge and double disc.
Seal in the gate from both the action on the wedge medium pressure (pressure difference before and after the gate), and additional efforts wedge. Because of this wedge gate valves (especially the double-disk) have a significantly higher degree of integrity than the parallel (in which the seal in the working body is mainly due to the pressure drop in it). They should be used when operating conditions are close to the maximum limit.
Gate valves are manufactured with a rising stem (threaded spindle and nuts are running out).
Connection to the pipeline flange. Optionally flange may be any according to GOST 12815-80. By default, run on the flange PN ? 16 - version 1, PN 25, 40 - version 2 (by special order PN 25 - Version 3), PN 63, 100, 160 - Version 7 to GOST 12815-80 series 2.
Construction in accordance with GOST 3706-83 length.
Tightness of the gate according to GOST 9544-2005.
Office of valves can be manual (handwheel) or from the actuator in a normal or explosion-proof design.
Operating position of valves in a horizontal pipe or flywheel drive up (a deviation of 45 ? in either direction) on the vertical - any. When you install a pipeline to provide additional support for electric drive.
Direction of the medium in the valve - on either side of the main flange.
Catches of steel grades can be made four versions:
- Steel 20Л;
- Steel 20ГЛ;
- Steel 12Х18Н9TЛ
- Steel 12Х18Н12M3TЛ.
The required performance of selected operating conditions, aggressive working medium temperature.
III Gate valves with а rubber wedge
Gate valves are shut off devices, in which the channel is covered by the translational movement of the lock body in a direction perpendicular to the flow of the transported medium. Gate valves are used to block flow of gaseous or liquid media in pipelines at various pressures and nominal (conventional) passes.Low hydraulic resistance valves (the drag coefficient of less than 0.5) makes them particularly valuable for use in pipelines and gas pipelines, through which the constantly moving environment with great speed.
On execution of the valve body is made full bore, ie diameters of the holes in the valve passages are not narrow.
Execution valves closing element - rubberized wedge to create the absolute integrity.
Seal in the gate from both the action on the wedge medium pressure (pressure difference before and after the gate), additional efforts and wedge sealing rubber coating of the wedge. Because of this valve with rubber-wedge has a very high degree of integrity, but they should be used when workers are non-aggressive environment used to cover the rubber wedge and the ambient temperature does not exceed 120 ? C.
