Gate valves are made of steel and cast iron grades 20Л СЧ 25, ВЧ 40, with flange, PE (polyethylene) nozzles, welding, hand-operated (with flywheel) or performance under actuator.
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;
- Steel or 10Х17Н13M2T 12Х18Н12M3TЛ.
The required performance of selected operating conditions, aggressive working medium temperature.
Missing data in the catalog are available upon request of the consumer.
OKП code 3741 Production and delivery TУ 3741-001-68142220-2010
They are made with flanged, socket joining, welding to the pipeline. Mounting flange dimensions according to GOST 12815-80, version 1, row 2 (the default).
In the valves used a solid wedge.
Tightness of the gate according to GOST 9544-2005 Class A and B.
Gland packing - stuffing. In the upper position of the spindle has a seal on the conical surface of the lid.
Management manual valve (handwheel).
When ordering, specify: product name, the parameters of the working environment, nominal size (orifice) (DN), nominal (conventional) pressure (PN), product designation, the performance of the material, the need for additional testing.
Example for ordering (and other documentation) gate valve DN 15 mm PN 40 kg/cm2 steel 09Г2С:
Wedge gate valve ЗКЛ 15-40-01 DN 15 mm PN 40 kg/cm2 30лс15нж.
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.
