Design features
Carbon steel or alloy steel cast valve body.
Full-opening valve.
Corrosion-resistant facing on body rings.
Plug on the valve cap.
Rolling bearings.
Stuffing box rings are made of thermal-expanded graphite.
Technological advantages
Chemical and temperature resistance.
Low hydraulic resistance coefficient.
Pipeline cleaning and diagnostics can be performed without removal of valves.
Improved reliability and longer service life.
Pressure safety.
Additional sealing of valve gate (pressure feed).
.
Easy operation of valves.
Reduced frictional wear of stem.
Time between repairs increases n-fold.

Ball valves DN50-1200 PN 1,6-16,0 MPa, TU3742-005-05749375-99
Design features
Full opening valve.
Spring-assisted double-seal seats (primary - metal-metal, secondary metal-polyurethane).
Non-rigid fixing of secondary soft seal.
Forced lubrication of stem and seat seals.
Cap turn stop.
Brackets and removable metal enclosure on extension column.
Indicator (pointer).
Hand-operated spare.
Split stem packing.
Pressure relief hole in the cap.
Standard fittings for sealing grease.
Taper plugs for water bleed-off and safe decompression.
Filter (on pneumodrive and pneumohydrodrive) for moisture drain.
Technological advantages
Low hydraulic resistance coefficient
Pipeline cleaning and diagnostics can be performed without removal of valves.
Seats are in constant contact with the gate that is protected from operating fluid caking and has sustained integrity both on inlet and outlet (double acting seats).
High wear resistance.
Integrity can be restored (if required) in operation.
Precise alignment of the plug relative to pipeline axis in on and off positions.
Piping system protection.
Gate position is easily pinpointed.
Good visibility from high altitude.
Possibility (in no-current state) for opening and closing of the valve.
Possibility to safely replace the soft stem seal on the active gas pipeline.
Reduced force on control device.
Quick connection of stuffing box sub.
Air bleeding from the valve.
Quick replacement of adsorbent cartridge in operation
At the customers request, main parts of the valves can be manufactured of carbon corrosion-resistant steel or titanium alloy.
Both single-piece and knock-down valve bodies are offered.

Parallel-slide gate valve DN 500-1200 PN 8,0-12,5 MPa, 3741-007-05749375-2005
Design features
Full-opening body.
Double seal (primary - metal-metal, secondary metal-elastomer) on o-rings of the body.
Corrosion-resistant gate that is in constant contact with o-rings of the body.
Drain line inside the valve.
Removable polyurethane o-rings and clamp connection body-cap.
Stuffing box rings are made of thermal-expanded graphite.
Technological advantages
Low hydraulic resistance coefficient.
Pipeline cleaning and diagnostics can be performed without removal of valves.
Improved reliability and longer service life.
O-rings and valve interior are protected against abrasive wear, settlings and caking of operating fluid.
Settlings can be removed from the valve body.
High degree of maintainability.
Reduced frictional wear of the stem.
Long service life of the stuffing box.
The valve design has additional advantages:
- Protection of drain pipeline from damage and freezing in winter time;
- Simple design of seats, easy repair;
- Removable o-rings are replaceable;
- Quick-removal clamp connection that allows to reduce time for valve assembly;
- Threaded end of drain pipe bypass that allows to connect dewaxing unit and outlet hose. The hole for the drain plug can serve to measure leaks.
- The valve can be repaired without removal from the pipeline.
