Gost Pressure Seal Bonnet Industrial Gate Valves in Class 1500-2500
Design
Gate valve to DIN/EN with flanged or butt weld ends, pressure seal
design, body of forged or welded construction, non-rotating stem,
split wedge with flexibly mounted discs for precise alignment with
the body seats. Seat/disc interface made of wear and corrosion
resistant 17 % chrome steel or Stellite.
Application
Industrial plants, power stations, process engineering and
shipbuilding. For water and steam. Other non-aggressive fluids such
as gas or oil on request.
VALVE manufactures superior cast body, bolted bonnet OS&Y gate
valves in a variety of materials, trims, packing types, sizes (2"
thru 48") and pressure classes (150 thru 2500). The mechanical
characteristics make the wedge gate valve are ideal for
bi-directional "total flow system open/shut-off" applications with
minimal turbulance and pressure drop.
The valve design conforms to API 600 and B16.34. Face-to-face and
end-to-end dimensions conform to ANSI B16.5 and B16.25.
Gate Valve Benefits
- Little friction and minimal drop in pressure when fully opened
- Eliminates leaks
- Rising stem configurations make visual inspections easy
- Nonrising stem configurations are ideal for areas underground or
where space is limited
- Increase efficiency by saving energy when opening or closing a gate
valve
