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
