Features
- Main components are forged.
- Three bonnet seal types available: bolted bonnet (with wound gasket), welded bonnet (threaded and fully welded), and pressure self-tightening seal structure.
- Bolted bonnet sealed with wound gasket (stainless steel wire with flexible graphite); metal ring connection available on request.
- Welded bonnet uses threaded connection with full weld; fully welded connection available on request.
- CL900, CL1500, and CL2500 middle cavity uses pressure self-tightening seal-sealing performance increases with internal pressure.
- Smooth flow channel with low flow coefficient.
- Sealing surface less susceptible to erosion from media.
- Sealing surface made of alloy steel or hard alloy for wear and abrasion resistance.
- Flexible graphite packing for reliable sealing and light operation.
- Bidirectional flow with no disturbance or pressure reduction.
- Gland packing can be replaced with the valve isolated and depressurised
- Simple geometry, short face-to-face length, wide application range.
Description
Compact forged steel gate valve with main components manufactured by forging. Available in three bonnet seal types: bolted bonnet (sealed with wound gasket of stainless steel wire and flexible graphite, with metal ring connection available on request), welded bonnet (threaded connection with full weld, fully welded connection available on request), and pressure self-tightening seal structure for Class 900, Class 1500, and Class 2500. Sealing surfaces of alloy steel or hard alloy. Flexible graphite packing. Bidirectional flow with no pressure reduction. Gland packing can be replaced under online shutdown conditions without affecting system operation.
Selection notes
This forged steel gate valve is a compact forged steel valve pattern, supplied for socket weld, threaded, flanged and butt weld installation.
Sizes run DN6 to DN80, in Class 150, Class 300, Class 600, Class 900, Class 1500, Class 2500.
The body is offered in Carbon Steel, Stainless Steel and Alloy Steel, so the grade can be matched to the service rather than the other way round.
Stated service media include tap water, sewage, petroleum, chemical media, textile process fluids and energy system fluids.
It is catalogued for Water & Wastewater and Oil & Gas.
Working temperature is -196°C to 600°C.
Built to API 602, BS 5352, GB/T 12224, ASME B16.10 and GB/T 12221.
Supplier remarks
- Metal ring connection can be used when customers have special requirements.
- Fully welded bonnet connection can also be used when customers have special requirements.
- The length of the riveted structure at the threaded end of the socket-welding connection shall comply with the factory standards.
