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.
- Packing can be replaced and maintained during online shutdown without affecting system operation.
- Simple geometry, short face-to-face length, wide application range.
Notes
- 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.
Description
A forged steel gate valve with main components manufactured by forging, offering higher mechanical properties than cast steel equivalents. Available in three bonnet seal types: bolted bonnet, welded bonnet, and pressure self-tightening seal structure. Suitable for bidirectional flow with no pressure reduction and operates across a wide pressure and temperature range.
