Features

• Main components are forged
• Three bonnet seal options: bolted bonnet with wound gasket, welded bonnet (threaded + full weld), and pressure self-tightening middle-cavity seal
• Bolted bonnet sealed with stainless steel/flexible graphite wound gasket; metal ring connection available on request
• Welded bonnet uses threaded plus full-penetration weld; full-penetration-only option available on request
• Pressure self-tightening seal available for CL900, CL1500, CL2500, and CL4500
• Sealing performance increases with rising internal pressure
• Tortuous internal flow channel; higher fluid resistance than gate valve
• No relative sliding between disc and seating surface during opening/closing, reducing wear and extending seat life
• Flexible graphite packing for reliable sealing and light operation
• Unidirectional medium flow; installation direction must match arrow on valve body
• Packing can be replaced under system shutdown without removing valve from line
• Compact structure with short face-to-face length
• Reduced-bore design; most sizes are reduced diameter
• Maximum diameter generally not exceeding DN80

Notes

• Metal ring bonnet connection available when customers have special requirements
• Full penetration welded bonnet connection available when customers have special requirements
• Structural length for socket welding and threaded ends follows factory standard

Description

Forged steel globe valve with higher mechanical properties than cast steel equivalents, rated to NPS 1/4" - NPS 3" (DN6-DN80) and pressure classes CL150-CL4500. Available in straight-through (T-type) and direct-flow (Y-type) configurations with bolted bonnet, welded bonnet, or pressure self-tightening middle-cavity seal options. Flexible graphite packing is used throughout; medium flow is unidirectional.
