Gate Valves

• ANSI B16.34
• 2" to 36"
• ASME class 600 to 4100

• Pressure seal body-bonnet joint - Line pressure is used to create a tight body-bonnet seal. Higher the pressure, tighter the seal
• Parallel-slide gate with disc-springs - Better sealing, lower operating torque, minimises possibility of disc jamming
• Fully hard-faced trim - Disc, seat-rings and back-seat hard-faced for longer service life
• Welded seat ring - Eliminates leakage path between seat ring and body, does not loosen up due to temperature fluctuations or vibration
• Valves available in intermediate pressure classes (#3100, 3500 & 4100) to meet specific customer requirements
• Option - Valves are offered with pillar yoke arrangement that provides easy access to gland packing

• ANSI B16.34
• 2" to 18"
• ASME class 600 to 4100

• Y-type Configuration - Straight flow and lower pressure drop compared to conventional globe valves
• Pressure seal body-bonnet joint - Line pressure is used to create a tight body-bonnet seal. Higher the pressure, tighter the seal
• Integral body seat
• Fully hard-faced trim - Disc, seat and back-seat hard-faced for longer service life
• Guided disc
• Impactor hand wheels for tighter sealing
• Valves available in intermediate pressure classes (#3100, 3500 & 4100) to meet specific customer requirements
• Option - Valves are offered with pillar yoke arrangement that provides easy access to gland packing

• ANSI B16.34
• 2" to 28"
• ASME class 600 to 4100

• Pressure seal body-cover joint - Line pressure is used to create a tight body-bonnet seal. Higher the pressure, tighter the seal
• Fully hard-faced trim - Disc and seat-rings hard-faced for longer service life
• Welded seat ring - Eliminates leakage path between seat ring and body, does not loosen up due to temperature fluctuations or vibration
• Swing-type disc
• Disc: Internally-hinged - No opening on the body, higher integrity
• Valves available in intermediate pressure classes (#3100, 3500 & 4100) to meet specific customer requirements
