Ball Valve Type TBV

• Design according to DGRL 2014/68/EU, API 6D or API 6A
• Entirely metallic sealing systems
• O-bubble leak rate
• Three part housings (split body) or block design made of forged material
• Depending on the nominal width with trunnion-mounted or float-mounted spheres
• Blowout-safe operating spindle
• Float-mounted, self-centering seat rings with pretensioned spring elements
• Automatic housing pressure relief (with trunnion-mounted spheres)
• Sealing force dependent on line pressure
• Double block and bleed (with trunnion-mounted spheres)
• Exchangeability of upper operating spindle seal at full line pressure
• No electrostatic charge-up
• Fire safe according to DIN EN ISO 10497 / API 607
• Maintenance free
