The Virgo WL Series Welded Body Trunnion Ball Valve eliminates body flanges reducing potential leak paths and increasing resistance to pipeline pressure and stresses. The WL series design includes a robust fully welded forged body with multiple stem seals to eliminate leaks and meet demanding fugitive emissions requirements. The WL Series also features an API 6D monogram and ASME B16.34 wall thickness making it an extremely robust valve for pipeline applications.

Features

• MULTIPLE STEM SEALING – A multiple sealing stem features a triple sealing with two O-rings and a fire-safe gasket. This arrangement ensures consistent compliance with stringent fugitive emission testing requirements.
• SEALANT INJECTION – In the event of seat or seal damage due to contamination, an emergency seal can be formed using seat sealant injection.
• DOUBLE BLOCK AND BLEED – Spring loaded floating seats maintain contact with the ball and provide a tight shut off even at low pressure differential. Independent sealing of upstream and downstream sides facilitates draining/venting of the body cavity, thu
• EXTRA WALL THICKNESS – Increased corrosion allowance provides extra safety factor
• BI-DIRECTIONAL CLASS VI SHUTOFF – API tested leakage tested to ensure minimum maintenance and maximum valve life
• LOW OPERATING TORQUES – Valve features built-in ISO 5211 mounting and low operating torques for easy automation
• LOW PRESSURE SEALING – Compression springs provide uniform loading of seats, ensuring sealing at low pressures
• SAFETY DESIGNED IN- Safety features include internal anti-static device, blowout-proof stem provides positive stem retention, API 607/6FA fire safe certification, SIL3 capable
