Virgo SS Series Floating Ball Valve

Virgo

The Virgo SS Series Floating Ball Valve utilizes a live loaded stem design to ensure additional protection against leakage even at very low pressures. The triple stem seal utilizes a combination of O-rings and packing materials to provide a leak-proof seal and to minimize fugitive emissions. Other features such as double body seals, blowout-proof stem, fire safe design, body cavity pressure relief, and built-in anti-static devices help to maximize the safety of the valve.

Features

  • MULTI-SEAL STEM - The triple seal utilizes a combination of O-rings and packing materials to provide a leak-proof seal and to minimize fugitive emissions. Live loaded system design ensures additional protection against leakage through the stem housing even at very low pressures.
  • DOUBLE BODY SEALING - Ensures positive body joint sealing against pipeline stresses
  • ISO MOUNTING PAD - Incorporate ISO 5211 top pad which simplifies actuator or gear operator mounting
  • 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
  • BODY CAVITY PRESSURE RELIEF - Valve is designed to relieve pressure from body cavity pressure when valve is opened. This feature is also available for closed position.
  • 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
