The design of the Virgo™ TOV provides a non-rubbing, open/close operation. Unlike conventional butterfly and gate valves, whose seats are chafed with every stroke, the Virgo TOV uses a triple offset design to prevent seat wear. This means superior performance, lower maintenance, and a longer life for your valves. The versatility of the design allows for use in large variety of applications and within a broad range of operating temperatures.

METAL-TO-METAL ’ZERO’ LEAKAGE - Laminated resilient seal ring flexes to give uniform wedging effect and API 598 leakage requirements. Resiliency of seal ring allows for the valve body and disc to expand or contract relative to each other withou
LOW EMISSION SHAFT SEAL - Adjustable shaft packing with multiple graphite rings located between two anti-extrusion rings control fugitive emission and give longer packing life. Gland packing with live loading is available as an option.
EXTERNALLY RETAINED BLOW-OUT PROOF DESIGN - Engineered gland design gives shaft blow-out proof protection externally, conforming to the requirements of API 609, (Category B).
EXTERNAL INDICATOR FOR DISC POSITION - Disc position is indicated by dimple on shaft. When the dimple is in-line with flow axis, disc is open.
BEARING PROTECTION - Graphite ring in bearing ensures protection against ingress of line media in to the bearing surface and thus avoids jamming of shaft
ONE-PIECE SHAFT - One-piece shaft is guided by long bearings, which are placed nearer to disc for close support. Bearings are super finished and nitrided for trouble free life. Within the pressure boundary area, the shaft design provides added strength.
STANDARD MOUNTING - Bracket top side drilling and shaft connection as per ISO 5211
