Series VT-BV-T

Series VT-BV-T

The Vahn-Tech Series VT-BV-T is an API 6D compliant and monogrammed trunnion mounted ball valve available in standard pipeline soft-seated configuration, as well as specialty metal-seated, high-temperature, acid gas and CO2 configurations. Seats designs can be configured as Single Piston Effect (SPE) and Double Piston Effect (DPE), providing verstatility to suit any application requirement for Double Block & Bleed and Double Isolation & Bleed.

The seat insert for soft seated configuration is made of thermoplastic material with multiple options depending on the actual operating conditions

Designed and manufactured to meet the requirements of API 607 & API 6FA and to prevent both internal and external leakage in the event of a fire

Blow-out proof design of the one-piece stem includes a step preventing blow out, even during maintenance operation or incidental cavity pressure rise

To prevent static sparks – antistatic devices (ball loaded spring/springs) are assembled between stem and ball to permit electric conductivity through all metallic components

Double Isolation and Bleed (DIB) design, with seat(s) designed for 'Double Piston Effect', allowing each seat to provide a seal against pressure from a single source in both directions

Designed to meet the most stringent Low Fugitive Emission requirements; tested to meet ISO-154848 fugitive emission requirements

Cryogenic ball valves are available in all sizes and pressure classes for operating temperatures from -196°C to +120°C

Metal seated ball valve design for high temperature and hot gas applications up to 550°C / 1022°F

Special high-pressure, high-temperature O-ring options to withstand rapid gas decompression, commonly referred to as AED (Anti-Explosive Decompression)
