Dual Expanding Plug Valve

Zero leakage – non abrasive sealing
The sealing principle of most valves, e.g. gate, butterfly and ball valves, is based on shear or friction force. This causes gradual
wear of the sealingmaterial and increases the required torque to open or close the valve, especially when the valve is automated.
The unique sealing mechanism on the dual expanding plug valve is designed so, the slips retract, preventing abrasion of the
elastomer seals during operation. This ensures long seal life as well as a lower opening and closing torque requirement and
prolongs the overall life of the valve.
Fugitive emission certified
The VE
®
Dual Expanding Plug Valve is TA-LUFT FUGITIVE EMISSION Certified, complying with the stringent
ISO 15848-1 2006 Annex B, to the highest stability grade C03. The VE
®
Dual Expa nding Plug Valve provides not only a
“zero-leakage” solution but also safe-guards the environment, in full compliance with the latest emission regulations.
Innovative lower trunnion design
The VE
®
Dual Expanding Plug Valve has a special designed lower trunnion, which prevents accumulation of particles and dirt
in the lower part of the valve body. This accumulation could otherwise cause malfunction of the plug-system. Our unique lower
trunnion design minimizes this effect securing a consistent and reliable operation of the valve.
