Zero leakage with double block and bleed full metal sealing
Features
Steam purging in seat area for continuous protection and cleaning, bearing protection as an option
Two piece shaft design for maximized capacity
Patented position indicator for highest process safety
Double block and bleed (DBB) sealing system for hydrocarbon and oxygen segregation
Compact and solid design
100% fluid segregation
Block function with steam
High corrosion and abrasion resistance
Cobalt based alloy sealing surfaces and disc edge protection
Fire safe design
Gate valve face to face length
Benefits
High operational reliability, best thermal expansion resistance - works in all process conditions
Maximized process uptime, faster transition to decoking mode and fast operation
Compact and low weight construction – no extra piping support needed
Flexible plant design - suitable for all installation directions and high temperatures up +600 C
Zero leak construction prevents the back flow of the process gas to cracker furnace
Minimized OPEX - maintenance free up to 5 years
Optimized maintenance process for maximized process uptime
