The contraints related to steam cracking are :
1 – The thermal cracking phase of the process generates effluent with coke particules
2 – The decoking phase of the process generates coke particules which can drop into the valve body during the opening-closing phase and damage the sealing system.
Guichon Valves proposes a valve design with sliding gate and sleeve combination to reduce ingress of coke particules. The third generation of Guichon Valves’s transfer Line Valves, TLV03 (Transfer Line Valve), provides reliable, long lasting tight shut-off.
