Isolation and Bleed Valves
Customized decoking ball valves are used to manage cutting water flow to the coke drums and to relieve drum pressure. The valve designs incorporate unique features that provide long life and safe operations.
- Applications:
Petroleum Production and Refining, Decoking - Industries:
Heavy Oil and Upgrading, Delayed Coking
Features and Benefits
Isolation valves divert the cutting fluid to the correct drum scheduled for decoking while bleed valves relieve pressure on the closed drums. Valve material is specially optimized for long service life in decoking operations. ANSI 2500 RTJ flanges are standard with higher pressure ratings available.
Limitorque actuators with limit switches operate the valves and provide automatic control. A manual override is provided for operation in the event of a power failure. The valves include locking pins for safe position security during maintenance.
