Isolation Valves
High-Performance Coker Isolation Valve
The DeltaValve coker isolation valve sets a higher standard for reliability and performance in high-temperature, dirty service applications. Specifically designed for coker operations, it maximizes efficiency, reduces maintenance, and supports sustainability initiatives. This valve is built to withstand the demanding environments of delayed coking units.
Featuring an anti-fouling design with gate containment plates, the valve traps process media within the gate’s orifice, ensuring maintenance-free operation. Self-cleaning, live-loaded metal seats provide a tight shutoff, reducing steam consumption and associated costs. Its top-entry design allows for in-line servicing without removing the valve, making it ideal for a range of delayed coking applications.
