Flowserve Decoking Control Valve (DCV) for Decoking Systems

The Flowserve Decoking Control Valve (DCV) features a proven, simple design with minimal moving parts to provide cost-effective, trouble-free operation. This single valve controls the flow from the high-energy jet pump and provides three distinct functions: Recirculation (bypass) flow control for pump protection Pre-fill of decoking lines and hoses at a predetermined flow rate to prevent water hammer Full flow to the decoking tool nozzles. Very low pressure drop (high Kv [Cv]) in full flow for reduced energy consumption When maintenance is required, the DCV’s cartridge design allows for quick change-out without the need to disconnect any flow path flanges. Depending on site set-up, this change can be accomplished in less than one shift, reducing downtime and minimizing maintenance costs. Flowserve’s decoking system is fully integrated.
