Flowserve
Applications:
Decoking, Petroleum Production and Refining
Industries:
Heavy Oil and Upgrading, Delayed Coking
Three Distinct Functions
- Recirculation (bypass) flow control for pump protection
- Pre-fill of decoking lines, hoses, manifolds, etc., 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
