Second layer of protection ensuring maximum safety for insertions and retrievals of corrosion devices while under pressure up to 3600 PSI.
The Cosasco Double Block and Bleed Service Valve is designed to provide an extra layer of protection to ensure maximum safety requirements are met. It is compatible with all Cosasco Access Fittings and RBS/RBSA/RSL Retrievers. Attached to the access fitting body, the primary valve is the control which allows the pressurized product to enter the retriever during insertion and removal of Cosasco Solid or Hollow Plug Assemblies. It also contains the pressurized product when the retriever is disconnected. The secondary valve acts as a back-up in the unlikely case the primary valve leaks or fails.
