Single isolation fire-rated design for safe use with access fittings and retrievers for pressures up to 3600 PSI.
Cosasco 3600 FR Service Valve Kits are especially designed for internal corrosion monitoring and for use with Cosasco Access Fittings and RBS/RBSA/RSL Retrievers. Attached to the access fitting body, the 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.
Basically a ball-type valve with full-opening port, a special pressure equalizing port allows the operator to slowly release line pressure to the retriever. With pressure balanced on both sides of the ball, the difficulty or torque problems, even on high pressure systems. This kit will help to set up a total internal corrosion monitoring system with pipeline corrosion protection.
