Change Under Pressure (CUP) Sealing Assemblies

Change Under Pressure (CUP) Assemblies provide a safe way to seal a sampling probe, test coupon and/or temperature probe inserted into a pressurized environment. This system allows changes to be made under pressure without downtime or loss of pressure and with minimal process fluid spills. Conax Technologies CUP assemblies are designed for use with gate or ball valves. These assemblies generally utilize PG Series glands with the appropriate sealant for the application. Assemblies can be configured with different mounting thread sizes and bore sizes and normally include a full port valve to allow vessel access and a drain valve to allow release of pressure/fluid. CUP assemblies can be ordered with or without the sensor assembly. Blow-out collars, safety chains and/or redundant seals can also be provided to meet application requirements. Pressure Limit: The sealant will withstand several thousand psi pressure but operation is normally limited by the force required to slide the sensor assembly into a pressurized system. Temperature Range: Dependent on the sealant used.
