Typical CP200 Series Cut-away View Introduction The CP200 Series pressure loaded regulators have been engineered to fit a multitude of pressure reducing applications including commercial and industrial installations. The CP200 Series provides accurate control for use in pressure factor measurement (fixed factor billing) applications. This flexibility is provided by the various body end connection sizes, outlet pressure settings, and orifice sizes. 2 Overpressure Protection Options Available: • Token Relief—Provides a small capacity or token relief located in the Type 67CPR pressure loading regulator that relieves minor overpressure caused by thermal expansion or minor nicks in the orifice or disk. • Secondary Seat™ Protection—Provides lockup via a secondary seating and disk surface in the event that damage to the primary disk or orifice seating surface, or debris in the flow path, inhibit primary lockup. Secondary Seat protection does not provide additional overpressure protection in the event the secondary seat or disk is damaged by debris or contamination in the pipeline or from conditions that would cause the regulator to go wide open. See page 6 for additional information.
