CS200 Series Fisher® Commercial Service Reliability Typical CS200 Internal Relief The CS200 Series direct-operated, spring-loaded regulators have been engineered to fit a multitude of pressure-reducing applications including commercial and light industrial installations. This flexibility is provided by the numerous body sizes, outlet pressure settings, and orifice sizes. Ease of maintenance and installation is also a strength of the CS200 Series, which offers the combination of 360-degree rotatable union ring along with a rotatable upper casing that provides simplified vent positioning, especially in tight spaces or awkward installations. To provide further flexibility, the CS200 Series offers optional overpressure protection via Internal Relief or Secondary SeatTM Protection. By relieving gas through the diaphragm assembly to atmosphere, the Internal Relief valve minimizes downstream pressure build-up in the event of an overpressure situation. Secondary SeatTM Protection provides shutoff in the event that the primary orifice seating surface or disk surface becomes damaged or obstructed by debris and can no longer provide shutoff. (See Figure on the following page) Product advantages: • Internal registration provides compact installation • Multiple Overpressure Protection Options • Internal Relief • Secondary SeatTM Protection • Secondary SeatTM Protection with bleed • Wide range of NPT body sizes • Platform breadth and application coverage
