CS200 Series
The CS200 Series direct-operated, spring-loaded regulators
have been engineered to t a multitude of pressure-reducing
applications including commercial and light industrial
installations. This exibility is provided by the numerous
body sizes, outlet pressure settings, and orice 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 simplied vent positioning, especially in tight spaces
or awkward installations.
To provide further exibility, the CS200 Series offers
optional overpressure protection via Internal Relief or
Secondary Seat
TM
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 Seat
TM
Protection provides shutoff in the event that
the primary orice seating surface or disk surface becomes
damaged or obstructed by debris and can no longer provide
shutoff. (See Figure on the following page)
