An S200 Series regulator with an H or K (Figure 3) in
the type number can deliver air or gas at a higher outlet
pressure setting than the basic Type S201 (see Table 3).
S200 Series regulators with an H or K in the type number
have a heavy diaphragm plate, while most other
S200 Series regulators have a light diaphragm plate.
However, a regulator with a P in the type number will have
a light diaphragm plate for outlet pressure ranges under
1 psig / 0.07 bar and a heavy diaphragm plate outlet
pressure ranges over 1 psig / 0.07 bar.
An S200 Series regulator with a P or a PK in the
type number has a blocked turbo-booster tube, an
O-ring stem seal, and a 3/4 NPT control line tapping
in the lower diaphragm casing. A regulator with
a downstream control line is used for monitoring
installations or other applications where there is
other equipment installed between the regulator and
the pressure control point. The O-ring stem seal
helps separate body pressure from diaphragm case
pressure on monitor installations where leakage
cannot be tolerated.
