➀
Models are limited to maximum temperature rating of
selected switch mechanism.
➁
Minimum specific gravity ratings apply to single stage
units only. Consult factory for two or three stage units.
¬
Models V35 and Z35 contain 17–7 ph stainless steel
floats.
➃
Codes for a 16-inch center to center dimension are
applicable to Models G35 with 600# flanges and Z35
with 600 & 900# flanges only.
➄
Process temperature based on +100° F (+38° C) ambi-
ent.
➅
For models built to ASME B31.1 in applications over
+750° F (+399°C), 100% radiographic examination is
required. Consult factory for pricing.
∆
HS switches can be used with only materials of con-
struction code 1 on models V35 & Z35
