On all “D” (Direct Acting) types, an increase in the temperature of the control agent causes an
increase in output pressure of the operating medium from the pilot controller. On all “R”
(Reverse Acting) types, an increase in the temperature of the control agent causes a decrease
in output pressure of the operating medium from the Pilot controller.

TYPE DESCRIPTION
D-2 Direct Acting - Fixed Proportional Band. Air, non-corrosive gas or water as
operating medium.
R-2 Reverse Acting - Fixed Proportional Band. Air, non-corrosive gas or water as
operating medium.
DQ-2 Similar to D-2 except larger pilot valve porting permitting the use of water or
other non-corrosive liquids of low viscosity as operating medium or higher
volume output for air or non-corrosive gas as operating medium.
RQ-2 Similar to R-2 except larger pilot valve porting permitting the use of water or
other non-corrosive liquids of low viscosity as operating medium or higher
output for air or non-corrosive gas as operating medium.
DTP-2 Direct Acting - Adjustable Proportional Band. Air or non-corrosive gas as
operating medium.
RTP-2 Reverse Acting - Adjustable Proportional Band. Air or non-corrosive gas as
operating medium.
DTHP-2 Similar to DTP-2 except constructed for higher adjustable temperature range.
RTHP-2 Similar to RTP-2 except constructed for higher adjustable temperature range.
