92CT and 92CTP
The Type 92CT and 92CTP pilotoperated, direct-acting temperature regulators do not require an external power supply. They are used in heating applications where steam or hot water is normally the heating medium. With proper sizing, they are accurate within 3% of the maximum temperature set point at steady-state operating conditions. Both types use a Type 92T temperature control pilot. The Type 92CTP also uses a Type 6392 pressure-limiting pilot to prevent the downstream pressure from rising above its set point.
