The LTAP Series Low Temperature Actuation Probe is a temperature controlled pneumatic two-way valve. The device utilizes a pressurized copper probe which reacts to fluid temperature and opens a passageway in the top control head as the fluid temperature approaches the device temperature setpoint.
The LTAP Series can be installed on cryogenic systems to protect end users when draw rates are higher than system capacity or ambient conditions are much colder than normal. Factory pre-set at desired temperature — cannot be adjusted in the field.
- Highly Accurate: Setpoint tolerance of ±3°F
