Typical Applications
The W91 & W94 Self-Operating Temperature Regulators are the preferred choice of original equipment manufacturers, mechanical contractors and specifying engineers. They require no external power source and are ideal for regulating the temperature of tanks, process streams and various types of industrial equipment. The Actuator is noted for its rugged die-cast aluminum housing, fully-enclosed bellows assembly and internal over-temperature range protection.
Model W91 Non-Indicating (without indicating dial) features a lower profile and should be specified where space constraints may be an issue.
Model W94 Temperature Indicating (with indicating dial) will allow the operator to verify the process temperature and to aid in temperature adjustment.
