In order to produce consistent flow quantity for stable operation, the pressure drop across both flow paths (inlet to outlet) must be equal. Do not use for steam applications.\u003c\/p\u003e\u003cp\u003eThe W91 \u0026amp; 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.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eModel W91 Non-Indicating (Without Indicating Dial) features a lower profile and should be specified where space constraints may be an issue.\u003c\/li\u003e\n\u003cli\u003eModel W94 Temperature Indicating (With Indicating Dial) will allow the operator to verify the process temperature and to aid in temperature adjustment.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow It Works\u003c\/h2\u003e\u003cp\u003eThe \u003cstrong\u003eW91\/W94 Temperature Regulator\u003c\/strong\u003e is a fully self-contained unit requiring no external power source (i.e., compressed air or electricity). Regulation takes place when the sensing element (bulb) of the thermal system is exposed to changes in temperature. The thermal system is charged with a predetermined amount of vapor fill, which, when heated, will cause the bellows within the unit’s actuator housing to expand. The valve action is either In-To-Close for Heating or In-To-Open for Cooling.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e3-Way Valves\u003c\/strong\u003e are used for mixing two flows together, or for diverting a flow to or around a device (bypass). In order to produce consistent flow quantity for stable operation, the pressure drop across both flow paths (inlet to outlet) must be nearly equal. The Sleeve-Type (common port on the bottom) is most commonly used for diverting applications; however, due to its design, it can also be used for mixing applications (NOT for steam use). It is also suitable for water or glycol type service, up to a maximum temperature of 300°F. A higher temperature O-ring for use with other fluids, such as oil, or for temperatures up to 410°F, is available.

Single-Seat In-To-Close, all Double-Seat, and all 3-Way valves have a recommended working span in this part of the nominal range.
