What is a Temperature Regulator?
Described as a Self-Acting temperature control. They are designed to automatically control the flow or steam or liquid, in response to any temperature changes in a cooled or heated product, and keep the product temperature at a constant predetermined level. These Automatic Self-Acting temperature regulators require no electricity or pneumatics for operation. They have no need for any external resources to keep them operating. Power or Pneumatics failures will not affect their continued operation.
How does a Temperature Regulator work?
Self-acting type of temperature controls use the expansion of temperature sensitive material encapsulated in a sensor which is attached to a capillary, this moves the valve via an attached push rod. When the sensor is immersed in the product it relays any temperature change via the capillary through the expansion or contraction of the temperature sensitive material in the sensor/capillary. For heating applications you would utilise a normally open valve (Direct Acting), typically you would use steam or hot water to raise the product temperature in a heat exchanger or tank etc. As the product temperature rises toward the set point the valve will move toward the closed position, limiting the amount of heating media into the heat exchanger. For cooling applications, this time via a normally closed valve (Reverse Acting) you typically would use cold water or other cooler fluid to cool down the temperature of a product in a heat exchanger or tank. As the product temperature rises toward the set point the valve will move toward the open position, allowing cooling media into the heat exchanger. Although slow to react to sudden, large changes in demand they perform extremely well under steady load conditions, settling into control, proportional to the difference between the desired/set value and the measured value and are not limited to being fully open or fully closed. Usually available with various temperature ranges.
How long will my Temperature Regluator last?
This really depends upon the environment and the quality of the steam and fluids that the regulator operates with. The installation of an upstream strainer is highly recommended to reduce the amount of dirt and other impurities from contaminating the valve internals. A correctly selected and sized temperature regulator with a good maintenance regime, should perform for many years. Obviously it should be installed in accordance with the manufacturer's recommendations and it is highly recommended that regular inspection for correct operation is carried out. If found to be faulty it should be cleaned and or repaired as required. This will give the valve the best opportunity to continually operate satisfactorily for many years. When a temperature regulator does fail, it can lead to a loss of production and or a waste of energy, fuel bills can increase.
How do I install a Temperature Regulator?
It is vitally important when selecting and sizing any type of regulator, that certain criteria is met. Such as the operating pressure/temperature, the duty required, the application etc. Temperature Regulators should always be installed in accordance with the manufacturers recommendations and in accordance with good steam fitting practice. In Particular always insure; Correct direction of flow, Correct orientation and make sure they are well supported and leave clear access for general maintenance and repairs. Installation of a strainer on the upstream side is highly recommended to give protection from dirt and other impurities. A temperature Regulator is usually made up of 2 main parts; Normally a 2 port valve which will require a temperature controller and attached suitable capillary with sensor. The capillaries are available in various lengths (2 metre standard) and the sensors tend to be larger than other more sophisticated types such as pneumatic and electronic equivalents, they are also much slower to react to sudden temperature change. Although the thermal bulb can be mounted in any position, make sure that at least 3/4 of its total length is in direct contact with the product to be heated or cooled. The temperature regulator usually has an adjustable scale to set a temperature against, whilst having the ability to maintain a constant temperature under steady load conditions the actual set point should be checked against a separate thermometer installed in the product to be heated, installed in a location as close as is possible to the sensor of the regulator.
What are typical uses of a Temperature Regulator?
For best results, applications would be non critical, with low, steady, flow rates. Well suited for those with limited resources, as you only need a one trade for installation, no electrical or pneumatics required. These valves are usually very robust and extremely reliable. Simple to size and select. Many options are available, such as different capillary lengths and operating temperature ranges. The control is ‘stand-alone’, and cannot communicate with a remote controller or PLC (Programmable Logic Controller). Typical applications such as jacketed pans, Tracer lines, boiler feedwater tanks, hot water calorifiers, acid baths etc. Also Used as a cooling control for boiler blowdown vessels etc.
How long will my product take to get to me?
This depends upon where you are based and the freight method chosen. If the express freight option is selected it is usually next day delivery to metropolitan areas in Australia for under 5kg. If free freight has been selected it will go by road freight which can be anywhere from 1 to 10 days depending upon your location. It usually averages 3 days.
What warranty do I get?
All of our products come standard with a 12 month warranty. The good news is we have very strict quality controls and all valves leave our warehouse tested and inspected so there are rarely any issues.
