Introduction
Scope of the Manual
This instruction manual covers operation, installation,
maintenance and troubleshooting for 2000 Series
Temperature Regulator.
Product Description
The 2000 Series is a self-operated temperature
regulator available with single or double seat in direct
or reverse acting. It is also available with two seat
areas for three-way mixing. This regulator provides
economical temperature control of a storage heater
and open topped tank heater.
Principle of Operation
The 2000 Series Temperature Regulator controls
the flow of the media passing through its valve by
responding to temperature changes at the temperature
bulb. The valve is made up of two assemblies: the
valve body and the thermal system assemblies.
The thermal system of the 2000 Series temperature
regulator consists of a temperature probe (bulb),
pressure chamber (bellows) and a length of tubing
(capillary) which connects the two. A liquid is sealed
inside the thermal system. For each temperature
range, a specific liquid is used.
