The 2-Way Self Acting Temperature Regulating Valves ( 2-Way T.R. Valve )are applied for temperature auto-control in heat exchanger, fuel oil preheating, central air and lubricating equipment, and have been widely used in mining factory, chemical industry ,hotel, building and marine etc.
The 2-Way T.R. Valves are designed according to the principle of liquid expansion. The sensor liquid will expand or contract with the temperature it detected, which will drive the valves to adjust the flow rate of the heating-media, and the temperature therefore is auto-controlled. Easily maintenance and without any extra power.
Normally opened 2-Way T.R. Valves for Heating System
The normally opened 2-Way T.R. Valve is mainly used in heating system, the combination of the valves and the thermostats has many selections, which can control different heating-media with different pressure. The technical parameters used in steam are listed in table 1, for other heat media,the table can also be used as reference.
Normally closed 2-Way T.R. Valves for Cooling System
The normally closed 2-Way T.R. Valve is mainly used in cooling system. The technical parameters of the valves assembled with thermostats
using in cooling water are shown in table 3 ,which are convenient for your selection.
Type Explanation
Q S F-65 B
①Body material
(Q-ductile iron, S-sus steel, C-bronze, G-steel)
②Seat type
( D-single seat, P-bellows balanced, S-double seat )
③Connecting way(F-flange ends)
④Nominal diameter (mm)
⑤Working way
(□Normally opened, don't indicated; B-normally closed)
Thermostat
Thermostat is reliable and well compacted, and can be used in hot water, steam and hot oil etc. the operation is based on the principle of liquid expansion, the sensor liquid expand or contract with temperature changing, the piston moving forward and backward accordingly, driving the T.R.Valve and the temperature is therefore controlled.
Note：
◆G with BSP thread, others'unit is mm.
◆sensor and cooling unit's material is stainless steel ,others' is copper.
◆Sensor length normally is 3M, but the lengths from 6M-12M are
available .
◆Threaded or welded protection pocket can be selected.
◆Safety working temperature should not be more than 40℃ of the
setting point.
◆Non-sensitivity:≤3℃.
Installation Note
◆To reach the best working condition, filter must be fixed before T.R.Valve.
◆By-pass valve should be installed in order for easily maintenance.
◆The pipe must be thoroughly cleaned before install T.R.Valve.
◆must follow the diagram shown on the right to select the correct fixing
direction according to the media temperature.
◆Sensor must be fixed to avoid vibration if using on the oscillating
equipments such as ships.
◆Because the capillary top part will move with handle, must be sure the
top part near the handle can move freely.
