Applications and Features:
The VTA 572 is a 3-way thermostatic valve for either mixing or diverting applications within hydronic closed loop systems. This particular non-electric thermostatic controller has a low temperature range providing an ideal control for a thermostatic changeover application, while providing a cost effective means to meet application demands. The VTA572 is available in two temperature ranges:
• 50 - 86°F (0 - 30°C)
• 68 - 109°F (20 - 43°C)

As a mixing valve supply through the VTA572 |
||
|
|
|
|
|
|
will enter from the left, mix with return water |
||
|
|
|
|
|
|
entering from the bottom and leave as mixed |
||
|
|
|
|
|
|
water from the right. |
||
Supply |
|
|
|
Mixed |
In a diverting application, water will enter from |
|||
|
|
|
|
|
||||
|
|
|
|
|
|
the right (Mixed) and depending on the set and |
||
|
|
|
|
|
|
sensed temperature will exit the valve as follows: |
||
|
|
|
|
|
|
1) Water temperature higher than set, flow will |
||
|
|
|
|
|
|
exit the Return port |
||
|
|
|
|
|
|
2) Water temperature is lower than set, flow will |
||
|
|
Return |
|
|
exit Supply port |
