Components of pipeline
1.Safety valve: protects the system components against excessive over-pressure in all operating phases.
2.Ball valve,check valvebrass material
3.WILO pumpthis pump is a standard device in the system,it required operating point can be preselected using one of the three levels.
4.Manometeradopt hydraulic aseismatic manometer with a range from 0 to 10 bar indicates the system pressure.
5.Connect of expansion vessel: install expansion vessel,avoid the system working at minus pressure.
6.Flow sensortimely monitor medium flow of the whole system..
7.Exhaust settingadopt spray-paint steel tube, it can release air cause of medium flow in the pipeline. According air quantity and frequency which cause of system, we can examine whether this system have leakage phenomenon.
8.Pipeline temperature display: medium temperature between right trip and return trip, can be displayed at first time. Temperature sensors are packed in a tube, Do not need to turn off any parts when replace it.
9.Medium inletturning the handle 90° to left so that medium can be injected in it..
10. Heat preservation materialEPS
11. Screw thread1/2inch.
12. Maximum working temperature of pipelineflow tripmanometer side150
return trippump side110

Installation
Vertically installation,installed at flow and return trip of collector and water tank. As above picture.

Advantage
A.Designed for self-sustaining solar operation
B.Easy installation, save cost, beautiful appearance
C.Easy to check the flux of pipeline, temperature display.
D.Constant air separation during line operation,check system whether have leakage.
