Product Description
Our brass/stainless steel heating ball valves are specifically designed to withstand internal temperatures as high as 150°C to limit contaminant buildup and reduce system maintenance. It can be opened or closed by an electric motor actuator, or manually in case of no electricity.
Application
Advantages
No | Name | Material | Advantage |
1. | O-ring | Import | Resistance to high temperature, oil, corrosion, chemicals, Work temp.: —30℃+280℃.Quadruple seals, minimize the risk of leakage. |
2. | Drainage | Drain just in case leakage happens | |
4 | 0-ring | EPDM (red) | Between nut and valve body, extra external leak proof, reduce the possibility of internal leak |
8. | Ball | Brass or SS304 | Finely polished, rack nickel plating (not barrel plating), smooth surface, improved torque performance |
9. | Water proof G | Avoid water into housing, seal between valve body and valve housing |
No | Name | Material | Advantages |
5. | Wall thickness | 2.0mm, PN20 | |
6. | Teflon washer | Import teflon | 1. Import teflon tube, numerical processing to perfectly match with ball surface |
7 | 0-ring | EPDM | 1. Good elasticity, as buffer after Teflon washer to improve seal effect |
