heating ball valve, two port motorized valve for hot water flow control, HVAC
Product Description
The zone valves internally consists of a motor to move the ball valve to the open position, a spring to return it to the closed position, and a microswitch which is activated when the valve is fully open. In a heating system when heat is required, power is applied to the motor to open the valve by the thermostat detection.
Application
Advantages
No | Name | Material | Advantage |
1. | O-ring | Import fluoro rubber (green) | 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 2. Minimal deformation, polish surface, wearable |
7 | 0-ring | EPDM | 1. Good elasticity, as buffer after Teflon washer to improve seal effect 2. Reasonable structure design, ensures perfect holding margin |
