3 port motorized zone valve, central heating zone valves with DC actuator motor
Product Description
The new DC motorised valve is with pressure rating is PN16, more than 100,000 cycles life cycles. It can attached to IC card prepay water meter, AMR water meter, or used to control the flow of hot water in a central heating system. The motorised valve can be used for control of both heating and hot water, and it works by controlling the flow of water from the heating boiler to other parts of the system. We produce the best mini motorized valve. If the ball valve motor fails, the electric motorised valve will not open. The valves will not then close the end switch and so will not complete the auxiliary circuit. It will prevent the boiler firing and the pump running when there is no water circuit open.
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 |
