straight heating valves, 1 inch motorized zone valve for heating
flow control
Product Description
Our DC motorised valve 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. Its pressure rating is PN16, more
than 100,000 cycles life cycles. 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 |
