polypipe underfloor heating zone valve, manual override temperature control valves
General description
Our manual override motorized ball valves consist of mini motorized ball valve, motor actuator (3 wires 2 points control, or customized). The zone valve on flow, returns joined together with cylinder. The complete range of underfloor heating temperature control valves to suit many of your underfloor heating applications and can be supplied to fit most underfloor heating pipe sizes.
Our 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 |
