Repair & Replacement Parts For Clear UPVC Union Ball Valve

These transparent UPVC spare parts are designed as compatible replacement components for our soft wash metering valve series. Unlike standard opaque valve bodies, the transparent housing lets cleaning contractors visually check liquid flow status, spot particle buildup and observe chemical mixing condition directly without taking the whole system apart. Operators can catch early signs of contamination or partial blockage during daily jobs, so small issues can be handled ahead of time to avoid unexpected downtime.




When paired with our main soft wash metering valve Soft Wash Metering Valve, these transparent spare parts extend the service cycle of your existing valve unit. Instead of replacing the complete valve once certain housing parts wear out, users only swap these individual transparent components to restore normal working condition, which helps cut long‑term equipment operating cost. They fit well for residential roof cleaning, exterior wall soft wash and other low‑pressure liquid dosing projects, bringing extra visibility for chemical proportioning work on every job site.

Additional Product Notes

These transparent UPVC spare parts work with DN15, DN20 and DN25 sizes of our soft‑wash metering valves. When reassembling your valve, pick EPDM or FKM(Viton) O‑rings based on what chemicals you are using. Stick with EPDM for neutral cleaning fluids. Go for FKM when you handle harsher soft‑wash chemicals.

One thing to note: transparent UPVC does not hold up well under constant direct sunlight. If your equipment sits outside, add some sun shielding. This will slow down discoloration and material wear.

Maintenance Guidance

Give these transparent parts a quick check every three to six months. Look for surface cracks, leaking seals, and dirt or sediment building up inside. When you notice crystals or debris built up inside, flush it out with mild cleaning fluid that works with UPVC. Never scrape inner walls with hard tools. Scratches will ruin transparency and shorten part service life.

While installing these spares onto your existing valve, do not crank down the union nuts too hard. Overtightening can crack the clear UPVC housing. If you take apart the inner PVDF ball and PTFE valve seat during replacement, double‑check and reset your dial scale afterward, so you get correct flow readings again.
