Venn RC-47N type Door To Door Water Pressure Reducing Valve/Check Valve
Manufacturer: Venn Co., Ltd.
Model: RC-47N
Features
It uses chlorine-resistant EPDM.
In addition, it features a hygienic design with no liquid pooling.
Moreover, it operates reliably from low to high differential pressure.
Furthermore, it adopts a new, simple test gag method.
As a result, water pressure tests can carry out even after installation.
Maintenance is easy thanks to the cassette design.
Finally, because there is no caulking or welding, all parts can easily sort and recycle.
