Venn RC-47N type Door-to-door water pressure reducing valve/check valve (for water / hot water)
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.
