RMC Pressure Limiting Valve with Dual Check — 350 kPa (PVDC503)
RMC’s Pressure Limiting Valve with Dual Check combines backflow prevention and pressure limiting through independently acting mechanisms in a single device. It’s designed to be installed in the water supply pipework immediately upstream of domestic water filter units.
Why Choose This Valve?
- Two functions in one — pressure limiting + dual check backflow prevention.
- Integrated design — reduces the need for additional flow and pressure limiting devices.
- Install flexibility — suitable for horizontal or vertical installation.
- Individually tested — quality assurance built in.
- Built tough — dezincification resistant brass and high-quality polymers.
- Residential / low hazard use — designed for residential containment control (refer AS/NZS 3500.1).
