RMC 350kPa Pressure Limiting Valve with Dual Check – PVDC503

The RMC 350kPa Pressure Limiting Valve with Dual Check combines pressure limiting and backflow prevention in one compact unit. Designed for installation immediately upstream of domestic water filter units, it helps protect the filtration system from excessive supply pressure while preventing reverse water flow.

Independent pressure limiting and dual-check mechanisms operate within a durable dezincification-resistant brass body. Suitable for horizontal or vertical installation, the integrated design reduces the need for separate devices.
