Reliance RWC 104 Series Pressure Relief Valve 1

Reliance RWC 104 Series Pressure Relief Valve 1" x 1.1/4" F x F 8 Bar - PREL104017

The PREL104017 High Capacity Potable Water Pressure Relief Valve is designed to safely discharge water from the system when cold water over-pressurisation occurs in an unvented cylinder. This high-flow valve suits larger capacity systems, protecting them from the risks associated with excessive pressure. The Reliance Valves 104 Series High Capacity Potable Water Pressure Relief Valve features a pre-set and locked pressure setting; if the system exceeds this limit, the valve will lift from its seat, allowing water to discharge safely into the waste system. The outlet connection is one size larger than the inlet, ensuring that the valve can manage a high-capacity discharge effectively. This valve acts as the primary safety device in an unvented system. Various pressure settings are available, ranging from 3.5 to 8 bar, along with multiple connection sizes to facilitate flexible installation.

**Features and Benefits:**

  • High-flow design ideal for larger capacity systems
  • Quick removal of the single-piece cartridge for easy cleaning or replacement
  • Diaphragm design enhances resistance to scale build-up
  • Provides essential protection against over-pressurisation
