Reliance RWC 107 Series Pressure Relief Valve 1/2" x 1/2" F x F 6 Bar - PREL107010
The PREL107010 Potable Water Pressure Relief Valve is designed to safely discharge water from the system when cold water over-pressurisation occurs in an unvented cylinder. The Reliance Valves 107 Series Potable Water Pressure Relief Valve offers essential protection for unvented systems against the dangers of over-pressurisation. Each valve is pre-set and locked to a specific pressure; if the system's pressure surpasses this threshold, the valve will lift off its seat, allowing water to be discharged safely to waste. This makes it the primary safety device in an unvented system. The valves are available in pressure settings from 3.5 to 6 bar, along with various connection sizes to accommodate different installation requirements.
Features and Benefits:
- Diaphragm design enhances resistance to scale build-up
- Provides reliable protection against over-pressurisation
- Various connection options allow for flexible installation
- Set relief pressure range between 3.5 and 6.0 bar
- Designed exclusively for cold water applications
Specifications:
- Size: 1/2" x 1/2"
- Connections: BSP Female Inlet x BSP Female Outlet
- Materials: Hot pressed DZR Brass
- Medium: Water
- Set Pressure: 6 Barg
- Temperature: Up to +110°C
