The PREL102027 Reliance Water Controls (RWC) 102 Series potable water pressure relief valve is essential for discharging water from the system at a predetermined pressure, safeguarding against cold water over-pressurisation in unvented cylinders. Designed to protect unvented systems from excessive pressure, the Reliance Valves 102 Series Potable Water Pressure Relief Valves feature a pre-set and locked mechanism that activates when the system pressure exceeds the defined limit. At this point, the valve lifts off its seat, allowing water to be released safely to waste. Serving as the primary safety device in any unvented system, these pressure relief valves are crafted with a robust single-piece cartridge and are available in various pressure settings ranging from 3.5 to 8 bar, along with multiple connection sizes for versatile installation.

Features and Benefits:

• Quick and easy removal of the single-piece cartridge for cleaning or replacement
• Innovative diaphragm design for enhanced resistance against scale build-up
• Effective protection against over-pressurisation
• Multiple connection options for flexible installation
• Adjustable relief pressure range from 3.5 to 8 bar
• Designed exclusively for cold water applications

Specifications:

• Size: 3/4" x 22mm
• Connections: BSP Male Inlet x Compression Outlet
• Materials: Hot-pressed DZR Brass
• Medium: Cold water
• Set Pressure: 6 Barg
• Temperature: +140°C
