Additional Notes:

The PREL104002 Reliance Water Controls (RWC) 104 Series High Capacity Potable Water Pressure Relief Valve is designed to efficiently discharge excess water from the system when cold water over-pressurisation occurs in unvented cylinders. This high-flow valve is specifically engineered for larger capacity systems, ensuring superior performance and safety. The Reliance Valves 104 Series offers a robust solution for protecting unvented systems from over-pressurisation. Each valve is pre-set and securely locked to a specified pressure; should the system surpass this threshold, the valve will automatically lift, allowing water to discharge safely into the waste system. The outlet connection is designed to be one size larger than the inlet, ensuring that the valve can handle high-capacity discharges effectively. This valve serves as the primary safety device within an unvented system. Available in various pressure settings from 3.5 to 8 bar, as well as multiple connection sizes, it supports flexible installation options.

Features and Benefits:

• High-flow design ideal for larger capacity systems.
• Easy removal of the single-piece cartridge for cleaning or replacement.
• Innovative diaphragm design offers enhanced resistance to scale build-up.
• Effectively protects against over-pressurisation.
• Varied connection sizes for versatile installation.
• Set relief pressure range from 3.5 to 8.0 bar.
• Specifically designed for cold water applications only.
