Resideo Braukmann Z11S-A Automatic Reverse Rinsing Actuator

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

The FSKRDA rupture discs use advanced sector technology, ensuring the convex disc camber remains unchanged by operating pressure until reverse pressure is reached. Designed for high reliability, they handle up to 95% operating-to-burst pressure ratios and thousands of cycles without compromising performance. On activation, the disc opens fully along the scored line within milliseconds, without fragmentation. These discs are less sensitive to temperature variations, making them ideal for applications with wide thermal swings.

Their innovative design allows safe use with liquids only, including cycling and pulsating conditions, without reducing safety margins. They are particularly suitable for isolating safety valves. A wide range of materials and thicknesses provides excellent corrosion resistance, further enhanced with optional PTFE linings. Vacuum support is not required, and the discs can withstand high counter-pressures.
