Niezgodka Type 30.1 Safety Valve - SG Iron - Lever 2

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.
