Broady AB Pressure Reducing Valve

The PREL101013 Reliance Water Controls (RWC) 101 Series Sealed Heating System Pressure Relief Valve is designed to safely discharge water from the system when a predetermined pressure is exceeded, providing essential protection against over-pressurisation in heating systems. The Reliance Valves 101 Series are widely utilised as a vital safety feature in sealed heating systems. Upon installation, the pressure relief valve is calibrated to the appropriate settings. When the system pressure elevates to this set limit, the valve activates, releasing water into the atmosphere to safeguard the system from reaching hazardous pressure levels that could potentially cause damage and present risks to individuals nearby.
