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.

**Features and Benefits:**

• The diaphragm design enhances resistance to scaling, thereby prolonging the lifespan of the valve.
• Easy removal of the single-piece cartridge allows convenient access for cleaning or replacing the cartridge.
• Flexible set relief pressure range from 2.0 bar to 6.0 bar aligns with diverse system design requirements.
• Available with FSBP or MBSP/FBSP connections, offering complete installation versatility.
• Designed exclusively for heating applications.

**Specifications:**

• Size: 3/4" x 3/4"
• Connections: BSP Female Inlet x BSP Female Outlet
• Materials: Hot pressed DZR Brass
• Medium: Water
• Set Pressure: 3 Barg
• Temperature: +140°C
• Product Code: PREL101013
• Notes: WRAS approved

This pressure relief valve is an essential component for ensuring the safety and efficiency of sealed heating systems. Invest in the PREL101013 Reliance Water Controls 101 Series for reliable performance and peace of mind.
