Reliance RWC 101 Series Pressure Relief Valve 3/4" x 3/4" F x F 3 Bar - PREL101013

The PREL101016 Reliance Water Controls (RWC) 101 Series Sealed Heating System Pressure Relief Valve is designed to safely discharge water from the system at a predetermined pressure in the event of over-pressurisation. This robust valve is an essential safety feature, primarily utilised in sealed heating systems. Upon installation, the pressure relief valve is calibrated to the appropriate pressure setting. If the pressure within the system increases beyond this threshold, the valve activates, allowing excess pressure to be released into the atmosphere. This action safeguards the system from reaching hazardous pressure levels that could potentially cause damage or pose risks to individuals nearby.

Features and Benefits:

• Diaphragm design enhances resistance to scaling, significantly extending its lifespan.
• The single-piece cartridge allows for straightforward removal, facilitating easy access for cleaning or replacement.
• The adaptable relief pressure range of 2.0 bar to 6.0 bar offers flexibility for various system designs.
• Available with FSBP or MBSP/FBSP connections, providing complete installation versatility.
• Specifically designed for heating applications.

Specifications:

• Size: 1/2" x 1/2"
• Connections: BSP Male Inlet x BSP Female Outlet
• Materials: Hot pressed DZR Brass
• Medium: Water
• Set Pressure: 3 Barg
• Temperature Rating: +140°C
• Product Code: PREL101016

Introducing the PREL100015 High Capacity Sealed Heating System Pressure Relief Valve, designed to efficiently discharge water from the system at a predetermined pressure during instances of overpressure in heating systems, particularly in larger capacity setups. The Reliance Valves 100 Series Pressure Relief Valves are expertly crafted from hot-pressed brass, making them ideal for safeguarding closed-circuit wet heating systems from excessive pressure build-up. Featuring an outlet that is one size larger than the inlet, this valve ensures optimal discharge flow rates. The design includes a separate seal seating from the diaphragm, enhancing scaling resistance, while the cover is made from OT58 brass for additional durability. The PREL100015 is available in a range of sizes to accommodate most installations and has a pressure range of 2.5 - 5.0 bar, with the specified response pressure clearly indicated on the twist cap. The appropriate valve size is determined based on the heat output of the boiler, as outlined in the maximum heating capacity table.

Features and Benefits:

• Designed for high flow rates, perfect for larger capacity systems.
• Outlet significantly larger than the inlet for superior discharge capabilities.
• Provides essential protection against overpressurisation in wet heating systems.
• Improved diaphragm design offers enhanced resistance to scaling.
• Cartridge design allows for easy servicing and replacement without the need to reset the response pressure.
• Adjustable set pressure range from 2.5 - 5.0 bar to fit any system requirement.
• High lift design increases discharge capacity when needed.
• Suitable exclusively for heating applications.
