Refrigeration suction filters are vital components within refrigeration systems, designed to safeguard compressors and other essential parts by removing contaminants from the refrigerant before it enters the compressor’s suction side. These filters effectively capture particles, oil, moisture, and other debris that could potentially harm sensitive components of the system, ensuring optimal performance and longevity.

Introducing the PREL102009 Reliance Water Controls (RWC) 102 Series Potable Water Pressure Relief Valve, expertly engineered to discharge water from the system at a predetermined pressure in the event of cold water over-pressurisation in an unvented cylinder. The Reliance 102 Series Potable Water Pressure Relief Valves serve a crucial role in safeguarding unvented systems from dangerous over-pressurisation. These valves are pre-set and locked at a specific pressure; should the system exceed this limit, the valve will lift off its seat, allowing water to be safely discharged to waste. Acting as the primary safety device in unvented systems, these pressure relief valves are constructed with a durable single-piece cartridge and are available in various pressure settings, ranging from 3.5 to 8 bar, along with multiple connection sizes to facilitate flexible installation.

Features and Benefits:

• Quick removal of the single-piece cartridge for easy cleaning or replacement
• Advanced diaphragm design enhances resistance to scale build-up
• Delivers robust protection against over-pressurisation
• Multiple connection options for adaptable installation
• Set relief pressure range from 3.5 to 8 bar
• Suitable for cold water applications only

Specifications:

• Size: 1/2" x 15mm
• Connections: BSP Male Inlet x Compression Outlet
• Materials: Hot pressed DZR Brass
• Medium: Cold water
• Set Pressure: 3.5 Barg
• Temperature: +140 °C
• Product Code: PREL102009

Invest in the reliability and safety of your unvented system with the PREL102009 Reliance Water Controls 102 Series Potable Water Pressure Relief Valve, designed for optimal performance and peace of mind.
