Resideo Braukmann TKA295 Analogue BA RPZ Valve Testing Kit (Previously a Honeywell Product)

The PREL100023 High Capacity Sealed Heating System Pressure Relief Valve discharges water off the system at a set pressure in the event of system over pressurisation (high for larger capacity systems) Reliance Valves 100 Series Pressure Relief Valves are made from hot pressed brass and are predominantly used to protect closed-circuit wet heating systems from overpressure. The outlet is one size larger than the inlet to ensure high discharge flow rates. It has a separate seal seating from the diaphragm to give improved scaling resistance and a cover which is made from OT58 brass. Available in a variety of sizes to suit most installations, it also has a pressure range from 2.5 - 5.0 bar, with the response pressure indicated on the twist cap. The valve size is determined by the heat output of the boiler as shown in the maximum heating capacity table. 

Features and benefits: 

- High flow design for larger capacity systems 

- Outlet is one size larger than the inlet for high capacity discharge 

- Provides protection against over pressurisation in wet heating systems 

- Diaphragm design gives improved resistance against scale 

- Cartridge design gives ease of service and replacement without the need to reset the response pressure 

- Set pressure range from 2.5 - 5.0 bar to suit any system requirement 

- High lift design for increased discharge capacity 

- Suitable for heating applications only

The AURA EXS is a high-precision single-stage regulator designed for sub-atmospheric control and low-flow positive pressure applications. Its innovative hybrid spring system, paired with an oversized dual-surface diaphragm, allows for precise pressure regulation ranging from 0 psia to 100 psig, delivering exceptional accuracy in both vacuum and positive pressure scenarios. Central to the EXS is AURA's unique encapsulated seat design, which combines multiple moving parts into a single assembly. This groundbreaking design simplifies maintenance, reduces potential failure points, and ensures long-lasting reliability. The regulator features a 10-micron, 360° filter that offers superior impurity removal, far surpassing that of standard pressed-in discs. Unlike conventional regulators that only filter at the pipeline port, the EXS provides comprehensive protection across all inlet ports. Each EXS regulator is meticulously assembled in a Class 100 cleanroom as a complete unit, with all gauges, valves, and fittings pre-installed. The assembly undergoes thorough cleaning for oxygen service, is 100% helium leak tested, and is subjected to rigorous flow and functional testing to meet the most demanding application requirements. For particularly aggressive environments, the EXS can be equipped with Dursan® LS inert coating technology, which ensures exceptional resistance to acidic and caustic media, often outperforming more exotic alloys. Combining precise control, robust construction, and advanced corrosion resistance, the AURA EXS stands out as the perfect choice for engineers seeking reliable solutions for sub-atmospheric and low-flow applications.
