AURA EXH Self-Relieving High Presure Regulator
The AURA EXH is a cutting-edge self-relieving high-pressure regulator specifically engineered for primary pressure control of non-corrosive gases and liquids, capable of managing delivery pressures of up to 4500 psig. When the delivery pressure is reduced, the EXH automatically vents excess downstream pressure to the atmosphere through the bonnet, ensuring consistent and reliable pressure control at all times. At its heart, the EXH features AURA’s innovative encapsulated seat design, which streamlines numerous moving components into a single assembly. This not only simplifies maintenance but also reduces potential failure points, thereby enhancing long-term reliability. The seat is safeguarded by a 10-micron, 360° filter that offers superior impurity filtration compared to traditional pressed-in disks. Unlike standard designs that only filter at the pipeline port, the EXH offers robust protection against harmful particles from all ports. With a variety of seat materials and orifice sizes available, the EXH guarantees optimal performance across diverse applications. Its high-load marginal spring ensures stable delivery pressures even at elevated flow rates, while its minimal installation requirements facilitate easy panel or surface mounting. In non-relieving mode, the EXH provides a positive shutoff with a helium leak-tight seal, ensuring maximum safety and efficiency. Each EXH is meticulously assembled and tested as a complete unit, incorporating any optional peripherals. Every regulator undergoes comprehensive flow and function testing to ensure durability, leak integrity, and consistent performance in demanding environments. Choose the AURA EXH for reliable pressure control that stands the test of time.

FSGGMG - Graphite Rupture Discs FSGGMG - Graphite Rupture Discs
The monoblock FSGGMG Graphite Rupture Discs are highly versatile and designed for a wide range of applications, easily positioned between flanges. These graphite rupture discs offer exceptional resistance to aggressive fluids and exhibit low sensitivity to temperature variations at varying bursting pressures. Manufactured from ultra-pure graphite and impregnated with phenolic resins, these discs ensure impermeability. Upon rupture, they provide a complete opening with fragmentation. For rupture pressures under 1.7 barg, vacuum support is required, while discs remain self-supporting at higher calibrations.

Altecnic / Caleffi 309 Series Pressure & Temperature Relief Valve 1/2" 90°C 7 Bar - 309473CST
The Altecnic / Caleffi 309 Pressure & Temperature Relief Valve - 309473CST is designed to effectively control and limit the temperature and pressure of hot water in domestic storage heaters. This essential safety device prevents water temperatures from exceeding 100°C, thereby eliminating the risk of steam formation. When the system reaches predetermined pressure or temperature thresholds, the valve discharges a sufficient amount of water into the atmosphere, ensuring that both temperature and pressure are maintained within safe operating limits. The valve's mechanism operates as follows: - **Temperature Control:** As the temperature in the storage heater rises, the thermostat compound within the temperature sensor, which is submerged in hot water, expands. This expansion causes a thrust pin to move, actuating the obturator and opening the valve. The valve is set to activate at temperatures exceeding 90°C. - **Pressure Control:** When pressure limits are reached, the obturator, which is opposed by a set spring, lifts and fully opens the outlet. The pressure setting is specifically configured according to the maximum allowable pressure within the system. As temperature and pressure subside, the valve automatically re-closes within designated tolerances.
