CONCOA 445 Series Regulator

The Altecnic / Caleffi 527 Safety Valve - 527560EST is essential for effective pressure control in heating systems, particularly in heat generators, hot water storage units, and hydraulic systems. This safety valve is designed to open when the preset pressure is reached, discharging excess pressure into the atmosphere to ensure that the pressure in the system remains safely below dangerous levels for both the generator and the installed components. The 527 EST series valves are also fail-safe devices, ensuring reliability of operation even in the event of diaphragm wear or breakage.

NABIC 568 Anti-Vacuum Valves are essential for safeguarding drying cylinders, calorifiers, and tankers against collapse caused by internal vacuum conditions. These valves are equally valuable in steam systems, where they facilitate effective condensate drainage and prevent the unwanted suction of contents from vats. Typically, vacuum valves are installed vertically at the top of the vessel or pipeline they protect. In the case of horizontal revolving cylinders, a NABIC 568 valve should be fitted at each end, positioned directly opposite each other. Our NABIC Valves are backed by an industry-leading 5-Year Guarantee for your peace of mind.

Ensure the integrity of your systems with NABIC 568 Anti-Vacuum Valves—designed for durability and reliability in demanding applications.

The PREL103005 Sealed Pressure Relief Valve (PRV) with a 1/4" Gauge Port (valve supplied without gauge) effectively discharges water from the system at a predetermined pressure, in the event of over-pressurisation within your heating system. The Reliance Valves 103 Series Sealed Heating System Pressure Relief Valve is primarily designed as a critical safety component within sealed heating systems. Upon installation, the pressure relief valve is calibrated to an appropriate pressure. If the system pressure exceeds this set point, the valve activates and releases excess pressure into the atmosphere, thereby preventing the pressure from escalating to potentially hazardous levels that could not only damage the heating system but also pose risks to individuals nearby.

**Features and Benefits:**

• Diaphragm design enhances resistance to scaling, prolonging the valve's lifespan
• Easy removal of the single-piece cartridge allows for straightforward cleaning or cartridge replacement
• Set relief pressure range of 3.0 bar
• Available with 15mm connections for installation versatility
• Designed exclusively for heating applications

**Specification:**

• Size: 15mm x 15mm
• Connections: Compression Inlet x Compression Outlet
• Materials: Hot pressed DZR Brass
• Medium: Water
• Set Pressure: 3 Barg
• Temperature: +140°C
• Product Code: PREL103005
• Notes: WRAS approved, includes a 1/4" Gauge port (valve supplied without gauge)

Investing in the PREL103005 sealed PRV ensures the safety and integrity of your heating system, providing peace of mind and reliable operation.
