Niezgodka Type 70 SKM Reducing Valve Niezgodka Type 70 SKM Reducing Valve

The Altecnic / Caleffi 253 Solar Safety Valve - 253044 is essential for regulating pressure in the primary circuits of solar heating systems. This valve is specially selected based on the required set pressure. When the pressure exceeds the predefined limit, the valve opens and vents excess pressure to the atmosphere, effectively preventing excessive pressure that could harm solar collectors and other integral components within the system.

The Reliance Water Controls (RWC) TPR15 Pressure & Temperature Relief Valves are compact, yet highly effective, valves designed specifically to protect your unvented hot water system from the dangers of over-pressurisation. This critical safety feature is essential, as over-pressurisation can occur if the input temperature or pressure controls fail. The valves are strategically designed to be installed at the top of a hot water cylinder, where the highest temperatures are typically found. Should the temperature exceed 95°C, the wax mixture in the temperature probe's element will expand, lifting the valve from its seat and allowing excess water to be discharged safely. Additionally, if water pressure increases without a corresponding temperature rise, the valve remains closed until the pre-set pressure of the relief mechanism is reached, at which point it opens to relieve the excess pressure. Some models are equipped with a PTFE coating on the MBSP inlet thread, facilitating a quicker and more efficient installation process.

Features and Benefits:

• Protects against temperatures exceeding 95°C
• Prevents over-pressurisation in hot water systems
• Innovative twist-top cartridge design for straightforward servicing

Ensure the safety and reliability of your hot water system with the RWC TPR15 Pressure & Temperature Relief Valves, an essential component for maintaining optimal performance and peace of mind.

Refrigeration overflow valves equipped with a damping system are a specialised type of differential pressure control valve, specifically designed for use in industrial refrigeration systems. The integrated damping system enhances valve performance by stabilising operation and preventing pressure fluctuations or oscillations, particularly in systems that experience rapid changes in load or pressure conditions.
