FOCUS ON: PIPES, VALVES & FITTINGS
COVER STORY
Caleffi PRVs in production.
A complete range for every requirement Series 533, 535 and 536 provide installers and specifiers with proven solutions for a wide range of domestic and commercial applications. By selecting the right valve for the system requirements, it is possible to improve performance, reduce wear on downstream components and support reliable long-term operation throughout the water system. “By selecting the right valve for the system requirements, it is possible to improve performance, reduce wear on downstream
Additional features include: • An internal strainer for debris protection • Low headloss characteristics to maintain flow performance • Quiet operation below 20 dB • Upstream pressure capability up to 25 bar These benefits make Series 536 particularly well suited to larger domestic properties, apartment buildings and commercial applications where performance, reliability and ease of maintenance are critical. Choosing the right PRV Selecting the correct pressure- reducing valve depends on the specific requirements of the installation. Series 533 provides a reliable and proven solution for domestic and light commercial systems where straightforward pressure control is required. Series 535 offers similar performance while adding pre-adjustment functionality to simplify commissioning. Meanwhile, Series 536 delivers advanced pressure management, enhanced serviceability and additional performance features for more demanding applications.
This simplifies commissioning and allows installers to achieve the required pressure setting more efficiently. Series 535 also incorporates a removable cartridge assembly, enabling periodic cleaning and maintenance without replacing the complete valve. Available in both standard and high- temperature versions, Series 535 is particularly suited to domestic hot water systems and installations requiring flexible pressure management. Series 536: Advanced pressure management Unlike Series 533 and 535, Series 536 uses a piston-operated design. Suitable for both hot- and cold-water systems in domestic and commercial buildings, it incorporates a compensated seat design that maintains stable downstream pressure regardless of fluctuations in upstream mains pressure. One of its key advantages is the extractable cartridge assembly, allowing internal components to be inspected, cleaned and maintained without removing the valve body from the pipework, significantly reducing servicing time and disruption.
