Pressure Reducing Valve (PRV)

Water pressure is a key part of any plumbing system, but there is potential for too much of a good thing. The 535/536 Pressure Reducing Valve Kit is a problem solving assembly for applications where a single valve won’t cut it. Simplified, two-stage pressure reduction can save the day when high incoming water pressure puts extra stress on your system components.

For high-pressure plumbing systems, controlling water pressure is crucial to prevent damage and ensure reliable operation. When supply pressures exceed 200 psi, typically in high-rise buildings or systems with booster pumps, but also in water districts with high street pressures, a single Pressure Reducing Valve (PRV) may struggle to reduce pressure to a safe level. This can lead to issues like noisy and destructive cavitation, and ultimately damaging the other components all the way down to the faucet.

The 535/536 Pressure Reducing Valve Kit offers a solution with a two-stage pressure reduction system. The kit includes the Caleffi 536 PresCal HP piston-type PRV, perfect for the initial high-pressure stress and the 535 PresCal diaphragm-type PRV to dial in the perfect pressure at the taps.

This two-stage approach not only prevents cavitation but also extends the lifespan of the valves and other system components. It provides a reliable and efficient way to manage high-pressure scenarios, ensuring quiet and safe operation in even the most demanding plumbing environments. Whether dealing with inconsistent municipal supplies or high-rise booster systems, the 535/536 kit is a robust solution for maintaining optimal pressure levels.
