In this week's tip we will show you how to select the Lead Fill Valve on the Cougar Systems Elite Level Control Panel.
The 2019 Atlantic hurricane season has officially begun. The hurricane season, which includes the Caribbean Sea, Atlantic Ocean, and Gulf of Mexico, runs from June 1 to November 30. According to the National Weather Service, a hurricane is a tropical cyclone that has maximum sustained winds of 64 knots (74 mph) or higher. Hurricanes are also rated based on a scale of 1 to 5, with major hurricanes starting at a Category 3. The latter classifications are important to understanding how this year's hurricane season will impact both coastal and inland residents.
High-rise buildings present multiple challenges for water distribution due to the high pressures required to reach the top of the building. The high pressures in the lower levels of the building cause high-pressure drops across Pressure Reducing Valves (PRVs), over 100 PSI or more, creating the potential for cavitation within the valves.
Pressure Reducing Valve (PRV) Stations are an important component of a water-distribution system in a commercial building. The 2015 Uniform Plumbing Code Section 608.2 states that PRVs are required at any point where the system static pressure exceeds 80 PSI. Typically, this applies to mid- and high-rise buildings when the pressure boost required at the ground floor to serve the upper floors in the building is over 80 PSI. When designing a PRV Station, you must consider the station pressure drop, water flow, and safety devices.
