MTRLOF
Mantern
High-rise fire systems are often subject to very high pressures at lower floors due to static head from tall water storage tanks or pumping arrangements. Without pressure reduction, these high pressures can damage hoses, equipment, or make firefighting operations unsafe. The PRLV ensures that water is delivered at a consistent and safe pressure—regardless of variations in the system—thereby enhancing operational reliability and safety.
These valves are usually installed at different floor levels in wet riser systems and are designed to comply with international standards such as BS 5041 and NFPA requirements. By integrating a pressure-reducing mechanism with a robust landing valve design, the PRLV combines safety, reliability, and ease of use, making it an indispensable part of modern firefighting infrastructure.
