PRV-1A TYCO Pressure Reducer
TYCO Model PRV-1A Pressure Reducing Valves, from 2 to 8 inches (DN50 to DN200), are factory-assembled and fully equipped valve systems for pressure control. They are used on water-filled pipelines where it is necessary to reduce a higher inlet pressure to a lower outlet pressure under static and/or residual flow conditions.
The Model PRV-1A valve is designed to automatically maintain the outlet "set pressure" (static and residual) within a narrow range, regardless of fluctuations in higher inlet line pressure or changes in flow rate.
The Model PRV-1A valve is shipped with a factory outlet "set" pressure of approximately 125 psi (8.6 bar), but can be adjusted to a nominal outlet "set" pressure of 90 to 175 psi (6.2 to 12.1 bar).
Within a main manifold, as shown in Figure 1, feeding a wet pipe, dry pipe, deluge or pre-control system riser and/or a riser system feeding hose connections.
As part of a segmented floor control assembly, as shown in Figure 2, to supply sprinkler systems and/or hose stations.
