Pressure Control Valve
Pressure control valves are essential components in fire protection and industrial piping systems. They are mainly divided into two types:
Pressure Reducing Valve – Installed in series. It reduces high inlet pressure to a stable lower outlet pressure, protecting downstream equipment.
Pressure Relief Valve – Installed in parallel. It automatically opens when system pressure exceeds a preset limit, releasing excess water to prevent pipe or pump damage.
Both valves operate automatically without external power. They are widely used in fire pump rooms, high-rise building zone supplies, industrial plants, and oil depots.
Pressure control valves – making your system safer and more reliable.
