A Differential Pressure Valve(DP Valve) is a crucial component designed to control the pressure difference between two points within a system. Its primary functions are to maintain a constant differential pressure or to react to variations in this pressure. These versatile valves are employed in diverse applications, including heating systems, pumping systems, and even certain automotive brake systems.

DP Valve Key Concepts:

• Differential Pressure:
  The difference in pressure measured between two distinct points within a system.

• Control Function:
  The core function of a Differential Pressure Valve is to manage the differential pressure actively. This often involves maintaining a specific, desired pressure difference or responding to fluctuations to ensure system stability or performance.

• Differential Pressure Valve Applications:
  Differential Pressure Valves are utilized in various applications, наприклад:

  • Системи опалення: A Differential Pressure Valve for HVAC (often a type known as a DPCV – Differential Pressure Control Valve) is essential. It helps maintain a constant differential pressure across circuits or components in heating (and cooling) systems, ensuring even energy distribution, optimal system performance, and limiting excessive flow.

  • Pumping Systems: Differential Pressure Valves can maintain a constant pressure differential across a pump, safeguarding its operation and ensuring efficiency.

  • Brake Systems: In some dual-circuit automotive brake systems, a Differential Pressure Valve is used to detect significant pressure drops in one circuit, which can trigger a warning light.

  • Flow Metering: Differential Pressure Valves can be integral components in certain types of flow meters, where the differential pressure they help create or measure is used to calculate the flow rate.
