Product Description
The Valve Pressure Limit Nefa 500kPa 15x15mm F PLV500FHS is a pressure relief valve designed for use in gas or fluid systems, specifically to regulate and control the pressure within a system to prevent over-pressurization. These valves are commonly used in residential, commercial, and industrial applications to ensure the system pressure remains within safe operating limits.
Key Features of the Valve Pressure Limit Nefa 500kPa 15x15mm F PLV500FHS:
-
Pressure Rating (500kPa):
- The 500kPa (kilopascal) rating indicates the maximum pressure at which the valve will open to relieve pressure. This means that if the pressure in the system exceeds 500 kPa, the valve will open and allow excess pressure to be vented, preventing potential damage to the system.
- It is commonly used in systems where the operating pressure is below 500 kPa, and the valve acts as a safety feature to protect components from over-pressurization.
-
Size (15x15mm):
- The 15x15mm size refers to the diameter of the valve connections, typically in millimeters (mm). This means the valve has 15mm threaded connections at both the inlet and outlet, allowing it to be installed in pipelines, hoses, or fittings with matching 15mm threads.
-
Material and Durability:
- The valve is typically made from corrosion-resistant materials such as brass, stainless steel, or other durable alloys. This ensures it can withstand the wear and tear of long-term use and exposure to the fluid or gas it is regulating, especially in high-pressure environments.
-
Type of Valve (Pressure Relief Valve):
- This is a pressure relief valve, designed to automatically open when the system pressure exceeds a set limit. The valve closes again once the pressure returns to safe levels, maintaining the system within the required operational pressure range.
- The valve works by using a spring-loaded mechanism, which is calibrated to open at a specific pressure (500 kPa in this case).
-
Female Threads (F):
- The "F" indicates that the valve has female threads for easy connection to male-threaded pipe fittings, making it adaptable for various types of installations.
-
Application in Gas and Fluid Systems:
- This valve is commonly used in gas pipelines, water systems, heating systems, or industrial fluid systems to prevent over-pressure conditions, which can lead to damage or even failure of system components.
Applications:
- Gas Systems: It can be used in gas appliances or gas pipelines to ensure safe pressure regulation. By preventing excessive pressure, it helps maintain the integrity of the gas system.
- Water Systems: In plumbing systems, particularly where pressurized water is used (e.g., heating or industrial systems), this valve ensures that the water pressure does not exceed safe levels.
- Heating Systems: Often used in hydronic heating systems, radiators, or boilers, where pressure control is critical to system safety.
- Industrial Applications: In pumps, compressors, or other industrial fluid systems, the valve can be used to control and maintain pressure within the equipment.
Symptoms Indicating the Need for Replacement:
- Constant Pressure Build-Up: If the system pressure is consistently rising above safe limits and the valve is not venting or relieving the excess pressure, the valve might be stuck or malfunctioning.
- Leaks or Visible Damage: If the valve shows visible signs of corrosion, cracks, or leaks, it may need to be replaced to maintain proper pressure regulation.
- System Malfunction: If the system is experiencing pressure fluctuations or failure to maintain constant pressure, it could be an issue with the valve, and it might need replacing.
