Valves are integral components in controlling the flow of gases and liquids in industrial systems. Over time, they are subjected to wear and tear due to exposure to harsh operating conditions, pressure, and corrosive environments. Regular inspection and testing of valves are essential to:

• Ensure Safety: Identify potential failures before they occur, reducing the risk of hazardous incidents and ensuring the safety of your workforce.
• Improve System Reliability: Well-maintained and tested valves reduce the chances of unexpected shutdowns, keeping your operations running smoothly.
• Extend Equipment Lifespan: Regular inspections help prolong the life of your valves by addressing issues before they lead to more severe damage.
• Maintain Compliance: Meet industry regulations and standards such as ASME, API, and other relevant codes, avoiding penalties and ensuring your systems are compliant.
• Optimize Performance: Ensuring that valves are functioning correctly improves the overall performance of your equipment, leading to greater efficiency and reduced energy costs.

At Zelwan Industrial Supplies, we offer a wide range of valve inspection and testing services to meet the needs of various industries. Our services include:

1. Visual Valve Inspection

A thorough visual inspection is the first step in assessing the overall condition of a valve. Our technicians check for visible signs of wear, corrosion, cracks, or any other defects that may affect performance. This inspection allows us to determine whether further testing or maintenance is required.

2. Hydrostatic Testing

We conduct hydrostatic testing to ensure that your valves can withstand the operational pressures they are subjected to. This involves filling the valve with water, pressurizing it beyond its operational limits, and inspecting it for leaks or failures. Hydrostatic testing is crucial for verifying the integrity of high-pressure valves used in industrial applications.

3. Pneumatic Testing

For valves that cannot be tested with water, we offer pneumatic testing, where compressed air or gas is used to test the valve’s sealing capabilities. This type of testing is particularly important for systems that operate with gases or in environments where water cannot be used.

4. Leak Testing

We provide leak detection testing to ensure that your valves are properly sealed and will not allow any unwanted fluid or gas to pass through. This test is essential for maintaining the efficiency and safety of systems where leaks could lead to operational losses or hazards.

5. Pressure Relief Valve Testing

We specialize in the testing and certification of pressure relief valves (PRVs). These valves are critical for ensuring safety in systems that operate under high pressure, as they release pressure when it exceeds a certain threshold. Our testing process ensures that your PRVs are functioning correctly, providing reliable protection for your equipment.

6. Valve Functionality Testing

Our team performs functionality tests to ensure that your valves are operating as intended. We check for proper opening and closing functions, as well as responsiveness to pressure changes, to guarantee that your valves are ready for use.

7. Custom Testing Solutions

We understand that different industries have unique requirements, and we offer custom valve testing solutions to meet your specific needs. Whether you have specialized valves or operate in extreme environments, we can tailor our services to provide the exact testing and certification your equipment requires.

At Zelwan Industrial Supplies, we follow internationally recognized standards for valve inspection and testing to ensure that your equipment is fully compliant with industry regulations. We adhere to the following standards:

• ASME (American Society of Mechanical Engineers) standards for pressure testing and valve performance.
• API (American Petroleum Institute) standards for valve testing in oil and gas applications.
• ISO 9001 for quality management in inspection and testing processes.
• ANSI Z540-3:2006 for calibration and test equipment accuracy.

By following these rigorous standards, we ensure that your valves meet all necessary safety and operational requirements, giving you peace of mind and confidence in your equipment.
