About Pressure Relief Valve

Pressure relief valve functions to regulate or restrict pressure spikes in pipes, protecting the system and guarding against instrument or equipment failure. It is employed in a variety of applications where high pressure is necessary for efficient operation, including petrochemical, oil and gas.

Pressure Relief Valve is a safety component that is commonly used in medium to high-pressure industrial flow systems to prevent damages in a case when pressure is elevated above the risk factor. It is designed as per industrial standards using top-quality materials. It is capable to bear a maximum pressure of 10 kilograms per square centimeter. Pressure Relief Valve offered by us is available in various sizes with a flange diameter between 165 to 445 millimeters.

FAQs of Pressure Relief Valve:

Q: How does the PRV-304 Pressure Relief Valve function in an industrial pipeline system?

A: The PRV-304 valve automatically releases excess pressure when system limits are exceeded, preventing equipment damage. Its spring-loaded mechanism opens the valve top discharge to efficiently vent air, water, gas, or steam before resetting automatically.

Q: What types of media can the PRV-304 safely handle?

A: This pressure relief valve is compatible with air, water, gases, and steam, making it suitable for pipelines, pressure vessels, and boilers used in various industrial processes.

Q: When should the PRV-304 Pressure Relief Valve be installed?

A: Install the PRV-304 during the setup or servicing of pressure equipment to ensure adherence to safety regulations and prevent accidental system overpressure events.

Q: Where is the valve ideally mounted for optimal performance?

A: The PRV-304 is designed for vertical mounting on pressure vessels, boilers, or pipeline sections with BSP threaded connections, ensuring effective top discharge operation and streamlined installation.

Q: What is the procedure for setting the desired pressure on the PRV-304?

A: The valve features an adjustable set pressure mechanism. During installation, calibrate it to the required pressure level (between 1 bar and 16 bar) using the test lever and spring adjustment to match system specifications.

Q: How does compliance with PED, ISO 4126, and ASME Section VIII benefit users?

A: These certifications indicate the valve meets rigorous international safety and quality standards, offering users confidence in reliable performance, legal compliance, and minimized risk in industrial operations.

Q: What are the advantages of the stainless steel build and PTFE sealing on this valve?

A: Stainless Steel 304 construction offers robust corrosion resistance and durability across a range of temperatures, while PTFE gaskets provide superior leak-proof sealing for reliable valve operation in demanding environments.
