Robust Design and Versatile ApplicationsThis pressure safety valve is engineered for optimum reliability and performance, making it an excellent choice for process piping across various industries. The corrosion-resistant construction, along with polished or natural surface finish, ensures long-term durability even under harsh operational conditions. Its vertical mounting and single-body structure make installation straightforward, while available caps (closed or open lever) allow for tailored usage.
High Accuracy and CompliancePrecision is central to this valve's design, offering set pressure ranges from 10 psi to 600 psi with high accuracy settings. The valves are thoroughly hydrostatic and seat leakage tested to comply with ASME and IS: 2825 standards, guaranteeing dependable operation and optimal safety for industrial processes. The spring-loaded adjustment allows fine-tuned control and consistent pressure relief.
Flexible Connection and Sealing OptionsSuited for a wide range of installation setups, the valve features BSP or NPT threaded/screwed or flanged connections. Users can choose between soft or metal-to-metal sealing, as well as PTFE or metallic seat materials to match their application's specific media, such as air, water, gas, or steam. The valve handles temperatures from -20C to 220C and comes in various sizes (1/2 inch to 2 inch).
FAQ's of Pressure Safety Valve:
Q: How does the pressure safety valve ensure equipment protection in industrial processes?
A: The valve automatically releases excess pressure using a spring-loaded mechanism, preventing possible damage or failure in piping and equipment. Its high-accuracy pressure setting and compliance with ASME/IS: 2825 standards ensure dependable operation in critical applications.
Q: What types of end connections and port sizes are available for these valves?
A: These valves can be supplied with BSP or NPT threaded connections, either screwed or flanged, and are available in port sizes ranging from 1/2 inch to 2 inches (DN15 to DN50), allowing ease of integration with various pipeline systems.
Q: When should the seat material be chosen as PTFE versus metal in these valves?
A: PTFE seats are ideal for applications requiring excellent chemical resistance and tight sealing, commonly used with corrosive media or where soft sealing is essential. Metal seats offer superior durability at higher temperatures and for more abrasive or high-pressure media.
Q: Where can these valves be installed in a process system?
A: These valves are recommended for vertical mounting on process piping or equipment that requires overpressure protection, whether in plants handling steam, gases, air, or liquids. Their design enables versatile use in industrial factories across sectors.
Q: What is the process for adjusting set pressure on this safety valve?
A: Users can adjust the set pressure via the external spring-loaded adjustment mechanism. This enables fast and accurate setting without disassembly, ensuring that the valve responds appropriately to the required pressure threshold.
Q: How does the valve guarantee leak-tight performance and safe operation?
A: Each valve undergoes rigorous hydrostatic and seat leakage testing to ensure it provides reliable shutoff and crew safety. Options for soft or metal-to-metal sealing and polished or natural finishes further enhance leak-tightness and compatibility with diverse media.
Q: What are the key operational benefits of using this pressure safety valve?
A: Key advantages include its robust corrosion-resistant construction, reliable high-accuracy pressure setting, compatibility with a wide range of media and temperatures, and compliance with international standards, making it a trusted choice for industrial overpressure protection.
