Precision Engineering for Performance

Our Class 900 valves are manufactured to the highest industry standards including API 600, API 6D, and ASME B16.34, ensuring tight shutoff and superior leak prevention. With surface options like zinc coating or epoxy painting, and a choice of PTFE or graphite packing, these valves perform reliably across challenging environments and media.

Versatile Operation and Customization

Designed for user flexibility, these valves can be operated using a lever, gearbox, or automated actuators. Connection options encompass flanged, butt weld, socket weld, and threaded variants, conforming to ASME, DIN, JIS, and EN standards. Available in both full and reduced bore designs, they adapt to various flow and pressure conditions.

Comprehensive Application Coverage

These valves serve a broad range of industries, including petrochemical plants, power generation, and water treatment facilities. Supported by rigorous testing standards like API 598 and ISO 5208, they offer reliable sealing and optimal functionality whether handling water, oil, gas, or steam under extreme temperatures and pressures.

FAQ's of Class 900 Valve:

Q: How do I select the appropriate valve type for my application?

A: To choose the best valve type, consider your process requirements, media type, and operational needs. Ball valves are ideal for quick shutoff, gate valves for straight-line flow, globe valves for throttling, and check valves for preventing backflow. Consult with experts for guidance based on pressure, temperature, and media specifications.

Q: What materials are available for Class 900 valves and why is selection important?

A: Class 900 valves come in forged carbon steel, alloy steel, and stainless steel, conforming to ASTM A105, F304, F316, F11, and F22. Material selection affects durability, corrosion resistance, and suitability for different media, temperature, and pressure conditions. Please specify your requirements when ordering.

Q: When is it beneficial to use PTFE or metal seated valves?

A: PTFE seated valves provide excellent chemical resistance and lower friction, suitable for aggressive media or temperatures up to 425C. Metal seated valves are recommended for high temperature, abrasive, or steam applications due to their enhanced durability and longevity in harsh environments.

Q: Where can Class 900 valves be installed, and what are the typical applications?

A: Class 900 valves are commonly installed in petrochemical plants, refineries, power stations, and water treatment facilities. They are suited for controlling water, oil, gas, or steam flows in high-pressure and high-temperature scenarios, with flexible mounting via various end connection standards.

Q: What is the process for valve testing and quality assurance?

A: Every valve undergoes rigorous quality control in accordance with API 598 and ISO 5208 standards, including hydrostatic and pneumatic tests for pressure, sealing, and operational integrity. Certifications and test reports can be provided upon request to ensure compliance and reliability.

Q: How do the operational options (manual, electric, pneumatic) enhance usage?

A: The operational type-manual, electric, or pneumatic-facilitates integration into various systems. Electric and pneumatic actuators allow remote and automated operation, improving efficiency and safety, while manual operation suits less frequent control and budget-sensitive applications.

Q: What are the main benefits of using Class 900 valves from a certified manufacturer or supplier in India?

A: Sourcing from a certified Indian manufacturer guarantees adherence to global standards, reliable technical support, and prompt delivery. These valves are customizable to meet project-specific demands, ensuring efficiency, durability, and enhanced life cycle in critical industrial operations.
