Superior Corrosion Resistance and Durability

Manufactured from high-grade A182 F5 alloy steel and reinforced with stainless or alloy steel trim, this piston type lift check valve offers excellent corrosion resistance and long service life. Its durable construction is ideal for handling aggressive fluids in challenging environments such as steam systems, oil refineries, and petrochemical plants.

Advanced Sealing and Pressure Handling

The valve features a metal-seated design conforming to leakage Class VI standards for reliable tight shut-off. With pressure classes up to 900 and the ability to withstand temperatures up to 600C, it is perfectly suited for high-pressure, high-temperature service conditions. The bolted bonnet structure also ensures secure and leak-proof operation.

Versatile Installation and Operation

Supporting both horizontal and vertical flow directions, this check valve accommodates a variety of piping layouts. Its straight shape and range of port sizes up to 24 inches provide unmatched flexibility in industrial setups. The flanged ends and compliance with ASME/ISO dimension standards ensure hassle-free integration into existing systems.

FAQ's of A182 F5 Alloy Steel Piston Type Lift Check Valve:

Q: How does the piston type lift check valve function in a pipeline?

A: This valve uses a piston mechanism that automatically opens when fluid flows in one direction and closes tightly when flow reverses, preventing backflow. The non-return feature ensures fluid moves only in the designated direction, safeguarding equipment and processes.

Q: What benefits does using an A182 F5 alloy steel body provide?

A: A182 F5 alloy steel offers superior corrosion resistance and high strength, making the valve ideal for harsh industrial environments. Its durability ensures reduced maintenance needs and extended service life, even under high-pressure and high-temperature conditions.

Q: Where can this valve be installed, and is it suitable for both horizontal and vertical applications?

A: This valve is designed for versatile installation in both horizontal and vertical piping systems. It's commonly used in industries such as oil & gas, steam, water, and petrochemical processing across a wide range of flow scenarios.

Q: What standards and testing processes does the valve adhere to?

A: The valve is designed and manufactured in compliance with ASME B16.34 and API 602 standards, with face-to-face dimensions to ASME B16.10. It undergoes rigorous pressure and leakage testing as per API 598, ensuring its reliability and performance in critical applications.

Q: When should a metal-seated lift check valve like this be selected over other types?

A: A metal-seated piston type lift check valve should be chosen when dealing with high-temperature or abrasive media where soft-seated valves might degrade. Its robust construction and tight shut-off make it preferable for processes requiring high integrity and durability.

Q: What is the recommended process for maintaining this check valve?

A: Routine inspection of sealing surfaces, bonnet bolts, and flow passage is advised. With its corrosion-resistant materials and bolted bonnet design, maintenance is straightforward, requiring only periodic checks to ensure leak-tight operation and longevity.

Q: What types of media can this valve handle effectively?

A: This check valve is engineered for compatibility with water, steam, oil, and various industrial fluids, thanks to its robust materials and tight shut-off feature. It's suitable for use in high-pressure and corrosive environments typical of many industrial and petrochemical processes.
