Bolted body-cover design, seal welded & Valves with pressure seal cover
Bolted body-cover joints provided with spiral-wound stainless steel gasket and graphite filler for maximum protection against leaks
Die-formed graphite inner packing rings and braided graphite end rings with Inconel wire reinforcement and corrosion inhibitor
T-head stem-disc connection of gate valve fully meets strength requirements of API 602 and API 598
Rolled ACME thread on the stem for smooth operation
Tapered shoulder on the stem for back seating
Self-aligning type gland assembly with stud-and-nut tightening
Integral hard-faced body seat for globe and check valves
Spring-loaded disc on check valves suitable for no horizontal applications too
Gate and globe valves can be offered with electrical actuators
Austenitic SS forging for body and bonnet of Cryogenic valves, resulting in excellent impact strength, minimal heat loss, and resistance to corrosion
Valves can be offered to NACE MR-0175 and other special NACE requirements

Cast steel ASME B16.34 Swing Check Valves Pressure Seal Bonnet design

The ASME B16.34 Swing Check, and Y Type Swing Check Valves feature a pressure seal bonnet design for high-pressure services. These valves are extensively used in high pressure and high-temperature steam, oil, gas, chemical, and water applications in thermal power plants, fertilizer plants, petrochemical plants, and refineries. These valves are available in butt weld ends in pressure ratings of Classes 900, 1500 and 2500, and come in carbon steel and alloy steel construction.

Exceptional Durability and Corrosion Resistance

Manufactured from A351 CF3 cast stainless steel, this swing check valve is designed to withstand harsh industrial environments. Its corrosion-resistant properties make it suitable for continuous use with water, oil, gas, and a variety of chemicals, promoting longevity and reliability. The shot-blasted or pickled surface finish enhances its resistance to chemical attack, thus reducing maintenance frequency.

Versatile and Compliant Design

With adherence to international standards such as ASME B16.34, API 6D, and ANSI B16.10, this valve ensures compatibility with global pipeline systems. The flanged end connections and full port design permit unobstructed flow, catering to a diverse range of applications from DN50 to DN600 (2"-24"). Soft and metal seat options meet varied leakage class requirements, accommodating specific operational needs.

FAQ's of A351 CF3 Cast Stainless Steel Swing Check Valve:

Q: How does the A351 CF3 Swing Check Valve prevent backflow in pipelines?

A: This valve operates automatically; its swing design allows media to flow in one direction while the disc prevents reverse flow, ensuring non-return functionality in liquid and gas pipelines.

Q: What are the advantages of choosing A351 CF3 cast stainless steel for this valve?

A: A351 CF3 stainless steel offers excellent corrosion resistance and mechanical strength, making it suitable for demanding environments involving water, oil, gas, and aggressive chemicals, and promoting long-term durability.

Q: When should I select a soft seat versus a metal-to-metal seat for this valve?

A: Soft seats (like PTFE) are recommended when a high degree of sealing (Class VI leakage) is needed, especially for clean or low-abrasive media. Metal-to-metal seats (Class I leakage) are suited for higher temperatures or abrasive media where resilience is essential.

Q: Where is this swing check valve commonly installed?

A: It is typically used in industrial pipelines for water, oil, gas, and chemical transport, and is widely installed in facilities requiring reliable backflow prevention, such as factories, processing plants, and distribution networks.

Q: What standards and testing does this valve comply with?

A: The valve meets ASME B16.34, API 6D, and ANSI B16.10 standards, with pressure testing executed according to API 598. This assures users of its global compatibility and operational reliability.

Q: How does the bolted bonnet design benefit maintenance processes?

A: The bolted bonnet allows for easier disassembly, simplifying inspection and maintenance. It ensures a tight seal between the body and bonnet, reducing leakage risk and facilitating gasket replacement.

Q: What is the process for selecting the correct size and pressure rating for this swing check valve?

A: Determine your pipeline's diameter and pressure requirements, then select a valve within the DN50-DN600 (2 to 24 inch) size range and the desired pressure class (Class 150 or PN16) to ensure proper fit and reliable operation.
