Product Selection Differences for Resilient Seated Butterfly Valves, Oil and Petrochemical

When selecting resilient seated butterfly valves for use in oil and petrochemical applications, there are several key differences to consider among the available options:

  1. Materials of Construction: Valves used in oil and petrochemical industries need to withstand harsh operating conditions, such as high temperatures and corrosive environments. Therefore, it is crucial to consider the material of construction. Options may include carbon steel, stainless steel, duplex stainless steel, or special alloys like Inconel or Hastelloy, depending on the specific application requirements.

  2. Valve Size and Pressure Class: The size and pressure class of the valve should be selected based on the flow rate, pressure, and temperature conditions of the application. Valves for oil and petrochemical applications often come in larger sizes and higher pressure ratings compared to valves used in other industries.

  3. Sealing Technology: Resilient seated butterfly valves use a resilient seat to provide a tight seal against the disc, which is critical to prevent leakage in oil and petrochemical applications. Different manufacturers may offer innovative seat designs and materials that enhance performance and durability in challenging environments.

  4. Compliance and Certifications: Valves used in oil and petrochemical industries must meet industry standards and regulations to ensure safe and reliable operation. Look for valves that meet standards such as API, ANSI, ASME, or ISO, and have relevant certifications like API 6D, API 609, or PED (Pressure Equipment Directive).

  5. Operational Features: Consider additional features such as actuation options (manual, electric, pneumatic, hydraulic), end connection types (wafer, lug, flanged), and any special requirements like fire-safe or fugitive emission standards compliance.

  6. Manufacturers and Reputation: It is crucial to select valves from reputable manufacturers with a proven track record in supplying reliable and high-quality products for oil and petrochemical applications. Consider factors like warranty, service and support, and references from other industry users.

By carefully considering these key differences among available options, you can select the most suitable resilient seated butterfly valve for your specific oil and petrochemical application requirements.
