Product Selection Differences for Marine Resilient Seated Butterfly Valves

When selecting Marine Resilient Seated Butterfly Valves, there are several key differences to consider among available options:

  1. Material: The material of the valve body and disc can vary, with options such as ductile iron, stainless steel, or PVC. The choice of material should consider factors such as corrosion resistance, durability, and compatibility with the specific marine environment.

  2. Size and Pressure Rating: Marine Resilient Seated Butterfly Valves come in various sizes and pressure ratings. It is important to select a valve that meets the specific requirements of the marine system in terms of flow capacity and pressure rating.

  3. Sealing Technology: Resilient seated valves typically use elastomer seals for tight shut-off. Different types of elastomers such as EPDM, NBR, or Viton offer varying degrees of resistance to chemicals and temperature fluctuations. Consider the compatibility of the seal material with the fluids being handled.

  4. Actuation: Butterfly valves can be manually operated or automated with pneumatic or electric actuators. The choice of actuation method will depend on factors such as the frequency of operation, control requirements, and accessibility.

  5. End Connections: Marine butterfly valves come with different end connections such as lug, wafer, or flanged. The choice of end connections should align with the piping system and installation requirements.

  6. Compliance and Certifications: Ensure that the selected valve meets relevant industry standards and certifications, such as those from classification societies like DNV, ABS, or Lloyds, for marine applications.

  7. Manufacturer Reputation: Consider the reputation and track record of the valve manufacturer in providing reliable and high-quality marine valves. Look for manufacturers with a strong technical support system and a history of delivering durable products.

By carefully considering these factors, you can select the Marine Resilient Seated Butterfly Valves that best align with your marine system requirements in terms of performance, durability, and reliability.
