Packaging options include wooden cases with a plastic layer, wooden pallets with a plastic layer, or steel crates, ensuring safe transportation and storage.

Key features of this cast iron wafer butterfly valve include its replaceable lining materials, bubble-tight sealing, ease of operation, long service life, and low maintenance requirements. With its multifunctionality and reliability, it serves as a dependable solution for flow control applications.

The Advantage Of Marine Cast Iron Wafer Butterfly Valve

The advantage of using a marine wafer butterfly valve made of cast iron lies in its specific characteristics and benefits. Here are some advantages of using a marine cast iron wafer butterfly valve:

• Strength and Durability: Cast iron is a strong and robust material, known for its excellent strength-to-weight ratio. It can withstand high pressures and temperatures, making it suitable for marine applications where durability is crucial.
• Thermal Stability: Cast iron has excellent thermal stability and can handle high-temperature fluids without losing its structural integrity. This property is beneficial in marine applications where the valve may be exposed to elevated temperatures.
• Noise Reduction: Cast iron valves can help reduce noise and vibration due to their inherent damping properties. This can be advantageous in marine systems where noise control is important for crew comfort or to meet regulatory requirements.
• Fire Resistance: Cast iron has high fire resistance, which is beneficial in marine applications where fire safety is crucial. The cast iron valve can withstand high temperatures and prevent the spread of fire, providing an additional layer of protection.

Ship Wafer VS Lug Butterfly Valve

When it comes to marine valves, two commonly used types are wafer and lug butterfly valves. Here’s a comparison of these valves in the context of marine applications:

• Design:
  • The wafer butterfly valve for marine applications has a compact and lightweight design. This marine valve is positioned between flanges and secured using bolts and nuts. They do not have additional flange holes or lugs.
  • The lug-type marine valves feature threaded inserts on both sides, allowing them to be bolted to the pipeline using separate flange sets. They have protruding lugs that provide additional structural support.
• Installation:
  • Installing a wafer valve in marine systems is relatively straightforward. It requires less space due to its compact design and are placed between flanges, which are then fastened using bolts and nuts.
  • For lug valves in marine applications, more space is needed due to the protruding lugs. These valves are attached to the pipeline by bolting them through the lug holes, providing enhanced stability and support.
• Pressure Rating:
  • Butterfly wafer valve typically has a lower pressure rating compared to lug valves in marine environments. As such, the wafer valve is suitable for applications with lower pressure requirements.
  • Lug-type marine valves are designed to handle higher pressure ratings, making them well-suited for marine applications that demand increased strength and durability.
• Maintenance and Repair:
  • Maintaining and repairing wafer valve in marine systems is generally easier due to its simpler design. It can be easily removed from the pipeline by detaching the bolts and nuts.
  • Lug valves may require more effort for maintenance and repair since they have additional flange sets and lugs. This means that the entire valve may need to be unbolted from the pipeline during servicing.
