Product Detail

The SDNR (Straight Double Non-Return) feature of the Marine JIS F7353 5K Cast Iron Globe Valve enhances its functionality and versatility. The double-disc design allows for efficient flow regulation and ensures that the valve can prevent backflow in both directions. This makes it particularly suitable for applications where maintaining fluid flow direction and preventing reverse flow are critical, such as marine systems.

The straight-through flow pattern of the SDNR valve minimizes pressure loss and provides smooth flow characteristics. It enables the valve to handle high flow rates with minimal resistance, optimizing system performance and efficiency.

The Marine JIS F7353 5K Cast Iron Globe Valve is designed to meet the stringent requirements of marine applications. The cast iron construction ensures durability and corrosion resistance, making it suitable for use in challenging marine environments.

With its SDNR feature, this globe valve offers reliable and precise flow control, preventing unwanted backflow and maintaining the desired direction of fluid movement. It is commonly used in marine systems for various applications, including ballast systems, cooling systems, and fuel systems, among others.
