Ship Bronze Flanged Check Valve CBM1077-81 for Pipeline Systems
A ship check valve, also known as a non-return valve, is an essential component within pipeline systems. Its primary purpose is to safeguard the system by preventing the backflow of the medium flowing through it. This crucial function helps to avoid the reverse rotation of pumps and their associated driving motors, as well as the unwanted discharge of the medium from containers. By ensuring one-way flow, check valves contribute significantly to the efficient and safe operation of various industrial and marine applications.
Marine Bronze Flanged Check Valve CBM1077-81: Detailed Specifications
- Design Standard: This marine bronze flanged check valve strictly adheres to the CBM1077-81 design standard, ensuring its reliability and compatibility with marine and industrial pipeline systems.
- End Standard: It follows the CBM1020 end standard, which guarantees proper connection and integration with other pipeline components.
- End Type: The valve features a flange end type, facilitating easy and secure installation and removal. Flanged connections are widely used in marine and industrial settings due to their strength and leak-proof capabilities.
- Nominal Pressure (PN): With a PN of 1.6Mpa, this check valve can withstand a significant amount of pressure, making it suitable for a variety of high-pressure applications in marine and industrial environments.
- Nominal Diameter (DN): The valve is available in a range of nominal diameters from 15mm to 40mm, providing flexibility to meet different pipeline size requirements.
- Main Material:
- Body/Bonnet: Made of BC6 bronze, which offers excellent corrosion resistance, especially in marine environments where exposure to saltwater is common. This ensures the longevity and durability of the valve.
- Seat: Also constructed from BC6 bronze, providing a reliable and leak-proof seal to prevent backflow.
- Disc: The disc is made of BC6 bronze as well, ensuring smooth operation and consistent performance.
- Application: This marine bronze flanged check valve is specifically designed for use in sea water, fresh water, oil, and steam piping systems. Its versatility makes it an ideal choice for a wide range of marine and industrial applications, including shipbuilding, offshore platforms, and power plants.
- Function: The primary function of this valve is to prevent refluence or backflow of the medium in the pipeline. By allowing fluid to flow in only one direction, it protects pumps, motors, and other equipment from damage caused by reverse flow.
