    FAQs

    What is wafer check valve

    A wafer check valve, a vital component in the field of valve manufacturing, is a specialized type of check valve designed to prevent backflow in piping systems. Its name derives from its thin, wafer-like design, which allows for a compact and efficient structure.

    This unique configuration enables the wafer check valve to be sandwiched directly between two flanges within a pipeline. The valve opens to allow fluid to flow in one direction and promptly closes when the fluid attempts to reverse its course, thereby preventing backflow

    The wafer check valve’s disc mechanism is central to its operation. When fluid pressure increases on the upstream side, the disc lifts, permitting flow. Conversely, when the pressure decreases or reverses, the disc settles back into its seat, creating a seal that halts any backflow

    Notably, the wafer check valve is renowned for its minimal installation footprint, a result of its slim design. This makes it an ideal choice for systems where space is at a premium. Moreover, its lightweight construction reduces the need for extensive support structures, which translates into cost savings

    Application of wafer check valve in shipbuilding industry

    The application of wafer check valves in the shipbuilding industry is widespread and significant, given the sector’s unique requirements for space optimization, system reliability, and durable materials.

    Wafer check valves, with their compact design and efficient operation, are ideally suited for shipboard applications where space is at a premium. These valves can be fitted in extremely tight spaces, offering an optimal solution for the confined environments typically found on ships

    These valves play a crucial role in preventing backflow in various onboard systems. For instance, dual plate wafer type check valves with full rubber lining are commonly used in seawater desalination systems. The rubber lining provides added resistance to the corrosive effects of seawater, ensuring the valve’s longevity and consistent performance.

    What materials are wafer check valve made of?

    Wafer check valves are typically manufactured from a variety of materials, each chosen for their specific properties that lend themselves to certain applications and environments.

    1. Cast Iron: Cast iron is a common material used in the construction of wafer check valves due to its excellent durability and cost-effectiveness. It’s particularly suited for non-aggressive fluids at moderate temperatures

    2. Carbon Steel: Carbon steel offers excellent strength and durability, making it an ideal material for wafer check valves used in high-pressure or high-temperature applications.

    3. Stainless Steel: Stainless steel variants (304 & 316) are chosen for their corrosion resistance, making them well-suited for use in harsh environments or with aggressive fluids.

    4. Bronze:Bronze is another material commonly used in wafer check valves, especially for the valve disc component. This material provides good resistance to corrosion and wear.
