Disc Check Valves FMDCV

A flanged metal disc check valve is a type of check valve used to prevent backflow in pipelines. When fluid flows in the desired direction, the disc inside the valve lifts, allowing the fluid to pass through. When flow stops or reverses, the disc closes under its own weight or with the assistance of a spring, preventing backflow.

Disc Check Valves FMDCV

Feature

  • FMDCVs typically come with flanged ends, allowing for easy installation and connection to piping systems using bolts and nuts.
  • FMDCVs are constructed with durable metal materials such as carbon steel, stainless steel, ductile iron, or bronze, ensuring robustness and resistance to corrosion and erosion.
  • FMDCVs feature a swing disc design that allows for smooth operation and low pressure drop. The disc swings freely on a hinge or pivot to allow forward flow while preventing backflow.

    • Benefits

  • FMDCVs provide reliable backflow prevention by allowing fluid to flow in one direction while automatically closing to prevent reverse flow. This helps maintain system integrity and prevents contamination of fluids.
  • The design of FMDCVs typically results in low pressure drop across the valve, minimizing energy losses and optimizing system efficiency.
  • FMDCVs can be installed in a wide range of applications and industries, including water distribution, wastewater treatment, HVAC systems, industrial processes, and more. They are suitable for various fluid types and operating conditions.

    • Piston Valves PSVAL

    Piston valves regulate fluid flow by moving a piston or plug inside a cylindrical body to either block or permit flow through the valve.When the valve is open, the piston or plug is lifted or moved away from the valve seat, allowing fluid to flow through the passage.

    Piston Valves

    Feature

  • Piston valves offer precise control over fluid flow rates, making them suitable for applications where accurate regulation of flow is essential.
  • When closed, piston valves provide a tight seal against the valve seat, minimizing leakage and preventing backflow.
  • Piston valves are often designed to withstand high-pressure environments, making them suitable for applications with elevated pressure requirements.

    • Forbes Marshall Safety Relief Valve FMSRV

    The primary function of the FMSRV is to protect equipment and systems from overpressure situations by relieving excess pressure. The valve operates automatically in response to predetermined pressure levels. When the pressure inside the system exceeds the setpoint, the valve opens to discharge the excess pressure.

    FMSRV (DN 15) Forbes Marshall Safety Relief Valve

    1.FMSRV (DN 15) Forbes Marshall Safety Relief Valve

    The Forbes Marshall Safety Relief Valve (FMSRV) with a DN 15 designation refers to a specific model of safety relief valve manufactured by Forbes Marshall, with a nominal diameter (DN) of 15. The DN 15 designation indicates the nominal diameter of the valve, which is 15 millimeters. This size is suitable for applications where smaller flow rates or pipe sizes are involved.

    2. FMSRV (DN20-50) Forbes Marshall Safety Relief Valve

    The Forbes Marshall Safety Relief Valve (FMSRV) with a DN20-50 designation refers to a series of safety relief valves manufactured by Forbes Marshall, covering a range of nominal diameters from DN20 to DN50.The DN20-50 designation indicates that the FMSRV series covers a range of nominal diameters from DN20 to DN50. This range allows for flexibility in selecting the appropriate valve size based on the specific application requirements, flow rates, and pipe sizes.

    Feature

  • The primary function of the FMSRV is to relieve excess pressure from a system or equipment to prevent overpressure situations. When the pressure exceeds the setpoint, the valve opens to discharge the excess pressure, protecting the system from damage.
  • The valve operates automatically based on preset pressure levels. It opens when the pressure exceeds the setpoint and closes once the pressure returns to acceptable levels. This ensures continuous protection without the need for manual intervention.
  • Many FMSRV models allow for the adjustment of the setpoint to suit specific pressure requirements. This provides flexibility in application and allows for customization based on the needs of the system.

    • Benefits

  • The primary function of the FMSRV is to protect equipment, pipelines, and systems from overpressure situations by relieving excess pressure. This helps prevent catastrophic failures and ensures the safety of personnel and assets.
  • The valve operates automatically in response to predetermined pressure levels. When the pressure inside the system exceeds the setpoint, the valve opens to discharge the excess pressure, thereby preventing damage to the system.
  • FMSRVs are designed to relieve pressure rapidly and efficiently, minimizing the risk of equipment damage and ensuring the integrity of the system.
