Double Offset Butterfly Valve Manufacturer in Mumbai, India

When compared to a concentric butterfly valve, a double-offset butterfly valve has two offsets.

We are leading Double Offset Butterfly Valve Manufacturer in Mumbai, India. The first offset is the shaft, which is not at the centre of the disc but slightly behind it. Because of this misalignment, the valve will have a continuous sealing surface on the disc.

The second offset is the shaft, which is not in the centre of the pipe but slightly to the right of it. When the valve is fully opened, this offset ensures that it does not come into contact with the seat (see illustration above). This configuration causes less friction in the seat than the concentric type butterfly valve, extending its life. In a typical application, this double-offset butterfly valve is only available in class 600.

  1. Higher Life Cycle
    The vulcanised liner's strength and strong connection with the body prevent it from being bent or torn by the disc during valve operations.
  2. Leak Free Tight Stem Sealing
    The flat surfaces on the top and bottom of the seal disc interface with similar profiles on the body liner, preventing leakage to the atmosphere due to the huge area of contact.
  3. ISO PAD Mounting
    The built-in ISO 5211 platform allows for direct installation of actuators and gear units, resulting in increased system dependability and efficiency.
  4. Minimum Flow Drop
    The discs have been developed hydrodynamically to give minimal flow resistance and increased flow coefficients.
  5. Easy Installation
    Between the valve and the companion flange, the valve's integrated liner works as a gasket. Unlike loose liner, the liner that is connected to the body is neither stretched or damaged during installation.
  6. Drive with Confidence
    A significant seal characteristic is the positive shaft-disc connection with anti-blow out. To reduce friction and enhance wear resistance, the shaft is Special-coated.

  • What is a butterfly valve?

    A butterfly valve is a type of quarter-turn valve that uses a disc or plate, known as a butterfly, to control the flow of fluid within a pipeline. The disc is positioned perpendicular to the flow in the closed position and rotates 90 degrees to allow full flow in the open position.

  • Are Butterfly Valves safe?

    Butterfly Valves are one of the safest valves to use. It works very well in high temperature and high-pressure services, making it safe for all types of use. At Freture, all our valves are manufactured as per international standards. Are 100% leak-proof and emission free. Saves down-time and process media. Maintenance free. Easy to install and remove.

  • How Do Butterfly Valves Work?

    When the disc is in the open position, it allows fluid to flow through the valve. When the disc is in the closed position, it blocks the flow of fluid. The disc is typically rotated by a handwheel or a pneumatic or electric actuator

  • What are the advantages of Butterfly Valves?

    There are three main types of butterfly valves:

    • Wafer butterfly valves: These valves have a wafer-like body that fits between two flanges, allowing them to be installed in pipelines without additional support.
    • Lug butterfly valves: Lug butterfly valves have threaded inserts on both sides of the valve body, enabling them to be bolted onto the pipeline.
    • Double-flanged butterfly valves: These valves have flanges on both ends of the body, allowing them to be connected directly between pipe flanges.
  • Can Butterfly Valves be used in both liquid and gas applications?

    Yes, Butterfly Valves can be used in both liquid and gas applications. The selection of materials and proper sizing of the valve should be based on the specific characteristics of the fluid or gas being controlled.

  • What maintenance is required for Butterfly valves?

    Regular maintenance for Butterfly Valves includes inspection, lubrication, and periodic testing of the valve components. This helps ensure proper functioning, prevent leakage, and extend the valve's lifespan. Maintenance requirements may vary based on the specific valve design, materials used, and the operating conditions.
