    Features & Benefits

    SB81 is a kind of groove signal butterfly valves are widely used in various industries for regulating and controlling the flow of liquids, gases, or slurries. Due to their efficient design and ease of installation. They are commonly found in the applications such as water treatment, HVAC systems and fire protection fields.

    The signal worm gear is part of the valve actuator, and its main function is to provide mechanical advantage to the valve operator. The worm gear reduces the input torque needed to turn the valve disc, enabling smooth and controlled operation. The gear mechanism ensures that even when the valve is under pressure, it can be easily opened or closed without requiring excessive force from the operator.

    The valve body of a groove signal butterfly valve is typically made from durable materials such as cast iron, stainless steel, or ductile iron, ensuring high resistance to corrosion and wear. The body is designed to have a compact, lightweight structure, which makes it easier to install and maintain. The grooved ends allow for easy connection to pipelines without the need for welding or threaded fittings, offering significant time and cost savings during installation.

    Groove signal butterfly valves typically feature a resilient, elastomeric seat material, such as EPDM, NBR, or Viton, which ensures excellent sealing performance. The design of the seat helps to create a tight seal around the valve disc, allowing the valve to shut off the flow completely when closed.
