    Features & Benefits

    SB71-V is a kind of UPVC (Unplasticized Polyvinyl Chloride) butterfly valve, which is commonly used in a variety of industrial and municipal applications, particularly in industries like water treatment, chemicals, irrigation, and HVAC systems. UPVC is known for its corrosion resistance, light weight, and cost-effectiveness, making it an ideal material for certain applications.

    These valves typically have a low operating torque, which makes them easier to operate and reduces the strain on the actuator and valve components. 

    The disc is engineered to resist corrosion and abrasion, particularly in chemical or water treatment applications, helping maintain valve integrity and longevity.

    The seat is usually made from soft elastomers such as EPDM (Ethylene Propylene Diene Monomer), NB (Natural Rubber), or Viton, which is commonly used for water or neutral liquids.

    The UPVC body is lightweight, making it easier to install and transport. It offers excellent mechanical strength for typical pressure ratings in water treatment, irrigation, and other low-pressure applications.
