Large Diameter Ventilation Butterfly Valve

Industries

• Water Treatment Plants: Used in water distribution and control systems for potable and wastewater treatment.
• Oil & Gas Industry: Suitable for regulating the flow of crude oil, natural gas, and refined products.
• Chemical Industry: Ideal for controlling the flow of chemicals, acids, and other aggressive fluids.
• HVAC Systems: Commonly used in heating, ventilation, and air conditioning systems for regulating air or water flow.
• Food & Beverage Industry: Suitable for sanitary and non-sanitary applications that require frequent operation and cleaning, thanks to corrosion-resistant materials and ease of cleaning.

Specific Applications

• Cooling Water Systems: Controls the flow of water for cooling applications in industrial facilities.
• Fire Protection Systems: Used in fire sprinkler systems as control valves to regulate water supply.
• Process Pipelines: Ideal for modulating or isolating flow in pipelines carrying oil, gas, or chemicals.
• Air Flow Regulation: Used in HVAC systems to regulate air flow, ensuring efficient operation of heating and cooling units.

Installation Instructions

• Verify the valve size, pressure rating, and material compatibility with the pipeline and medium before installation.
• Ensure proper alignment of the butterfly valve in the pipeline to avoid seat or disc damage.
• Use appropriate flange gaskets and follow standard torque tightening procedures for flanged connections.
• For wafer or lug connections, ensure correct bolt alignment to avoid stress on the valve body.
• Test the valve for proper operation to ensure the disc moves freely without obstruction. If the disc does not move freely, check for proper alignment and inspect for debris that may be causing the obstruction. If issues persist, further troubleshoot by adjusting alignment or cleaning the valve thoroughly to remove any contaminants.
