OEM Pneumatic Butterfly Valve Pricelist Factory

What are Pneumatic Butterfly Valve?

Pneumatic Butterfly Valve are used in pipelines to automatically vent air or gas from water mains as the line is filled or drained. They allow air pockets to escape while preventing liquid loss, protecting systems from the damaging effects of entrapped gasses.

Features of Pneumatic Butterfly Valve

• Body: Made from durable cast iron, steel or stainless steel to withstand system pressures.
• Float: Inside is a lightweight float attached to a linkage or mechanism that automatically opens/closes the Pneumatic Butterfly Valve.
• Seat: A resilient synthetic rubber seal creates a drip-tight barrier against water loss.
• Applications: Valves function for removing or releasing air in both filling (air valves) and draining (vacuum relief valves) applications.
• Operation: As water level rises in the pipe, air in the rising main escapes through the air valve by OEM Pneumatic Butterfly Valve Pricelist Factory. During drainage, pressure changes open vacuum valves to prevent collapse.

Applications of Pneumatic Butterfly Valve

• Water Treatment: Extensively utilized for flow regulation in municipal, industrial, and coastal desalination plants.
• Power Generation: Commonly found in the heating and cooling systems of power stations, refineries, and manufacturing facilities.
• Oil & Gas Industry: Frequently specified for pipelines in drilling rigs, refineries, and LNG/LPG terminals due to their bi-directional capability.
• Mining Sector: Employed in handling mineral slurries, sludge streams, and chemical flows within gold, copper, and coal extraction processes.
• Chemical Applications: The availability of elastomer seat options and suitable body materials make Pneumatic Butterfly Valve a top choice for the chemical, food, and plastics industries.
• Maritime Usage: Specially coated valves exhibit resilience to seawater intake and are perfect for ballast and bilge applications on ships, offshore rigs, and remote platforms.
