Overview
A welded manual butterfly valve is a quarter-turn flow control device featuring a disc that rotates within the pipeline. Constructed from carbon steel or stainless steel, it adheres to industrial welding standards for seamless integration into piping systems.
Application
- Petrochemical: Regulating corrosive fluids and gases in refinery lines.
- Water Treatment: Managing bulk water flow in filtration and distribution networks.
- Power Generation: Controlling cooling water circulation in thermal plants.
- HVAC: Isolating air handling units and hydronic circuits.
Precautions
- Safety: Ensure proper lockout/tagout procedures before maintenance to prevent accidental actuation.
- Maintenance: Inspect seals and bearings periodically; replace components immediately if leakage occurs.
- Installation: Verify weld alignment to avoid stress concentration on the valve body.
