How do throttling blowdown valves work?
A throttling blowdown valve controls the removal of water from a boiler while regulating flow to maintain pressure and water level balance. The valve is designed for continuous or intermittent operation, gradually opening to avoid shock and excessive heat loss.
Advantages of throttling blowdown valves...
• Precise control of blowdown rate
• Reduces thermal shock to boiler
• Minimises heat and water loss
• Durable design for high‑temperature service
• Low maintenance in continuous operation
