Common Operating Conditions

• Moderate Temperature — Chilled water (1-7°C), hot water (60-90°C)
• Low to Medium Pressure — PN6-PN16 typical
• Frequent Operation — Daily/seasonal modulation
• Space Constraints — Compact installation in mechanical rooms
• Energy Efficiency — Low pressure drop, precise control

Recommended Valve Types

• Butterfly Valves — Main riser isolation, compact and lightweight
• Gate Valves — Chiller and cooling tower isolation
• Globe Valves — Flow balancing and throttling
• Check Valves — Backflow prevention on pump discharge
• Strainers — Protect heat exchangers and control valves
