Proper selection of pump control valves directly affects system efficiency and service life.
Factors including pipeline parameters, medium properties and environment must be considered.
First, match working conditions: confirm design flow, pressure and temperature to ensure size and rating fit.

  • For fluctuating industrial circulation, select valves with wide turndown ratio (above 100:1).

  • For hot water over 80℃, use high-temperature seals such as FKM to prevent leakage

Medium properties determine body material:

  • Tap water: cast iron / ductile iron

  • Sandy water / wastewater: wear-resistant cast steel with hardened trim

  • Corrosive media: 304 / 316 stainless steel

Easy installation and maintenance matters:

  • Vertical pipe: vertical valve; horizontal pipe: horizontal valve

  • Prefer removable bonnets for easy repair

  • Remote areas: smart valves with remote feedback to reduce on-site checks

Response time must meet system needs.
Fire systems require fast opening within 3 seconds.
