How to Size a Control Valve: Cv, Kv, Flow Cases and Valve Travel
Learn how to size a control valve using minimum, normal and maximum flow conditions, Cv or Kv, pressure drop, predicted valve travel and severe-service checks.
Control Valve Selection Guide: Body Style, Trim, Actuator and Severe Service
A practical control valve selection guide covering body styles, pressure-temperature ratings, trim construction, severe-service risks, leakage classes, actuators, accessories and project inspection requirements.
Single-Seated vs Double-Seated Control Valves: Which One is Right for Your System?
Compare single-seated and double-seated control valves by seat configuration, shutoff performance, pressure balancing, flow capacity, actuator requirements, maintenance, and application. Single-seated valves generally provide tighter shutoff and simpler maintenance, while double-seated valves handle higher flow rates and pressure differentials with lower actuator force.
