This workshop will teach you some process control fundamentals with instrumentation basics. You will also learn how to select and size control valves and avoid costly mistakes resulting in poor control.

Process Engineers and Instrumentation Technicians, as well as anyone working with or concerned about process control valve performance.

Day 1: Valves and Instruments in Process Control, Sizing

1. Introduction
   • Basics of instrumentation and control valves
2. Elements of Process Control
   • Role of control valves, ON/OFF vs. continuous control
   • Simple control strategies (flow, temperature, level), feedback vs. feedforward control
   • Common instrumentation and installation tips
3. Types and Selection of Valves
   • Valve selection tips, valve families, accuracy, turndown ratio, control accuracy
   • Using mid-range control, 3-way control valves
4. Theory of Valve Sizing
   • Theory origins, data on service conditions, calculating ΔP
   • Exercise 1: Sizing a valve with a pump and negligible pipe friction loss

Day 2: Sizing Complications, Gas Service, Actuators, and Common Valve Problems

5. Complications in Valve Sizing: Liquids
   • Friction losses, vaporization, choked flow, cavitation, flashing
   • Anti-cavitation measures, Exercise 2: Cavitation check
6. Control Valve Sizing for Gas Flow
   • CV for gas and steam, supersonic and choked flow
   • Exercise 3: Steam flow valve sizing
7. Noise in Control Valves
   • Noise in liquids, gas, and steam, anti-noise measures
8. Seals and Limits of Construction
   • Seals, packing, leakage rates, materials
9. Actuators and Actuator Sizing

• Safety, actuator types, air boosters
• Exercise 4: Actuator sizing

11. Diagnosing and Correcting Common Valve Problems

• Addressing valve non-linearity, stiction, hysteresis
• Positioners, cascade control
• Exercise 5: Diagnosing valve issues
