Industrial Positioners: Reliable precision for actuator and valve control
Positioners are a key part of industrial automation, enabling accurate control of actuators and valves to enhance efficiency and performance. Driven by a setpoint signal, an industrial positioner adjusts the valve or actuator to refine flow, pressure, and other critical process variables. Used in both demanding process environments and everyday applications, positioners increase control accuracy, helping reduce inefficiencies and minimise downtime.
This guide outlines the purpose, types, applications, and main advantages of SMC positioners, built to deliver high-performance actuator and valve control across a wide range of industries.
Positioner Types: Pneumatic and Electro-Pneumatic Options
To meet the diverse demands of modern industrial applications, SMC proposes this range of positioner types:
Pneumatic Positioners
- Use air pressure to control valve movement.
- Ideal in placees where compressed air is readily available.
- Durable, cost-effective, and reliable for many industrial applications.
- Examples: IP200 Series, IP5000/5100 Series
Electro-Pneumatic Positioners
- Use electrical signals to control actuator movement.
- Deliver precise, adaptable performance for advanced systems.
- Work with digital control platforms to enable higher levels of automation.
- Examples: IP8000 Series, IP8100 Series.
With features like feedback regulation and proportional–integral–derivative (PID) control built in, both options allow actuators to follow the setpoint with high accuracy.
Common applications for Industrial Positioners
Across many industries, positioners are mainly used to control valve opening and closing in automated systems, helping manage everything from flow to pressure.
SMC positioners are widely applied in the following industries and use cases:
- Oil & Gas – Helping manage flow and pressure in pipelines, drilling operations, and refinery processes.
- Chemical & Petrochemical Processing – Delivering stable, accurate control in reaction processes where precise valve positioning is essential.
- Power Generation – Managing steam and gas flow in turbines, boilers, and power plant valve control loops.
- Water Treatment – Managing valve operation in filtration, purification, and wastewater treatment systems.
- Pharmaceutical & Food Processing – Supporting accurate fluid control and material handling in pharmaceutical manufacturing and food production.
Built for demanding environments, SMC positioners deliver high reliability and robust control to support a wide range of industrial requirements.
