Actuator maintenance

Maximum reliability. minimal downtime.

Actuators and control systems determine how reliably and safely a valve performs its function. Delta Controls specializes in the maintenance, overhaul and optimization of valve actuators and associated control systems, ensuring accurate operation under all operating conditions.

For more than 50 years, we have supported industrial installations with brand-independent actuator services — from simple pneumatic drives to complex hydraulic and electro-hydraulic systems. Our engineers combine workshop precision with practical field knowledge to deliver efficient execution and durable results.

Our actuator maintenance and overhaul services include

• Overhaul and refurbishment of pneumatic, hydraulic and electric actuators
