Valve Actuators, Electric Actuators and Mechanical Actuator Testing - Clark Testing

Valve Actuators, Electric Actuators and Mechanical Actuator Testing


Clark Testing has a long history of testing mechanical actuators and valve actuators for Nuclear, Petrochemical, Marine, Steel and other industrial applications. We test hydraulic, pneumatic, manual and Motor Operated Valves (MOV’s).

Clark’s has the capabilities to simulate the full complement of environmental conditions to accelerated life cycle aging of valve actuators and mechanical actuators. Testing is completed under Clark’s ISO 17025-2017 quality program.
