A Flexible valve wrench to operate your manual valves

The Sofis Power Wrench is highly flexible, easy-to-mount, and perfect for turnarounds and other valve maintenance activities. It can be quickly attached to any valve due to its adaptable design. This portable actuator is completely portable. With its universal drive plates, the valve wrench can be mounted and remounted wherever required. There is no manufacturer installation necessary. Operation of the portable actuator is easy and safe within the recommended boundaries. You are in control about the applied force and speed. Various safety aspects protect you during the setup and operation.

Prevent operator injuries

Repetitive actions subject the body to stress. Operators responsible for maintenance in large utility or refinery plants are at risk of occupational health issues, such as muscular or skeletal illnesses from repetitive strain injury (RSI) or over-exertion. They are also more prone to workplace accidents if proper procedures are not followed. A specific challenge for operators is the frequent manual operation of valves. Manually rotating these valves involves highly repetitive motions, repeatedly straining the same muscles and body parts. Additionally, remaining in the same position for extended periods causes fatigue, adding to the risk. With a Sofis portable actuator, you avoid operator injuries caused by strain or over-exertion during manual valve operations.

Actuate any valve thanks to flexible mounting

You can use the open end Power Wrench for any type of valve. Preparing the valve only takes minutes. You quickly bolt a universal drive plate onto the hand wheel. Then connect the tool to your plant air system and you are ready for operation.

Ensure smooth and reliable manual valve operations

Efficient and rapid operation of manual valves is crucial for maintaining a safe working environment and reducing the risk of interruptions or shutdowns. Sofis portable valve actuators and valve openers provide versatile solutions tailored to various operational needs. These portable valve actuators ensure smooth and reliable valve operation, enhancing overall productivity and safety.

What our customers say

The Power Wrench manual valve actuator is a great device for us, because we can open and close our manually operated valves much more quickly and safely. The tool is a safe device, for it can only be operated with both hands. It allows me to do my job faster and more easily – which is great because I’m not getting any younger.- G. Knepper, Dayshift Operator, HDPE Polymers – Production, SABIC Europe B.V.
Previously, our valves were being opened and closed manually by our operators. This resulted in injuries such as stiff, sore and strained backs, shoulders and arms. Using the Power Wrench manual valve actuator, these injuries are now no longer an issue.- J. Habets, Senior Dayshift Operator, HDPE Polymers – Production, SABIC Europe B.V
