Hydraulic Valve Acutuators

Torque Control Hydraulic Actuators DA & SR series are based on Rack & Pinion Design. The Hydraulic Actuators are constructed with compact, simple and rugged design specifically for the Marine & Offshore industries.

The Double Acting Hydraulic Actuators (Series TCH-10DA to TCH-2000DA) are applicable for simple Open/Shut control to Intermediate Valve Position Control functions necessary for each valve control loop with wide operating Torque range from 100Nm to 20,000Nm.

The Single Acting Hydraulic Actuators (Series TCH-10SR to TCH-1000SR) are applicable fail safe operation which can operate with “Fail Close” function or with “Fail Open” function according to process requirement. Operating Torque range from 100Nm to 10000Nm.

There are various options and wide range of accessories that provides flexibility for any remote valve control system design and application requirement.

Hydraulic Actuator body materials range from Standard Carbon Steel to options for Stainless Steel 316 materials.

Standard Carbon Steel types are normally paint coated with tough Marine epoxy paint to withstand harsh and adverse Marine environment. Stainless Steel types are with high accuracy machining and good finish surface and material properties are resistant to Corrosions, Acids, Gases and Chemicals.
