REXA delivers high-performance actuation, services, and consultancy enabling our customers to optimize their process performance and successfully manage safety, reliability, and environmental impact.
The process control needs within the oil and gas industry are diverse and ever changing. Upstream exploration occurs in harsh and remote environments where reliability and low power consumption are top concerns. Midstream transportation of these gases and liquids through continuously expanding pipelines is more complex than ever before. The wide range of pressures, flow rates, pipeline sizes, refined product properties and environmental regulations create significant challenges. Downstream refineries and petrochemical plants must maximize throughput while complying with strict safety and environmental regulations.
What is Hydraulic Actuation
Electraulic™ Actuation is a brand of electro-hydraulic actuation unique to REXA. It combines the simplicity of electric operation, the power of hydraulics, the reliability of solid state electronics, and the flexibility of user-configured control. The foundation of our technology is the patented breakthrough in hydraulic circuitry called the Flow Matching Valve System. In conjunction with a bi-directional gear pump coupled to either a DC stepper or AC servo motor, this system is a highly efficient method of moving hydraulic fluid from one side of a double-acting cylinder to the other.
Electraulic™ Actuation consists of two major components: the Actuator and the Electrical Control Enclosure. Each component plays a critical role in combining the benefits of major actuator types (pneumatic, electric, hydraulic) while eliminating the drawbacks of each technology.

About REXA
REXA delivers high-performance actuation, services, and consultancy enabling our customers to optimize their process performance and successfully manage safety, reliability, and environmental impact.
Being a responsible member of the communities in which we live and work is an important component of our mission. To support this commitment, we developed the REXA Cares program. This program encourages our employees to get involved in community improvement opportunities. All REXA employees are allotted 8 paid hours each year to put towards volunteering!
Additionally, REXA partners with various charitable organizations such as United Way of Greater Plymouth County. We also hold our own charitable fundraisers/donations each year that employees participate in. These include canned goods donations, clothing donations and sponsoring a family in need of assistance during the holiday season.
