Denley Hydraulics - Electro-Hydraulic Engineering Systems, Products and Services

Denley has, over the last half a century, developed an internationally recognised reputation in the international offshore oil and gas industry for the delivery of safe, reliable and cost-effective electro-hydraulic engineering systems, products and services. Our electro-hydraulic engineering systems, products and services are highly imaginative, individually tailored and often ground-breaking.

Electro-hydraulic power systems, high-pressure instrumentation panels and manifold block options and valves

Denley’s global expertise in the oil and gas industry covers not only large, centralised electro-hydraulic power systems, but also their associated and often extremely complex, high-pressure control and instrumentation panels, complete with a wide range of standard, custom-built and special-purpose manifold block options and valves.

Denley is a BSI-registered firm (certificate number FM 20943), whose quality management system controls all its design, manufacturing and installation operations, in full compliance with ISO 9001:2008.

Single and double-acting heavy duty hydraulic cylinders

The company’s innovative design and engineering capabilities also provide a technologically advanced hydraulic cylinder and actuator (both top-side and sub-sea) design, testing and manufacturing facility, including the delivery of many standard, but more often project-specific, single and double-acting heavy duty cylinders.

Denley’s comprehensive range of core competencies is not only the foundation upon which the company has built a technically strong and strategically complete customer services capability and expertise in the oil and gas business over the years, but more importantly, it is the basis upon which customers have grown to trust and rely on the Denley brand to deliver imaginative, operationally practical and safe electro-hydraulic engineering solutions.

Electro-hydraulic system quality control, design, testing and manufacturing

Many of the highly bespoke products designed and manufactured for the international oil and gas industry by Denley are not only safety-critical and subject to dramatic extremes in temperature, but also open to some of the harshest elements on earth.

Here equipment performance and reliability, including the material’s ultimate specification and resistance to such harsh, hazardous, corrosive and environmentally challenging environments, are always at the forefront of Denley’s quality control, design, testing and manufacturing protocols.

Rig machinery, tooling, actuator and control and instrumentation equipment

Specific to the offshore oil and gas industry, Denley’s market knowledge and imaginative engineering skills not only fully extend to a rig’s general range of operational equipment, but also the rig’s more highly specialist operational machinery, tooling, actuator, and control and instrumentation equipment, including that of its sub-sea controls and equipment.
