Custom valve blocks from Servi - custom made for marine, industry, mobile and offshore

Custom valve blocks

Our custom valve blocks combine the best of our own production with that of our manufacturers. We customise blocks to customer specifications for marine, industry, mobile and offshore. Together we determine the best system for your situation.

Ever since our establishment as Hydranor in 1962, we have delivered robust and reliable blocks to a wide range of sectors. Over the years we have become affiliated with partners of the highest calibre, including such suppliers as SUN Hydraulics, Eaton and HAWE. As a result, our production and expertise enables us to meet specific customer needs – from small blocks for use in a safe sawmill environment to a drilling rig far out at sea that is exposed to all the elements.

Combinable with most valves

Our custom blocks can be combined with most of the valves available in our range, such as from SUN hydraulics, Eaton and Argo Hytos.


Our valve blocks can also be adapted to a specific structure if desired.
The valve blocks have few physical limitations. Several types of fluids can be combined in the same block, such as environmental fluids, lubricants, hydraulic oil, compressed air, etc.

Advantages of our valve blocks:

Servi offers a safer and more environmentally friendly valve solution.
- Compact design: We use materials and a design that take up little space.
- Safer system: All pipe connectors have been removed from our valve blocks, thereby simplifying installation and preventing leakage.
- Fully tested prior to delivery: Servi pressure tests and supplies products in accordance with the documents and agreements made at the time of order.
- Consistent cost and quality: The installation method is the same every time and the test time of the hydraulic system is reduced to a minimum.
- Easy troubleshooting: The components are clearly marked, facilitating troubleshooting for the service technician.
- Maintenance-friendly: Few moving parts translates into little to no maintenance.


The combination of all these factors enables us to offer competitive prices.

Cartridge valves from SUN

Servi has been working closely together with SUN Hydraulics for several decades. SUN has set the standard in block-mounted valves, making their products the best available in today’s market. Our wide range of SUN valves – from big to small – are used in combination with Servi products. Standard elements are available in various models, with one that is suitable for every type of application.

Servi combines slides and cartridge valves.


With complex system constructions, it is essential that the oil is controlled accurately. Slide overlap often determines the extent to which a crane can move in a controlled manner. Our designers have many years of experience addressing such issues. It is precisely the combination of slide designs with an extensive range of cartridge valves that makes it possible to offer the most compact solutions.

 

Painting and testing

Painting and surface treatment to prevent rust

At our factory in Kongsberg, we carry out a wide range of surface treatments, including painting. Painting is important to enhance durability. The paint on the corners of hydraulic blocks tends to wear out quickly, so our blocks have rounded corners to prevent rust from forming. Two layers of component primer are applied before a top colour (of the customer’s choice) is added.

All of our blocks are 100% function and pressure tested in accordance with customer requirements.

Higher valve performance with digitisation (OPAT and HPRS)

Servi provides valve technology that ensures improved accuracy, repeatability, response and performance.
Servi’s range of SAC (Servi Addon Components) supplementary components consists of electronic units with BUS communication – ODC (Onboard Digital Controller) and OPAT (Onboard Profibus Atex Twinsolenoid) – that can be installed directly on the valves (OBE – On Board Electronics). The casings are solid and designed for use in harsh marine and offshore environments.


The SAC program includes an HPRS type (High Performance Range Sensor) sensor that is integrated into the valve. The HPRS contains an LVDT with extraordinary precision and 4-20 mA sensor signal.


Our customers are extremely satisfied with the OPAT and HPRS. Customer machines that already meet high standards of performance and precision double their performance in terms of speed and accuracy after such an upgrade. Also available with ATEX/IECEx certification.
