At Agritechnica, Hannover, Walvoil will showcase a number of innovative solutions for the mobile/agricultural sector, covering all product families: sectional valves and servos, pumps and motors, compact hydraulics and electronics.
Walvoil’s products and solutions meet the requirements of the most diverse applications: forestry cranes, harvesters, tractors and front loaders, telehandlers, seeders, ball-rollers, backhoe loaders, and many more.
The main applications of the products described in these pages are forestry machines and telehandlers: these applications require robust components and, at the same time, extremely precise control.
Walvoil is working to make the products of all families configurable.

Sectional valves feature a compact, light weight design
The DVS Series directional valves, Hydrocontrol branded, are a new family of sectional valves specifically designed for several applications: Forestry Machines, Skid Steer Loaders and Mini Dumper, Cranes, Wheel Loaders, Backhoe Loaders, Garbage Compactors, Hook and Skip Loaders, Drilling Rigs and Forklifts.
These valves have very exact control features, they are smooth and precise in operation, with compact light weight design. The DVS valves are also available in several configurations and custom solutions.
Working sections have auxiliary valves and a wide range of interchangeable spools.
The DVS valves can be fitted with integrated proportional electrohydraulic controls, and special configuration for LS variable displacement pumps is available on request.
Flexibility and simplicity of assembly are the main features of the whole range, that makes them suitable to satisfy different requirements and, above all, for retail market. Besides the DVS valves offer performance and energy saving capabilities.

The new hydraulic joystick is highly customizable
At Agritechnica Walvoil will launch the new SVM320 hydraulic joystick. It is an innovative, original, solid and reliable product particularly suitable for forestry applications and it is completely adaptable to customer’s needs by the modularity of the fixing flanges and the endless possibilities of configuration thanks to the compatibility with its whole range of products.
Thanks to its design, the new hydraulic joystick allows to manage and regulate flow rates with lower operating forces than the entire standard range may do.
The cast iron body ensures high durability, greater resistance to oil contamination and maintain unchanged features during the joystick life cycle.

Joystick for ISOBUS and safety-related applications
Thanks to an electronic department that is increasingly the protagonist of product and system proposals, Walvoil presents the new DJW joystick, that is designed for safety related applications up to Performance Level d / SIL 2.
Developed for telehandlers, this robust joystick is completely sealed and protected against water and dust ingress (IP67/IPx9K). The high-performance hardware architecture allows the joystick to be used in ISOBUS applications where a modern user interface (colour and high resolution) is required.
The DJW is suitable for 12V and 24V applications thanks to the 8 – 32V power supply input range.
With the high number of input pins, the joystick can collect all the signals of the handle (thumbwheels, push buttons, rocker switches and so on) and send them over the CANbus network with SAE J1939, CANopen, CANopen Safety or ISOBUS protocol.
The DJW protocol is qualified to meet the most rigorous international and customers’ standards.
