WETKITS FOR TIPPING SEMITRAILERS
Optimal efficiency, low weight, short tipping cycle and safety are key principles followed while configuring wetkits for our customers. Our systems are fully optimized in terms of oil capacity, flow and working pressure to ensure the highest level of efficiency and safety.
A wide range of gear and piston pump sizes allows us to select a wetkit with highest performance for every type of truck, gearbox and PTO.
Hyva offers a complete range of oil tanks manufactured from highest quality steel and aluminium in several mounting positions on the truck frame or behind the cabin. The design ensures optimized shape and superior size to volume ratio to utilize as little space as possible, following the latest trends on modern trucks.
Hyva HT tipping valves are specially designed for tipping applications. They guarantee the highest standard of efficiency and safety. High flow rates reduce the tipping cycle, wear on the pump and extend the overall lifetime of the system. For over 15 years this unique design concept has proven to be the safest solution for tipping applications in all possible working conditions around the world.
Hyva tipping systems based on such components, and in combination with Hyva Alpha cylinders, are a fully harmonized and highly efficient solution, bringing its owner real savings at safe working conditions.

HYDRAULIC GEAR PUMPS
Hyva offers a wide range of hydraulic pumps for all offered wetkits and applications. Our most popular pumps are gear versions mounted on gearbox PTOs.
Gear pumps are mainly used for tipping applications on tractors or truck tippers. Due to highest quality of production and 250 bar working pressure standards these pumps are very durable even in the most demanding heavy duty applications.
The pumps are offered in several connection versions, the most popular are 3-hole and 4-hole mounting patterns (3H, 4H).
The great majority of Hyva pumps are bi-rotational. The rotation direction is determined by connection of the hoses without the need to disassemble the pump to change its rotation.
Hyva gear pumps are equipped with a unique safety system of leakage indicator to avoid internal leakages of oil from the hydraulic system to the gearbox and vice versa.

HYDRAULIC TIPPING V
HT 1220 SERIES
HT 1220 series valves are high performance valves suitable for the most demanding tipping applications with maximum oil flow of 220 L/min.
It is a very good choice for heavy duty and high speed tipping systems.
Hyva offers these valves in two mounting options, either on the tank mounting plate or directly on the Hyva cylinder SAE port.
If mounted directly on the cylinder it also acts as a hose burst valve in case of high pressure hose failure.
The maximum working pressure is secured by a fixed cartridge design, characteristic of Hyva HT valves. Its design guarantees the highest level of safety to avoid high pressure peaks during heavy duty operation.

OIL TANKS
Hyva offers a complete range of oil tanks manufactured from the highest quality materials – steel and aluminium. We offer several mounting possibilities – behind the cabin, on the side of the vehicle, in the cylinder cradle and others. All of our tanks are compatible with Hyva air breathers and return oil filters. Hyva HT 1150 and 1220 series tipping valves can be mounted either on mounting plates or directly on the return filter. The tanks are optimized for size, weight and working volume to deliver maximum efficiency in the hardest working conditions.

AIR CONTROLS
Hyva offers a wide range of configurations in air controls for tipping valves, PTOs and other related components with air pressure from 5 to 12 bar. Our options include spring return levers, fixed position options, automatic PTO disengagement and several others. Hyva air controls are proportional on lowering function for maximum precision and safety.

HIGH AND LO
HOSES
Hyva offers a full range of high pressure and low pressure (suction) hoses in several diameters, lengths and coupling types. Our pressure hoses are high quality, factory made products suitable to work with Hyva Alpha standards of 250 bar working pressure. Below our most popular items are presented.
