The tipping valve is the most critical component of the hydraulic tipping system as it directly influences the safety, performance and efficiency of the tipper. With this in mind, we have always paid a lot of attention to these components to deliver to the market the safest and the most efficient solution currently represented by the Hyva Type range of tipping valves.
Hyva Type tipping valve is a complete range of tipping valves to be used for different cylinder types and other applications driven by hydraulic systems. The HT 1220 is a single pressure series and the HT 2220 is a double pressure type. Both types can be used for oil flow up to 220 litres per minute and the pressure settings are from 110 to 350 bar.
Dual pressure valves (HT 2220) are used for applications where two working pressures are required, the pressure selection can be manual or pneumatic in the AS version.
For smaller flows, we offers the HT 1150 valve series. This valve is suitable for oil flow of 150 litres per minute and the working pressure settings available are from 135 to 250bar.
The complete range of Hyva Type tipping valves is based on the pilot operated pressure relief valve design with fixed pressure setting (by means of fixed value cartridges), which protects both the cylinder and the pump from overpressure. These pressure cartridges are fully interchangeable, so the pressure can be adjusted by its replacement in an easy and safe manner. The valve is also designed to allow
proportional lowering which is of great importance when lowering (half) loaded tipper bodies.
Hyva Type tipping valves (TNK version) can be mounted on the oil tank which reduces the number of hoses and fittings and consequently the posibility of leakages. The other version (SAE version) can be
mounted directly on the cylinder inlet port, in which case the valve also acts as a safety device in the event of a pressure feeding hose burst. The hose burst valve prevents the tipper body from falling in an uncontrolled way. Hyva type valves are pneumatically operated wit air controls optimised to ensure safe and precise operation of the system during its overall long lifetime.
