Single Pressure Dump Truck controls PT 1220 Valve / Tipping valves

The Hyva PT 1220 & 2220 tipping valves are constructed with a pilot operated pressure relief valve with fixed pressure setting (by means of cartridges), which protects both the cylinder and the pump for overpressure. This tipping valve is also designed to allow proportional lowering, which is of main importance when lowering (half) loaded bodies.

This tipping valve can be directly fitted to the Hyva oil tank, which reduces the number of hoses and fittings and consequently the possibility of leakages.

Additionally the Hyva PT 1220 & 2220 tipping valve is unique in the market as it has a peak pressure relief valve, to prevent serious damages in case of peak pressures.

The Hyva PT-valves & DHM valves can be mounted in line or directly on the oil tank. The PT-valve and the DHM-valve can be mounted on the same block. The PT-valves are controlled with a Hyva air control or manually. The DHM-valves are controlled by a cable control or by a Hyva air control.
