Within each hydraulic circuit of the pressure relief valves are the fundamental components to prevent damage from over-pressure due to shock or excessive loads. The valves of the series VMDR120 are pressure relief direct operated flow rate up to 120 lpm and pressures up to 350 bar. The run-parts-in-body, it can be installed in-line within the hydraulic system. The body and all external components are made of high-strength steel and subjected to zinc treatment to resist to the action of corrosive agents. The internal components are also made of steel, hardened and ground where necessary to ensure the correct level of performance to the valve.
These safety valves are used to guarantee the system not to exceed a given set pressure is exceeded would result in the likely cracks in the system. The operation is extremely simple, the valve is adjusted to a pressure slightly higher than that of job, if this value is exceeded by a malfunction of the system, the valve opens, dumping the oil in excess of the tank, the balance will be restored when the value of the pressure will drop below the calibration. The outer body is made of high-strength steel and externally protected from oxidation with a zinc treatment, it is possible to apply a surface treatment Zinc/Nickel to increase the resistance to oxidation, in the case where, for example, the valve is not very protected and exposed to the weather.
Within each hydraulic circuit of the pressure relief valves are the fundamental components to prevent damage from over-pressure due to shock or excessive loads. The valves of the series VMDR90 are pressure relief direct operated flow rate up to 90 lpm and pressures up to 350 bar. Running parts-in-body it can be installed in-line within the hydraulic system. The body and all external components are made of high-strength steel and subjected to zinc treatment to resist to the action of corrosive agents. The internal components are also made of steel, hardened and ground where necessary to ensure the correct level of performance to the valve.
