Special hydraulic valves

is a 3-way, 2- position high pressure diverter valve, designed for tipper-crane or truck&trailer applications in order to control 2 pressure lines separately.

Mechanical version also available.

• Pressure up to 400 bar
• Flow up to 250 l/min
• Open center scheme to prevent shocks while switching
• Cast iron body with anti-corrosion coating and nickel-plated spool
• Oil temperature: -25+80°
• Oil viscosity:12 ÷100 cSt

With cast iron body, this multifunctional hydraulic valve includes a maximum pressure valve, an anti-shock valve and an anti-cavitation valve.

With pneumatic or mechanical control, this valve is suitable for those applications with independent separate control of the cylinder (single acting) and the rear gate (double acting).

Different application configurations also available.

• Working pressure: up to maximum 315 bar
• Nominal flow rate: 140 l/min

The Binotto compensated flow control valve is the suitable solution for semi-trailer manufacturers.

Compact design, light, reliable and easy to install (flange for direct installation to the cylinder oil inlet also available). The Binotto compensated flow control valve operates to regulate the oil flow during lowering operation to maintain a steady speed . Binotto compensated flow control valve is the suitable solution for semi-trailer manufacturers.

In normal conditions (low flow rate), the valve will not operate or intervene to regulate the oil flow speed, it will just prevent overheating.

This safety valve only operates in critical cases (high flow rate conditions), whenever there’s a risk of the body lowering too fast, for example: if the hose connecting the tipping valve with the cylinder is damaged, burnt or broken or in the event of excessive load remaining on the body. In these critical cases, the Binotto compensated flow control valve regulates the flow during the lowering operation, preventing the cylinder from closing too fast and also preventing consequent hazards and risks. In these critical cases, Binotto compensated flow control valve regulates the flow during the lowering operation, avoiding the cylinder to close too fast and preventing consequent hazards and risks.

Available also for low temperature working conditions, upon request.

• Maximum pressure: 250 bar
• Aluminium manifold
• Nominal flow rate: 150 l/min

The maximum pressure safety valve is specifically dedicated to semitrailer application. During normal operations this valve works simply as an end-of-stroke device, just redirecting the oil flow to the oil tank at a very low pressure.

Whenever the pressure in the hydraulic system exceeds the preset safety pressure limit (such as in case of excessive load or in the event of failures of the end-of-stroke device, …), this valve works as a relief valve, limiting the pressure in the cylinder circuit at the preset valve pressure, discharging the oil to the tank with a very low hysteresis [less than 5%].
