Knock-off valves

The pneumatic end-of-stroke valve for tippers is designed to stop the air flow to the main valve. This happens when the plunger is pressed against the cylinder by the rotation of the cylinder itself: this operation will stop the oil flow from the valve to the cylinder (resulting in direct oil discharge to the tank). In this way, it is possible to stop the cylinder extension once the desired stroke is reached.

The hydraulic end-of-stroke valves with a cast iron body, featuring a compact and robust design (up to 400 bar, flow rate up to 200 l/min), are mainly used for trailers and semi-trailers. They are used to interrupt the oil flow to the cylinder when the spool of the valve is pulled by a cable usually connected to the bottom of the tipping body. An alternative configuration with a plunger is also available.

In case of tipping vehicle equipped with a Binotto underbody cylinder, Binotto can also provide a special 3-way tipping end-of-stroke valve directly mounted into the cylinder cradle. When activated, the oil is diverted to the hydraulic tank. With flow up to 100 l/min and maximum pressure up to 300 bar, this solution is very strong and suitable for dump trucks whit limited space. No additional cables connected to the body are necessary.
