Valves selectoras: with bodies of smelting of high resistance
The valves called selectoras use at length in frontal and telescopic shovels, carts elevadoras etc. to instrument to the machine with additional functions. For example, a valve situated in the extreme of the telescopic arm of a loaders shovel can select between the functions of “inclination” and “pinzas”, using the same distributor (and an alone pair of flexible along the arm) by means of a pulsador electrical in the distributor that acts on the electromagnet of the valve.
They exist two main reasons that do attractor trucks this setting:
to) a valve selectora slope less than an element more in the distributor and b) only require a pair of flexible to act on two distinct services that find together but placed in a far extreme of the machine.
The range of valves selectoras Roquet is provista of bodies of smelting of high resistance produced in his own smelting and sliding carbonitruradas of high adjust to achieve a long life and low escapes. It devotes a special care to the design of the sliding and of the internal steps of the body to achieve an optimum relation of pressesure/discharge.
