Abstract
A maximum pressure selector device in which a valve ball is pressure actuatable in a chamber intermediate two cooperating valve seats of opposing input chambers. Positioned between the seats is a pair of orifices which connect the intermediate chamber to an output port. The orifices are of a predetermined size for allowing a predetermined maximum fluid flow rate therethrough for reducing surge flow. The valve ball is positioned in an encircling sealing arrangement centrally located in the intermediate chamber and is restricted to limited movement therein. The input chambers communicate with the intermediate chamber and thus with the output port, depending on the seating position of the valving element.
