Abstract
Abstract A regulator valve operative to open and close outlet ports in accordance with a differential pressure between the inlet and outlet conduits utilizing an actuator having O-rings fitted with O-ring grooves which O-ring grooves are slightly wider than the O-rings so that the O-rings will be compressed in the grooves by the inlet pressure to a depth equal to or less than the depth of the O-ring groove so as to prevent wear on the O-rings as they pass the openings during movement of the valve actuator. The movable valve actuator with its associated O-rings is additionally designed for different types of operations controlling more than one inlet port and more than one outlet port.
