Abstract
Systems and methods described herein provide a pilot-operated oscillating valve including a diaphragm. The valve is configured such that when the diaphragm is in a closed position, pressure of a fluid supply opens the valve, and when the diaphragm is in an open position, the pressure of the fluid closes the valve. The oscillating valve may further include an actuator that can cause the valve to be arrested selectively in the open position or the closed position depending on a state of the actuator. The state of the actuator is switchable with a small expenditure of energy, enabling an extended duty cycle for a battery or other power source associated with the actuator. In some implementations, energy from the oscillating movement of the diaphragm may be captured to recharge the battery for the actuator.
