摘要： A siphon breaker includes a housing having a gas inlet and a gas outlet. The siphon breaker includes a stop valve adapted to transition from a closed position in which gas is substantially prevented from entering the gas inlet, and an open position in which gas is introduced into the gas inlet. The siphon breaker includes a control valve having a control valve gas inlet, a control valve gas outlet, and an electrically operated actuator. The control valve is adapted to transition from a closed position in which gas is substantially prevented from entering the control valve gas inlet, to an open position in which gas is through the control valve gas inlet.

摘要： A safety check unit for use in a liquid distribution system for preventing damage to a pump and associated components of the system in event of loss in pumping pressure. The unit provides a check component to prevent back-flow of the liquid when the pump is shut down, and provides protection against a possible vacuum condition in the system by introducing air to the system; protects against damage by a surging back-flow of liquid by opening a relief port of the unit; and protects against air in the system by use of an air relief mechanism of the unit.
