A system for cleaning a dairy animal milker unit and applying dip to a dairy animal, the system includes a main control, an air supply, a water supply, a backflush fluid supply, a dip supply, a stall control for receiving the air, water, backflush fluid and dip supplies, and a safety valve that is adjacent to a downstream portion of the milker unit to control backflush and dip fluids being fed to the milker unit.

A fire protection sprinkler system and method of inerting a fire protection sprinkler system includes connecting an inerting system to the piping network of a fire protection sprinkler system having a piping network and at least one sprinkler head connected with the piping network. The inerting system includes an inert gas source that is adapted to supply inert gas to the piping network and an inerting gas vent assembly. The gas vent assembly has a gas vent adapted to discharge gas, a solenoid and a control. The solenoid is adapted to selectively open the gas vent and to close the gas vent. The gas vent discharges gas when the solenoid opens the gas vent and does not discharge gas when the solenoid closes the gas vent. The control is adapted to operate the solenoid in a manner that allows the gas vent to discharge gas for a limited amount of time.

A flushing tool for a perforated tubing in a production tubing string is described. The flushing tool includes a chamber that is sealed at a pressure at or below atmospheric pressure when the flushing tool is in its sealed configuration, the chamber arranged to receive wellbore fluids when the flushing tool is in its activated configuration. A port allows ingress of wellbore fluids into the chamber when the flushing tool is in its activated configuration. A sealing means has a first position when the flushing tool is in its sealed configuration and a second position when the flushing tool is in its activated configuration. An actuator releases the flushing tool from its sealed configuration to its activated configuration by releasing the sealing means to move from the first position to the second position.

A system for cleaning a dairy animal milker unit and applying dip to a dairy animal, the system includes a main control, an air supply, a water supply, a backflush fluid supply, a dip supply, a stall control for receiving the air, water, backflush fluid and dip supplies, and a safety valve that is adjacent to a downstream portion of the milker unit to control backflush and dip fluids being fed to the milker unit.

A pipe treatment system for a supply unit is provided. The pipe treatment system comprises a fresh water inlet pipe, a tap for fresh water, a controllable tap valve, and a control device for the pipe treatment control system. The controllable tap valve is arranged between the fresh water inlet pipe and the tap for fresh water. The control device for the pipe treatment control system is connected to the controllable tap valve so as to place the controllable tap valve in a pipe treatment state when there is a pipe treatment signal at the control device, so as to provide a more reliable pipe treatment system, for example for disinfection or descaling.

A hydraulic flushing system includes a hydraulic downhole control line that runs from a hydraulic source to a surface controlled sub-surface safety valve of an underwater hydrocarbon extraction facility, where the hydraulic downhole control line includes a directional control valve. The hydraulic flushing system further includes a purge line coupled to the hydraulic downhole control line downstream of the directional control valve to a service line. The purge line includes a fluid isolation valve therein to enable purging of a hydraulic fluid. The hydraulic flushing system further includes a service line coupled to the purge line via the fluid isolation valve to store the purged hydraulic fluid.

Described herein is a method and apparatus for providing an easy-flow flushing system to flushing out an engine and an out-drive. The easy-flow flushing system may include a cap with a tubular member, a capping member, and a sleeve. The tubular member may include a first outer surface, an inner surface, a coil circumscribing the tubular member to urge a sleeve to a closed configuration, an opening along the first outer surface, and a ball bearing seated in the opening. The capping member may be coupled to the tubular member and the capping member can include a capping member end and a sealing ring disposed along a second outer surface. The sleeve may be coupled to the tubular member. The sleeve may include an inner surface, where the sleeve is formed and shaped to slide along a portion of the first outer surface of the tubular member.
