A system and method for maintaining the integrity of a dry pipe sprinkler system. The system can includes an auxiliary drain including a main collection pipe, a heater having a bracket configured to attach the heater to the main collection pipe of the auxiliary drain, the bracket including a deflector configured to direct heat from the heater onto the main collection pipe, and a self-draining apparatus configured to receive excess water from the auxiliary drain.

An explosion protection valve for decoupling system parts or workpieces, in particular for the installation in a pipeline, comprising a housing, a closing body which is axially guided inside the housing on a guide rod and can be displaced from a defined open position in the event of one of the group comprising a pressure and suction wave in the pipeline in at least one closing movement direction into a sealing closed position in which the closing body can be fixed by means of a locking device, a spring assembly, which is in operative connection to the closing body, on the guide rod for holding the closing body in the open position, bearing assemblies each carrying the end of the guide rod, which are each connected to the housing by means of at least one suspension cross-member, and a bearing arrangement, which is subject to play, of the at least one suspension cross-member in a receiving opening on the housing.

A downhole valve to be used in a flow management system that comprises a valve inlet for coupling with a hydrocarbon reservoir pump outlet, a valve outlet for coupling with production tubing transport to the surface pumped hydrocarbons, a valve body with a valve body centerline that extends between the valve inlet and outlet, and a spill port for bypassing a backflow.

A tire management system includes a control valve and a check valve. A method for managing a tire includes: determining a pressure parameter value, determining an operational parameter for a valve based on the pressure parameter value, and controlling the valve based on the operational parameter.
