A venting and/or bleeding valve with a valve housing, a main valve arranged in the valve housing for rapid venting and bleeding of piping connected to the valve housing, an auxiliary valve arranged in the valve housing for operating ventilation of the piping at operating pressure, and a float arranged within the valve housing and controlling the main valve and the auxiliary valve as a function of the filling level of a fluid located in the valve housing. The venting and/or bleeding valve contains a valve position sensor for acquisition of the position of the main valve, at least one additional sensor for acquisition of the humidity and/or the pressure and/or of the temperature in an interior space of the valve housing, and an evaluation unit for acquisition of an operating state of the venting and/or bleeding valve as a function of the values acquired by the valve position sensor and any additional sensor.

A dishwasher includes a water jacket. The water jacket includes a water discharge path configured to discharge wash water to an outside of the dishwasher, a chamber in fluid communication with an upper end of the water discharge path, a check valve disposed inside the chamber, and a hinge disposed in the chamber and connected to the check valve. The check valve includes a floating portion with an empty inside. The specific gravity of the floating is smaller than that of water.

The double action float valve is connected to a single pipe and a tank and controls both the filling and discharge of the tank. The double action float valve utilizes a valve body, an obturator positioned within the valve body, a unidirectional device, and a float connected to the obturator. When the inflow pressure from the pipe is greater than the outflow pressure of the tank, the tank is filled until the float reaches a predetermined level. When the outflow pressure of the tank is greater than the inflow pressure, the double action float valve is automatically reconfigured to discharge the fluid from the tank into the pipe.

A delayed shutoff device comprises a conduit configured to allow a fluid to flow through, wherein the conduit includes a conduit start and a conduit end. The device further comprises a plug configured to be placed inside the conduit at the conduit start; move inside the conduit from the conduit start toward the conduit end when the fluid flows through the conduit; and reduce the fluid flow upon reaching the conduit end. The device is configured to allow a pass-through quantity of the fluid to pass through the conduit while the plug moves from the conduit start to the conduit end. The conduit end may form a seat, the plug being configured to stop moving upon reaching the seat. The plug may be configured to fit the seat imperfectly, to allow a seepage of the fluid after reaching the seat.

A leakage prevention module arranged to prevent fluid leakage from a tube connected apparatus arranged in the leakage prevention module, including a fluid tight trough including a drain in fluid connection with a drainage connection arranged to be connected to a drain tube, a wall with a recess where a lower end of the wall is fluid-tight fixed to the fluid tight trough such that the recess faces away from the drain. A first internal drain tube with a first end terminated in the recess and arranged to be connected to a drain tube from an apparatus and a second end in fluid connection with the drainage connection, a first feedthrough in the wall, a termination module arranged in the recess, where the termination module is arranged for terminating an inlet tube led in through the first feedthrough and further includes a first outlet arranged to be connected to a first supply tube to the apparatus.

An overfill prevention valve cooperative with a standpipe includes a plug, float, and seat that do not exceed the standpipe in diameter. The valve and standpipe can be inserted into a liquid holding tank from below. Rising liquid lifts the float and plug until the plug is sealed against the seat. The float can be above the seat and connected to the plug by a rod penetrating centrally through the seat. A check valve can enable draining of the holding tank when the liquid is withdrawn from the standpipe. The holding tank can be a fuel tank of a liquid fuel burning torch. A central reservoir system can automatically fill a plurality of holding tanks having the disclosed valves installed therein and connected in series by a plumbing system. Filling can be automatically terminated when a backpressure within the plumbing system exceeds a specified threshold.
