A way out valve for urinal with double little ball, characterized by being formed by two chambers, one lower and one upper, with small balls that move to let the liquids deposited in the urinal pass or seal and prevent the exit of gases of drainage; the upper chamber has truncated cone base that, when it has liquid, floats the ball that is in this chamber and allows the liquids to pass to the lower chamber; the lower chamber has an inclined roof that allows, on its upper face, to slide the liquids up to the vertical passage that transports the liquids to the lower chamber, passing them through the lower orifice; the lower chamber has a central perforation in its inclined floor where the liquids of this chamber pass to the liquid conduit towards the drainage.

A non-flushing urinal system with a large sealing and flow area using a bell-shaped valve with supporting ribs on its interior surface, which utilizes low crack pressure, or ease of initial opening to create for high flow rate and superior sealing.

A hybrid flushing system for water free urinals is presented with a housing having a wall portion forming a cavity for receiving a cartridge. The housing also includes a flushing fluid inlet portion for receiving a flushing fluid and a flushing fluid directing portion configured to direct the flushing fluid. A cartridge for installation into a housing is presented, including a cartridge wall, a flushing fluid receiving portion and a flushing fluid directing portion to direct flushing fluid received to any portion to clean areas of the housing, the cartridge, and connected plumbing. Steps for cleaning a hybrid flushing system are presented with an act of directing a flushing fluid into an area, where the area is one of a cartridge for a hybrid flushing system, a housing for a hybrid flushing system, and a plumbing system connected with the hybrid flushing system.

Described is a fluid control valve for use in a urinal having a drip edge to direct fluid flow. The fluid control valve includes an outer sealing body wall surrounding a sealing area and a flexible membrane positioned within the sealing area. The flexible membrane creates a seal with the outer sealing body wall within the sealing area. The drip edge of the fluid control valve may be formed in the flexible membrane or the outer sealing body wall to direct fluid away from the fluid control valve to prevent formation of solids build-up. Additionally, the drip edge can direct fluid towards a flushing sensor to initiate a urinal flushing operation.

The inventive subject matter provides apparatus, systems, and methods in which a valve mechanism is incorporated into a drain to reduce or prevent noise or food fragments from emitting out of an operating garbage disposal. The valve mechanism is generally a skirt valve biased to a closed position, disposed within a housing, and inserted into a drain such that food or fluid passes through the valve into a downstream grinding device. Once the food or fluid has passed through the valve, the valve closes.
