Abstract: This invention relates to an air valve which includes a deflector positioned inside a float chamber in order to improve the flow of air through the air valve. Further, the air valve includes an upper opening leading from the float chamber and having a transverse cross-section which increases away from the float chamber in order to smooth air flow. The invention further relates to an air valve accessory whereby an air valve can be modified in order to improve air flow therethrough.

Abstract: A tube extends through an attachment section and defines a vapor passageway. A housing is supported to the attachment section for movement between several positions relative to the attachment section. The housing defines a float chamber below the tube. A valve seat portion is located within the float chamber and has an engagement part, a sleeve part and a seat surface. The engagement part is connected to the housing. The sleeve part telescopically engages the tube and is movable along the tube with the housing. The valve seat portion defines a central bore open to the vapor passageway and the seat surface. The float moves within the float chamber. When to fluid enters the float chamber the float floats up against the seat surface closing off the central bore and the vapor passageway. In the absence of fluid the float moves downward exposing the seat surface.

Abstract: A ventilation valve (100) for ventilation of a tank (not shown) containing a liquid where the liquid surface fluctuates over time at the same time as the ventilation valve (100) obstructs external liquid to enter into the tank through the ventilation valve, is described. The ventilation valve (100) comprises a structural main housing (1, 2) containing a valve unit (3, 4, 5) and respective ventilation channels (6, 7, 9, 10, 13, 14, 16) providing open communication between the tank and the atmosphere, and the valve unit includes a movable float body (4) obstructing liquid ingress into the tank through said ventilation valve (100). The valve unit is in the form of a replaceable valve module which includes the float body (4) which is received in a valve housing (3). The structural main housing (1, 2) includes a socket part (2) and one from the socket part (2) releasable cover part (1) in order to provide access to the replaceable valve module (3, 4, 5).

Abstract: Auxiliary flow prevention mechanism for preventing leakage from the outlet of an air valve due to a seal malfunction of a primary stopper disposed in a primary conduit of a piping system. The mechanism includes an auxiliary conduit coupled downstream of the primary conduit. The mechanism further includes an auxiliary stopper housed within the auxiliary conduit. The auxiliary stopper is configured to seal an outlet of the auxiliary conduit when the primary stopper is in a sealing position but fails to prevent fluid outflow from an outlet of the primary conduit, whereby after sufficient fluid fills the air valve, the resultant increased fluid level urges the auxiliary stopper into a sealing position to seal an outlet of the auxiliary conduit, preventing fluid outflow therefrom. A visual indication of the seal malfunction is provided by a valve or pressure sensor that detects the presence of fluid in a downstream conduit section.
