Disclosed herein is a valve assembly for a feeding or drinking vessel. The valve assembly comprises a valve seat surface (229), and a valve element having a valve face opposing said valve seat surface (229), a center axis and a rim (232). The valve element further comprises a biasing element (242) configured such that, in a rest position, the valve face is biased against the valve seat surface (229), wherein the valve element rim (232) is arranged to be anchored and the biasing element (242) is arranged intermediate the valve element center axis and rim (232).

A valve includes an inlet unit including an inlet hole into which a fluid is introduced, a pressure adjusting unit which adjusts a pressure of the fluid introduced through the inlet unit, and a discharging unit having an opening and closing member which selectively discharges the fluid which had its pressure adjusted, and a water outlet hole which discharges the fluid passing through the opening and closing member to the outside, wherein a cross-sectional area of the inlet hole is greater than a cross-sectional area of the water outlet hole and a flow direction of a fluid from the pressure adjusting unit to the opening and closing member and a flow direction of a fluid from the opening and closing member to the water outlet hole are perpendicular to each other.

Automatic fluid control assemblies and methods for fire protection include an arrangement of electrically operated control points, a valve body and a controller to operate the fluid control assembly. The automatic fluid control assembly has an inlet, an outlet and a valve body to control flow between the inlet and the outlet. An electric latch includes a first electrically operated control point and a second electrically operated control point in fluid communication with a control line to control the flow of fluid from the inlet to the valve body and outlet. The methods of fluid control include controlling a plurality of electrically operated control points to perform any one of: a leak test, a trip test, a flow test, a water delivery test, and a validation test of a non-trip condition and a trip condition.

A method of diagnosing a valve is described, which has an electrodynamic actuator, which includes a magnet arrangement for generating a magnetic field and a control element which is movable relative to the magnet arrangement and is coupled to a movably arranged coil. At least one electrical variable of the electrodynamic actuator is measured over a measurement period to detect a time course of the electrical variable. The time course of the electrical variable is evaluated over an evaluation period to determine at least one induction-dependent valve variable which is assigned to the motion profile of the electrodynamic actuator. A diagnosis module and a valve are furthermore described.

A fluid control device (111) includes a valve section (12) and a blower section (13). The valve section (12) allows fluid to flow in one direction. The valve section (12) has the shape of a cylindrical container with a valve chamber (40) provided therein. The valve section (12) includes a top plate (21), a side-wall plate (22), a bottom plate (23), and a film (24). A plurality of ejection holes (41) and a plurality of auxiliary holes (49) arranged in a predetermined pattern are formed in a central region of the top plate (21). A plurality of communication holes (43) arranged in a predetermined pattern are formed in a central region of the bottom plate (23). A plurality of film holes (42) arranged in a predetermined pattern are formed in a central region of the film (24).

An intermediate piece for a stop valve, in particular a membrane valve, for fluids including a pressure piece. The pressure piece has at least two locking slides for locking a locking member of a closure element. The intermediate piece includes a cylinder in which the pressure piece can be guided in axial manner. The intermediate piece has a recess, which is arranged in such a way that in mounting position of the pressure piece the locking slide can be shifted into the recess, thus releasing the locking member.
