A thrust plate for a butterfly valve includes a thrust plate body that defines a recess. The recess extends between a bottom thrust surface, side walls and an open top. A wear-resistant coating is located on the bottom thrust surface.

A valve includes a flap, a tubular valve body defining a passageway, and a guiding device to guide the flap relative to the valve body for pivoting the flap relative to the valve body about a pivot axis between a closed position and an open position of the passageway. The guiding device comprises a pin traversed by the pivot axis and comprising a body with a base and, opposite the base, a free end resting against the valve body. The pin also comprises two lugs each protruding from the base in a direction opposite to the free end, the two lugs defining between them a slot, wherein an edge of the flap is received. The valve further comprises at least one member, connected to the flap, and which presses one of the lugs of the pin against the flap.

A valve comprises a flap, a tubular valve body defining an exhaust gas flow passage, and a device to guide the flap relative to the valve body to allow the flap to pivot relative to the valve body around a pivot axis between a closing position and a freed position of the exhaust gas flow passage. The flap has two large faces substantially parallel to one another and connected to one another by an edge of the flap. The guide device comprises a pin, a distal, end and a base. The valve also comprises a stabilizing member secured to the flap.

A valve includes a valve body having an exhaust gas inlet and an exhaust gas outlet, the valve body defining an exhaust gas circulation passage between the exhaust gas inlet and the exhaust gas outlet. A flap is arranged in the valve body and a shaft drives the flap in rotation with respect to the valve body. At least one guide bearing guides the drive shaft of the flap for rotation relative to the valve body. The guide bearing is engaged through an orifice of the valve body, with an inner end of the guide bearing being located inside the valve body. A first tube is engaged in one of the exhaust gas inlet and exhaust gas outlet and abuts against the inner end of the guide bearing.

An intermediate thrust plate is provided to absorb thrust loads while permitting rotation and deflection of a butterfly valve shaft. The intermediate thrust plate includes a body having upper and lower surfaces and defining an aperture extending through the body between the upper and lower surfaces, the upper surface extending annularly about the aperture and being substantially flat, the lower surface extending annularly about the aperture and having a spherical shape and at least the lower surface including a low-friction material.

The present invention relates to a tilting armature valve included at least a coil element having at least one coil core and a coil arranged radially around the coil core. The tilting armature valve may further include an armature mounted on a face side of the armature by means of a bearing. Furthermore, the tilting armature valve may include a sealing element arranged on the side of the armature facing the coil element or facing away therefrom. Moreover, the tilting armature valve may include a valve seat having an outlet and an inlet for a fluid, wherein the outlet is closable in a fluid-tight manner by way of the sealing element.
