Patent number: 8839817Abstract: A valve with a dual rotational valve member is provided. The valve includes a first valve member and a second valve member. An actuation arrangement is operably positioned between the first valve member and the second valve member to rotate the first valve member in a first direction and the second valve member in a second direction opposite the first direction. This counter-rotation of the first and second valve members selectively aligns or misaligns a pair of flow ports of the first valve member with a pair of flow ports of the second valve member. When the pairs of flow ports are aligned, the flow path of the valve allows for straight through flow of a fluid through the valve thereby decreasing turbulence, back pressure, and noise.Type: GrantFiled: March 30, 2011Date of Patent: September 23, 2014Assignee: Schneider Electric Buildings, LLCInventors: Stanley S.

Patent number: 8807165Abstract: The invention relates to a control valve, in particular an angle control valve and double control valve, for extreme control applications, preferably for discharge or reduction for hot separators and vacuum distillation columns. The valve piston and the valve head are designed as one piece and consist of tungsten carbide. Furthermore, the control valve comprises different constructions across the entire control valve range. For example, the valve housing, the valve seat and a packing retainer are optionally shaped such that the inner hollow space tapers continuously from the valve inlet to the valve seat, which prevents evaporation upstream of the valve seat. Furthermore, the double control valve consists of a large sub-valve and at least one small sub-valve, wherein the large sub-valve is designed as an adjustable open-closed piston valve and the small sub-valve is designed as a control valve.Type: GrantFiled: June 6, 2011Date of Patent: August 19, 2014Assignee: Schuf Armaturen und Apparatebau GmbHInventor: Martin Frank

Patent number: 8783645Abstract: A variable flow rate valve system adjusts flow rate using the flow medium itself by creating differential pressures that determine a position of a valve member in relation to an associated valve seat. The valve system includes a diaphragm that divides a valve chamber into a control chamber and a flow chamber connected with an inlet. A valve body is connected with the diaphragm and cooperates with a valve seat to modulate flow from the inlet to an outlet and through the flow chamber. A first pilot valve in a first bypass extends between the outlet and the control chamber, and a second pilot valve in a second bypass extends between the inlet and the control chamber. The valves are controlled to selectively open or close respective bypasses to vary the flow through the flow chamber between a fully open and a fully closed condition in response to a control signal.Type: GrantFiled: October 20, 2009Date of Patent: July 22, 2014Assignee: Buerkert Werke GmbHInventors: Thomas Kirst, Stefan Müller, Kersten Grosse, Egon Hüfner
