Abstract: A control valve for adjusting the cross-sectional area of flow in at least one pipe, in particular for highly dynamic control of the coolant volume for cooling sections in rolling mills, includes a valve body, at least one valve seat and a positioning actuator configured for modifying the position of the valve body. The positioning actuator includes a linear electric motor in order to achieve reproducible response behavior, short response times and high positioning precision of the control valve.
Abstract: A limit switch assembly, for a rising-stem valve having a stem with a diameter and a groove marking a desired stem position, includes an actuator arm having an inner end and an outer end. The inner end of the actuator arm forms a follower. A radius washer is mounted to the outer end of the actuator arm. An electrical switch has an operating lever and is mounted adjacent to the outer end of the actuating arm such that when the actuator arm is in an outward position the radius washer moves the operating lever, operating the electrical switch. When the actuator arm is in an inward position the radius washer does not move the operating lever and the electrical switch is not operated. A bias spring biases the actuating arm toward the inward position.
Abstract: Sealing system of a device for allowing the passage of a medium, in particular in the high pressure range, is provided with a housing that has a bore hole, a component mounted within the housing such as to oscillate and/or rotate and with a pressure chamber formed within the bore hole. A sealing element surrounding the component adjoins this pressure chamber which can be charged with the medium. An additional metal seal is formed here by the housing and a pressure disc surrounding the component. The outer region is thus tightly closed after the sealing element. In this way, the sealing element is completely tightly encapsulated on the outside.
Abstract: A valve assembly for use in a fracturing pump including a valve member movable into and out of engagement with a valve seat body. The valve seat body includes an outer surface and an inner surface, the inner surface forming a fluid bore extending between a first end and a second end of the valve seat body. The body further includes a seating surface extending radially from the inner surface and facing the valve member, the seating surface having a recessed area. An insert is disposed in the recessed area forming at least a portion of the inner surface and at least portion of the seating surface. The valve seat body first end has a diameter different from a diameter valve seat body second. The difference between diameters allows the valve seat body outer surface to be supported by the fluid passageway.
Abstract: A pressure control valve is provided with a pressure control block. The pressure control block has a pressure control block having an opening portion provided on one outer surface, a pressure control surface provided as a plane at a bottom portion of the opening portion, and two internal channels having openings at the respective end portions of the pressure control surface. A sheet-like valve body having elasticity and arranged so as to cover the pressure control surface is provided in the opening portion of the pressure control block. A valve body driving portion is provided on a side opposite to the pressure control surface with the valve body interposed therebetween that adjusts an amount of a gap between the valve body and the pressure control surface by pressing the valve body in a direction perpendicular to the pressure control surface. The pressure control surface has higher hardness than a hard material.
Abstract: A fluid valve incorporates a plunger with a fluid channel. The plunger is connected to a boss coupled to a diaphragm, this boss also includes a fluid channel and the plunger and boss fluid channels are in fluid communication. The boss fluid channel opens to the backside of the diaphragm in the valve cavity and permits substantially complete pressurization or evacuation of the volume behind the diaphragm in the valve. The substantially complete pressurization of the volume behind the diaphragm enables full closure of the diaphragm and improves contact of the diaphragm with the valve seat thereby improving performance of the valve.

Abstract: An electromagnetic valve, in particular for a motor vehicle air spring system, has a valve closing body which, in its basic position, shuts off a valve outlet and, for this purpose, is pressed against a valve seat by a restoring spring. To assist the opening process, a valve spring is also provided. The valve spring is supported at one side on a valve seat body and at the other side on a spring pot, which is arranged on the valve closing body. Preferably, a tubular section of the spring pot bears, non-displaceably in a lateral direction, directly against the valve closing body. An elastic sealing element may either be arranged on the end side of the valve closing body, or held laterally by a section, which forms an enclosure, of the spring pot.
Abstract: A valve for use in a heating or cooling water circuit includes a housing that forms a feed line and a discharge line, and an adjusting unit that is formed separate from the housing and penetrates into the housing for adjusting a flow rate through the valve. The adjusting unit has a valve closing body which is operatively connected to a valve tappet in such a way that the valve closing body together with a valve seat body that in the intended operation is stationary in relation to the housing, forms a valve gap which is adjustable by axially moving the valve tappet. The valve is designed such that the valve gap in the intended operation, when the valve tappet is not actuated, is closed by closing forces and when the valve tappet is actuated in order to open the valve gap, these closing forces have to be overcome.
Abstract: A valve is provided having first and second flow channels connected by a passage. A sealing device is operable to open and close the passage to control fluid flow between the first and second flow channels. The sealing device includes a first sealing body and a second sealing body through which the passages extends. The first and second sealing bodies are biased together by a spring to close the passage. The first sealing body is passively movable by fluid and actively movable by an electromagnetic device to open the passage to permit fluid to flow between the first and second passages.
Abstract: An electropneumatic valve assembly comprises an electropneumatic pilot stage and a pneumatic power stage which is actuated by the pilot stage. Each pilot valve switches at least two power valves, and the valve assembly has a housing with an electrical signal input, with a compressed-air port, at least one vent port and at least one working outlet. The housing is layered with a pilot stage housing and a power stage housing connected along a substantially planar parting surface. At least one sealing element is between the pilot stage housing and power stage housing surrounding a control pressure region between the pilot stage housing and power stage housing. The control pressure region has two actuation regions for two power valves and has a duct-like connection with a defined flow cross section between the two actuation regions. An outlet of the associated pilot valve opens into the control pressure region.
