Pack Part of malleable material which seals the passage of the actuator by the pressure-bearing housing. Packing room Space in the pressurized housing that houses the pack. PEEK (PloyEtherEtherKeton) PEEK is a high performance material with exceptional thermal mechanical and chemical properties. Can be used up to approx. 250 ° C - temporarily up to 300 ° C. At room temperature, PEEK can be thought of as aluminum. For example, a PEEK sealing cup that falls on a tabletop sounds something like aluminum. The area where PEEK begins to become supple and provides some flexibility begins at about 60! C. QA module The QA modules describe the type and scope of the tasks to be performed by the manufacturer and / or the notified body. These are modules for processing in connection with an object inspection by the manufacturer or by the notified body (modules A, A1, B, B1, C1, F and G) or modules for processing in connection with an approved and supervised quality assurance system (Modules D, D1, E, E1, H and H1). Quality Management Quality Management (QA Management) is the method that a company applies to meet quality requirements. Control range The control range Xh of a control is the range within which the controlled variable can be set taking into account agreed values of the disturbance variables without the agreed maximum setpoint deviation being exceeded. NOTE: If the control range Xh so determined is not at the same time the intended input range of the controlled variable in the control device, the control range defined on the controlled system is designated XhS and the control device XhR. Rules The rule is a process in which one variable, the controlled variable (the variable to be controlled), is sequentially detected, with another variable affecting the leader size. Characteristic for the rules is the closed course of action, in which the controlled variable in the path of action of the control loop continuously influences itself. NOTE: The process of control is considered to be continuous even if it consists of a sufficiently frequent repetition of similar individual operations (eg two-point links). The designation regulation is often used not only for the process of the rules, but also for the entire system in which the regulation takes place. The resulting effect sequence takes place in a circle, the control loop. A regulation contains transfer elements, in which also processes of the tax run off. The control as a whole forms a transmission element in which the reference variable controls the controlled variable as an output variable as an input variable. A human being can also participate as a member of a control loop. (from DIN 19 226 part 1 / 2.94) Control fitting Fitting, intended for use in all switching positions between "closed" or "fully open" Rear seal Contact surfaces of the upper part or the bush in the upper part and the spindle or the corresponding part with fully retracted spindle , Backflow preventer valve which automatically opens when flowing in a predetermined direction and prevents the flow in the opposite direction sebsttätig. Slider valve in which the closure body movement is rectilinear and takes place in the termination region transverse to the flow direction. Welding housing end, which is intended for welding to a corresponding end of a part by butt welding or socket welding. Sealing sleeve end housing end, suitable for connection of a pipe part by plugging in a sleeve and then sealing by fillet weld safety valve A valve that automatically flows out without support by a different energy than that of the medium a proven amount of the medium, so that the exceeding of a predetermined pressure is prevented, and is designed so that it closes again and prevents further outflow of the medium when normal operating pressure conditions are restored. Seat on the closure body Part of the closure body, which forms the seat surface on the closure body. It may be an integral part of the closure body or a separate part. Seat in the housing Part of the housing that forms the stub surface in the housing. It may be an integral part of the closure body or a separate part. Seat surface Contact surfaces of the seat on the closing body and the seat in the housing, which cause the closure of the valve. Seat ring Separate part forming a seat surface. -> Seat ring in the housing and -> Seat ring in the closing body Seat ring on the closing body Separate part built into the housing, which forms the seating surface of the closing body. Seat ring in the housing Separate part built into the housing, which forms a seat surface in the housing. Locking chamber ring Rigid spacer ring in the packing space for separating two packing layers Spindle Passing through the pressure-bearing housing, which transmits the movement of the actuator to the closing body, whereby it moves linearly. Spindle, non-rising spindle, which does not perform linear movement during movement of the closure body. Spindle, rising spindle, which performs a linear movement during the movement of the closing body. Spindle nut Part of the actuating body on the closing body, which, in conjunction with the spindle thread, converts a rotary movement into a linear movement. Control Valve An auxiliary power device that changes the flow in the process system. It consists of a fitting, connected to the drive, which is able to change the position of the throttle body in the valve in response to the control signal. Butt weld end of housing intended for butt welding to a corresponding end of a part by butt welding or socket welding. Symmetrical armature fitting whose inner contours are symmetrical to a plane which is perpendicular to the axis of the housing end openings. Dead space space around the ball Type test Inspection performed on one or more valves, representative of the design and manufacturing process to confirm that the production complies with the specified requirements. Union nut Threaded ring which connects the upper part or the cap with the union nut to the housing. Conduction line, which, with the closure body closed, allows a flow from one side to the other side of the body of the main body.
