When his voice rises to a quaver on the bridge of A-side “True Love” (titled sardonically of course) and he belts “well it hurts so bad / just won’t go away,” it shares a common method with country music (simple, somewhat generic lyrics delivered with a force that renders them...
The valve is particularly intended for use in a line to shut off and control the flow of cryogenic propellant. It comprises a seat (2) a closure member (5) in a rigid material and an actuated valve stem (6) guided directly or indirectly in the valve housing (1). The closure member ...

Analytic and computer models of the drive of the DAPS-22.000 shut-off valve are developed and a technique for calculating and applying an estimate of the torque developed by the drive as a function of the angle of deflection of the shaft of the rocker arm is proposed. The three-dimensional...
This paper describes the probabilistic nonlinear analysis of the containment hermetic cover ofmain shut-off valve (MSV) under an extreme internal overpressure and temperature. The scenario ofthe hard accident in NPP and the methodology of the calculation of the fragility curve of the failure...
Shut-off valve for pipelines laid under plasterZWINK,HELMUT
In a high-pressure check valve (shut-off valve), particularly in a hydraulic pressure system with a high fluid delivery capacity, the pressure device for the valve element has a number of pressure rings, which are arranged as a stack and can be moved essentially in the axial direction, i....
