    into the pump head. A bypass, which connects the pressure port of the pump to the inlet side, is closed by a spring-loaded diaphragm (see Fig. 4). If the pressure on the pressure side of the pump reaches the setting of the over-pressure relief valve, this opens and circulates liquid through the internal bypass

    ultimate vacuum. Since it has no central perforation, this diaphragm provides practically a hermetic seal between compression space and crankcase. The head, the valve discs and the valve bodies of the FT range are made from PTFE . As already mentioned, the major disadvantage of PTFE is its tendency

    self-operated regulators are to be used. Standard pressure regulators have a range spring that pushes down on the diaphragm to act as a force balance to the pressure being regulated, whether it is downstream pressure as with the common pressure regulating valve (PRV) or upstream as with a back pressure
  • Selection Considerations for Control Valves Versus Regulators
    . A control valve is the final control element in a control system and needs to be evaluated in that context. A control valve is most frequently used in the control of the following parameters: * Temperature * Pressure * Flow * Level However, in principle, any continuously varying system parameter

    diaphragms, which are connected by a common shaft, the two inlet valve balls and the two outlet valve balls. The diaphragms act as a separation membrane between the compressed air supply and the liquid. Driving the diaphragms with compressed air instead of the shaft balances the load on the diaphragm, which

    shutoff is almost impossible. Diaphragm valves consist of a body, bonnet, and a flexible diaphragm that is pushed down by the stem to effect closure. The principal advantage of this type of valve is that the stem seal is eliminated. Diaphragm valves are used primarily for handling viscous fluids
