WebFixed-orifice, pressure-compensated flow controls provide precise flow regulation for meter-in or meter-out applications where there may be wide pressure fluctuations. A variety of flow rates are available. The sharp-edged orifice design minimizes flow variations due to viscosity changes. Will accept 5000 psi (350 bar) at ports 1 and 2. WebStandard XP*B Priority Flow Control Solutions:Adjustable orifice using the NF** needle valve. In the XP*B, the priority flow control manifold divides the inlet flow of port P into a priority flow to port CF with the excess flow going to port EF. The priority flow can easily be adjusted for specific applications using the NF** needle valve.
