\u00ab\u00a0V901 Vanne Annulaire est la vanne appropri\u00e9e \u00e0 utiliser chaque fois que les t\u00eates de pression ou les d\u00e9bits doivent \u00eatre r\u00e9duits et contr\u00f4l\u00e9s de mani\u00e8re s\u00fbre et fiable. La r\u00e9gulation du d\u00e9bit se fait via le mouvement axial d’un piston, actionn\u00e9 par un m\u00e9canisme \u00e0 bielle et manivelle.
\nPour pouvoir contr\u00f4ler la pression et le d\u00e9bit avec pr\u00e9cision et finesse, les caract\u00e9ristiques de contr\u00f4le du d\u00e9bit de la vanne doivent \u00eatre aussi lin\u00e9aires que possible sur toute la plage d’ouverture. Cela constitue les crit\u00e8res de conception de base des vannes \u00e0 piston (aiguille) V901.\u00a0\u00bb<\/p>\n

      Product Features<\/h2>\n
        \n
      1. <\/i>High corrosion resistant internal materials<\/li>\n
      2. <\/i>Lower torques at high pressure rates<\/li>\n
      3. <\/i>Suitable for flow adjustment<\/li>\n
      4. <\/i>A ring shaped symmetrical cross section that enables a linear control curve over the entire control range<\/li>\n
      5. <\/i>The piston\u2019s linear movement results from conversion of the rotary movement of the actuator shaft by the internal slider crank mechanism and ensures a well defined ring-shaped cross- section in every position<\/li>\n
      6. <\/i>Flow streams do not hit each other until they reach the middle of the valve or pipe, which reliably prevents cavitation damage to the valve<\/li>\n
      7. <\/i>Provides a ring-shaped cross-section in every piston position<\/li>\n
      8. <\/i>Reliable energy conversion in the middle of the flow stream, which significantly minimises any e\u001dffects of cavitation<\/li>\n
      9. <\/i>Butterfly and gate valves, due to their design as isolation or shut-o\u001d valves are not suitable for continuous use as a variable flow control valve, with the unique design properties V901 Plunger Valves are able to control the flow continously<\/li>\n
      10. <\/i>Through the Computerised Fluid Dynamics (CFD), a very high efficient and optimised plunger valves is designed<\/li>\n
      11. <\/i>Controls energy conversion from inlet to outlet<\/li>\n
      12. <\/i>The piston is positioned in the center of the valve body and operates in a chamber precisely shaped in order to avoid noises and cavitation damages<\/li>\n
      13. <\/i>For proper installation 10 X DN distance of a pipe length should be considered<\/li>\n<\/ol>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
