V901 VANNE ANNULAIRE
« V901 Vanne Annulaire est la vanne appropriée à utiliser chaque fois que les têtes de pression ou les débits doivent être réduits et contrôlés de manière sûre et fiable. La régulation du débit se fait via le mouvement axial d’un piston, actionné par un mécanisme à bielle et manivelle.
Pour pouvoir contrôler la pression et le débit avec précision et finesse, les caractéristiques de contrôle du débit de la vanne doivent être aussi linéaires que possible sur toute la plage d’ouverture. Cela constitue les critères de conception de base des vannes à piston (aiguille) V901. »

Product Features
- High corrosion resistant internal materials
- Lower torques at high pressure rates
- Suitable for flow adjustment
- A ring shaped symmetrical cross section that enables a linear control curve over the entire control range
- The piston’s 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
- 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
- Provides a ring-shaped cross-section in every piston position
- Reliable energy conversion in the middle of the flow stream, which significantly minimises any e ffects of cavitation
- Butterfly and gate valves, due to their design as isolation or shut-o 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
- Through the Computerised Fluid Dynamics (CFD), a very high efficient and optimised plunger valves is designed
- Controls energy conversion from inlet to outlet
- 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
- For proper installation 10 X DN distance of a pipe length should be considered
