Valve for adjusting the rate of flow of a gaseous fluid

摘要: Valve for adjusting the rate of flow a gaseous fluid, comprising valve body (1) having side inlet (2) and an outlet (3), obturator (10) movable in translation within housing (4) bearing on seat (18) when (3) is shut off, said being fastened by means (5) located externally fluid path. The mobile has front part (9) form hollow cylinder surrounding with limited clearance nose-piece (7) attached to rigid arms (4). surface (17) extended (16) (6) are aerodynamic shape. Reduction effects unsteady forces across full range openings without head losses fully open.
