Product DescriptionL-40700 high Performance control valve with good dynamic stability that is suitable for severe service conditions. In this structure, the fluid often flows from the outside of the cage to its inside. Thus the jet impact and flocculating flow are controlled within the cage, the down stream fluids of a stable point are formed, the large scale effect is reduced. Therefore noise is reduced and the frequency spectrum that produces noise is changed. Valve lower the noise by 15~20 db. Through narrow the hole diameter on the cage, the noise can be further reduced. This structure is called single-stage multi-hole type(SS), and the noise can be reduced by about 5 db.Product Parameters(1)Trim: Cage Guided  Balance Trim                Multi-hole pressure drop                Double Seat or Single Seat with Seal Ring(2)Body : Straight Angle Z type(3)Bonnet: Standard Steam  Cryogenic         (4)Temperature Range : -196℃~570℃(5)Plug sealing : Standard  Graphite  Bellows(6)Leakage : CLASS V（Standard,Metal Seat）                     CLASS VI（Optional,Soft Seat）(7)Pipe Line Connection : Flange  Welding(8)Range ability : 30:1
