Valtek Severe Service EquipmentMegaStream Vent SilencersMegaStream Vent SilencersIn a blowoff or vent system, tremendous energy in theform of noise is released at the open exit. Vent silencersattenuate this noise energy before it is released to theoutside environment. MegaStream vent silencers arevery effective in attenuating very high noise levelscreated when high pressure gases are released to theatmosphere. When engineered in conjunction with anupstream control valve, the entire system can be optimizedto attenuate the noise in smaller, less expensivesolutions. Flowserve engineers can provide an optimizedsolution when presented with both the controlvalve and silencer requirements. (See Figure 38.)The MegaStream vent silencer is available in a varietyof materials, and mounting configurations. The modelnumber for MegaStream vent silencers is GDV.MegaStream vent silencers are custom designedfor maximum noise attenuation.

Valtek Severe Service EquipmentMegaStream In-line SilencersIntroductionFor pipe noise applications beyond the range ofMegaStream plates and diffusers, or control valve severeservice trim, Flowserve provides an in-line silencer(Figure 36), which may be installed separately or inseries with one of the other devices. The Valtek silencerconsists of a series of tuned chambers and tubes filledwith sound absorbing material (Figure 40), and is designedwith staged pressure reduction.As with MegaStream vent silencers, in-line silencersare also custom designed for maximum noise attenuation.Contact factory for dimensions.Figure 39: MegaStream In-line SilencerFigure 40: Construction of MegaStream In-line SilencerFlowserve Corporation, Valtek Control Products, Tel.
