Becker Control Valves Silencer Noise Attenuation

The CVS Control Valve Silencer is a noise attenuating device that is installed immediately downstream of any control valve regulator to provide noise reduction of up to 50 dBA. The CVS is available in a variety of configurations and designs to accommodate almost any natural gas regulation facility. The CVS may be combined with other  Becker noise attenuating products in order to provide additional noise reduction.

Features:

• Reduces noise by up to 50 dBA
• Minimal pressure drop and maximum flow capacity
• Effective over full range of flows and pressures
• Easily retrofit to existing Becker regulators or other manufacturer's regulators
• Inexpensive noise reduction
• Zero maintenance and long-life
• Custom engineering ensures minimal pressure drop resulting in maximum flow capacity

Control Valve Silencer may be combined with other Becker noise attenuating devices for optimum noise reduction:

• Becker Below Grade Ball Valve Regulators
• Becker QTBV Series Quiet Trim Ball Valves
• Becker CVE Series Globe Control Valves equipped with noise trim

Usage:

* High Noise Reduction Applications
* All natural gas control valve applications
* May be specified for new control valve applications
* Easily retrofit to existing regulator stations to eliminate noise problems

  Custom Acoustic Performance

• 
  Computer-aided design allows infinite variations in the parameters of slot width and absorptive acoustic packing length. The optimum combination of these elements is selected to provide the required noise reduction.

Custom Flow Performance

Becker utilizes diffusers and packed sections which provide the exact amount of pressure drop required for each application:

• For high pressure and high noise applications, silencers can be designed to efficiently share pressure drop with the control valve or regulator.
• For low pressure drop requirements, silencers can be designed to minimize pressure loss through the regulator station.
