High-Speed Compressor Valve

The Ring Damped Valve is a new breed of plate valve for high-speed reciprocating compressors. It lasts longer and reduces energy costs by up to 10% compared to conventional valves.

Superior Reliability, Run Times

The Ring Damped Valve incorporates a patented damping ring to slow the velocity of the sealing element before it contacts the guard during valve opening. The reduction in speed minimizes the impact forces applied on the sealing element, extending the useful life of the valve assembly. It also allows the valve to run at higher lifts than traditional valves, providing increased effective flow area.

Greater Efficiency, Energy Savings

Higher lifts and unique design features in the Ring Damped Valve produce an effective flow area that is 10% larger (on average) than plate valves of similar size. The increased flow results in a 10% reduction in energy usage by the compressor.

For most applications, energy savings alone will ensure a 100% return on investment within one year of operation.

Advantages

  • Higher lift increases flow, cuts energy usage by an average of 10%
  • Damping ring reduces impact forces for longer valve life
  • Precision-engineered springs ensure timely closing
  • Standard threaded washer facilitates valve installation and removal
  • Maximum flow is achieved through optimum combination of port row widths and pitch circles
  • Reinforced plate material protects against impact fatigue
  • Heavy-duty springs withstand high speeds and lifts up to 0.150 inch (3.8 mm)
  • Superior materials provide high resistance to corrosion and wear

Typical Applications

High-speed, short-stroke gas compressors in:

  • Natural gas transportation and storage
  • Natural gas production
  • Refining
  • Chemical and petrochemical processes
