Senior Operations LLC Metal Bellows has developed a high pressure bellows seal, the DELTA P, for use in injection valve applications. The DELTA P is capable of withstanding high external system pressures, while maintaining low differential pressure across the edge welded bellows. This low differential pressure feature enables the bellows to be designed with thinner material, which increases the stroking and cycle life capability. This bellows seal is ideal for use in gas lift valve applications. 

The following are the main features and benefits of the DELTA P:

  • Dome pressure: 1,000 to 15,000PSIG
  • Injection pressure: 1,000 to 15,000PSIG
  • 20,000 cycles minimum
  • Inconel 718/625 bellows
  • Incaloy 945/945X housing
