    Construction Features
    • All welded construction
    • Elimination of elastomeric seals
    • Fabricated from Stainless Steel, High Nickel or Titanium alloys as required by operating parameters

  • Thermal Valves
    All welded, hermetically sealed stainless steel construction — no elastomers. Capable of 1,000,000+ thermal cycles. Actuation and operating temperatures from cryogenic to over 1,000°f. <br /> Repeatable performance with no performance drift over time....

  • • Provides precise movement for a specified temperature range
    • Withstands harsh operating environments
    • High reliability and long life
    • Accurate, repeatable performance
    • All welded stainless steel construction
  • Bellows Dynamic Seals
    We design and manufacture a variety of bellows dynamic seals, ideal for high temperature applications where elastomeric seals break down. Our seals can be circular, square, rectangular, oval – or whatever shape fits your application....

  • Typical applications include:

    • Engine nacelle seals
    • Firewall seals
    • Anti-icing applications
    • Fuel drain seals
    • Engine gearbox seals
    • Engine ducting seals

     The bellows type dymanic face seal offers advantages including:

    • All welded hermetic construction
    • Stainless steel or nigh nickle alloys
    • Availible to include carbon or ceramic inserts for low and high temperature
    • Bellows replaces the secondary o-ring seal - Zero secondary leakage - Uniform (360°) face loading - No sticktion or hysteresis
    • Accurate and repeatable load at length
    • Longer axial stroke capability - Bellows versus wave spring
    • Suitable for extreme temperature environments - Cryogenic to Flame Resistant
  • Pressure Actuators and Fuel Controls
    Bellows fuel controls provide a continuous source of fuel to the propulsion system at the appropriate pressures and temperatures throughout the flight envelope. With over 65 years of experience developing these parts, our pedigree speaks for itself....
