    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
    • Rotary shaft 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....

  • Accurate repeatable response to changes on pressure, superior linearity, and low hysteresis. Applications and benefits include:

    • Aircraft engine hydromechanical fuel controls
    • Aneroids for environmental control systems, ejection seats, etc
    • Safety – no membranes to fail/replace. Can include pressurized options, as needed
    • Provides hermetic, zero leakage, clean actuation
    • Operates in extremely harsh environments
    • No elastomers for smooth continuous motion.
    • Optional integrated position sensing with automatic temperature compensation
    • Precision guiding for accuracy and repeatability
    • Individually tuned for synchronous motion
    • Very wide operating temperature range
    •  1,000,000+ lifecycle
  • Bellows Vacuum Pumps and Compressors
    No Maintenance – No wearing surfaces and no lubrication required. Motor and driver assembly contain permanently lubricated bearings. Our hermetically sealed pumps provide contamination free service for millions or billions of cycles....

    • Long Life – Capable of a minimum of 10,000 hours continuous operation
    • Stainless Steel Construction – All wetted surfaces are corrosion resistant stainless steel except for valve assembly gaskets that are either Teflon or Viton
    • Every pump is tested to assure leak tight integrity to mass spectrometer levels
    • Infinite Number of Cycles – Bellows and valves are designed with stress levels below defined endurance limits of materials allowing for an infinite number of cycles
    • Sealed Ball Bearings – Driver assembly containing permanently lubricated and sealed ball bearings
    • Positive Bellows Displacement – Eccentric cams are mounted on the motor output shaft and the rotary motion of the motor is converted to reciprocating motion at the bellows via connecting rods that provide motion for positive bellows displacement
