Senior Aerospace Metal Bellows - Dynamic Bellows Seals & Seal Assemblies

Senior designs and manufactures a variety of bellows dynamic seals, ideal for high temperature applications where elastomeric seals break down.

Typical applications include engine nacelle seals, firewall seal, fuel drain seal, and engine duct seals. (read more)

Senior Aerospace Metal Bellows - High Pressure Bellows - Patent pending technology

Senior has developed a patent pending bellows technology for use in gas charged valves, such as gas lift or chemical injection valves. This bellows technology is capable of operating in pressures up to 15,000 PSIG and 100,000 or more cycles. The High Pressure Bellows Seal typically uses a double bellows arrangement. (read more)

Senior Aerospace Metal Bellows - Bellows 101

What is a welded metal bellows? A welded metal bellows is a zero leakage dynamic seal capable of a great range of motion and manufactured from sheet stock. The material of construction may be stainless steel, high nickel alloys, titanium or other alloys to suit the application requirements. (read more)

Senior Aerospace Metal Bellows - Actuators last 10 years or greater

Since 1955, Senior Aerospace Metal Bellows has designed and manufactured millions of sophisticated systems and components for military and commercial aircraft, space shuttles, and satellites. Senior's systems and components have been engineered to extremely precise tolerances for the most demanding applications (read more)

Senior Aerospace Metal Bellows - Temperature sensing, actuation & valve function

Senior also designs and manufactures Thermal Control Valves (TCV). The TCV integrates the temperature sensing, actuaton and valve function into a neat, compact package. These designs may also include pressure relief as required. (read more)
