Serving a Wide Variety of Industries and Many Applications
Bellows products provide the moving force to actuate switches, to provide accurate control for regulators, to enable precise measuring gauges, and to ensure reliable sealing of valves. In general, our products can be used in response to temperature or pressure change. They are used in many industries and applications such as; HVAC heating systems, aerospace and automobile applications, medical equipment, measurement and control systems, weight technology, power generation, oil and gas exploration and extraction, semiconductor high purity and vacuum applications, and seals for electrical distribution equipment. These are just a few of the myriad applications and diverse industries served.
Basic and Common Applications
An aneroid assembly is a pressure motor where one side of a bellows assembly (inside the assembly illustrated) is evacuated to form a constant reference pressure against which the changing pressure on the other side is measured and used to produce predictable stroke. A spring for rate control and a stop to prevent excessive stroke from the resulting one atmosphere pressure differential usually are required.
Similar to pressure motors. Pressure supplied by a sealed fill of thermo-sensitive liquid or gas. Thermal effect may be received either on the bellows element direct or at a remote bulb for transmission through flexible tubing. Widely used to operate valves, switches, etc., in response to temperature changes.
