  • Spring Return Electric Actuators Meet Fire Standards for Tunnels
    with mechanical springs that close (or open) the damper upon loss of power at the actuator. Further, the motorized dampers must function at elevated temperatures to be effective. The ProMation PA series of spring return quarter turn, fail-safe electric actuators successfully performed a high temperature
  • Electric Spring Return Actuators Meet Fire Standards for Tunnels
    In an emergency situation such a fire inside a tunnel, electric motor operated dampers in the ventilation system can act to clear smoke from the structure as well as to suppress spreading of the fire.
  • PolySlide Ballistic Failure Mode?
    Q: "What can be expected as a resultant failure mode of the PolySlide TM composite cylinder if an internal return spring fails (fractures) during operation?" A: The most popular projectile related failure theories for composite cylinders are those that are simplest to use and applicable to general
  • Bellows let chip testers run hot and cold
    in the test chamber. Servometer assembles customized bellows incorporating adjustable return springs and end caps that Aseco supplies. Depending on end-user specs, each S-170 has up to seven bellows actuators arrayed along the chip
  • Bellows smooth valve moves
    electrodeposited nickel bellows connected by a common orifice. With the turbine shut down, the valve-poppet return spring forces damping oil into the first bellows. On start-up, gas pressure on a diaphragm compresses the first bellows and displaces oil into the second. As the turbine runs, oil constantly
  • Permanent Set
    Simply put, permanent set in a compression spring is a condition where the spring is deflected (compressed) and does not return to its original free length. This occurs when the material is deflected beyond its elastic properties. The amount of material in the spring is insufficient to carry
  • Slotted Pin Inflexibility Leads to Failure
    A "Spring Pin" is appropriately named by its ability to flex into a hole that is smaller than the pin's original (pre-installed) outside diameter. A Spring Pin's tendency to return to its original shape after installation makes the pin self retaining. Retention is established by friction between
  • Door Jamb Switch
    Door Jamb Switch with Boot Can be used in a variety of momentary applications where a small switch is required. Black rubber boot covers and protects the face of the switch. SPST Normally closed: Off with plunger depressed, spring return to On. 4A at 12V DC lamp load. Two brass terminals.
