    the lower part of the launcher is constructed of a stainless steel framework, within which the vehicle is stored. pressure hulls for electronic devices, a winch, a secondary cable drum and two electric transformers are located in the upper part of the launcher. the samplers include a gravity core sampler and a bottom grab sampler.

  • atmospheric diving suit

    an atmospheric diving suit ads is a small one-person articulated anthropomorphic submersible which resembles a suit of armour, with elaborate pressure joints to allow articulation while maintaining an internal pressure of one atmosphere.the ads can be used for very deep dives of up to 2,300 feet 700 m for many hours, and eliminates the majority of significant physiological dangers .

  • swimfin

    these include stainless steel spring straps and bungee straps, which once set up, are not adjustable, and which reduce the number of potential failure points and places where the fin can snag on obstructions like net, line and seaweed. some heel straps have a loop for better grip with wet hands or gloves. some fins designed for surf use have .

  • gate valve

    gate valves may have flanged ends drilled according to pipeline-compatible flange dimensional standards. gate valves are typically constructed from cast iron, cast carbon steel, ductile iron, gunmetal, stainless steel, alloy steels, and forged steels. all-metal gate valves are used in ultra-high vacuum chambers to isolate regions of the chamber. typical use valve construction knife gate valve imagesglobe valve

    a globe valve, different from ball valve, is a type of valve used for regulating flow in a pipeline, consisting of a movable plug or disc element and a stationary ring seat in a generally spherical body. globe valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle.
