![]() One barge with lifting arms is positioned and moored on each side of the platform. Each lifting arm is equipped with a buoyancy tank on the inside (between the barge and the platform) and a ballast tank on the outside. Each lifting arm is hinged to the skid structure at the center of the barge. The lift arms are supported by a saddle on a skid structure on board the barges. The size of each barge is 120 by 43 by 8 m. It consists of 2 customized barges, 6-12 lift arm systems, and 1 heavy transport vessel or barge for transport to port or a new site. The twin marine lifter (TML) system is based on buoyancy and ballast tanks and lifting arms located on barges. Offshore heavy-lift systemĪ new offshore heavy-lift system promises to provide safe, cost effective, and environmentally friendly solutions Source: ControlAir Inc., 8 Columbia Drive, Amherst, NH 03031. The unit is suited for valve actuation applications on gas transmission and distribution pipe lines, SCADA operated systems, and DCS operations. ![]() Flow capacity is 5 scfm, and relief capacity is 1.4 scfm. Its temperature range is -40° to +150° F. The converter is available with a 12 v dc or 24 v dc motor and four motor speeds. the stainless in-line filter protects against potential contamination in the supply line. The stainless steel construction of the main regulating valve helps prevent corrosion and ensures long, uninterrupted operation. The explosionproof, NENMA7X enclosure and stainless steel regulator construction allow the unit to not only operate in remote, hazardous area applications but also withstand the forces of hostile environments. ![]() Another set of switches provides feedback, which informs the operator (remote or on-site) whether the valve being controlled is in an open or closed state. The converter comes with limit switches that help prevent motor burnout by automatically stopping the motor when the high or low set point is reached. If there is a power failure at the site, the regulated output pressure and valve position remain the same. The rest of the time the 1200 simply acts as a spring-operated regulator.Īnother feature is fail-safe operation. This unit has no power consumption except when the motor is being operated to change the pressure setting. diaphragm controlled pressure-regulating valve and converts the dc signal to a variable pneumatic output. It uses an electronically operated reversible 24 v dc motor, which accurately positions the stainless steel. The Type 1200 Eltop electric to pneumatic converter is a rugged, low power consumption pressure regulator designed for remote locations. Controlair distinguishes itself from competitors in the unique ability to adapt its products to customer-specific applications through joint development projects and strategic design partnerships.Remote site electric to pneumatic converter Click here to enlarge image These products include current-to-pressure (i/p) transducers, voltage-to-pressure (e/p)transducers, pneumatic-to-current (p/i) transducers, precision air pressure regulators, filter regulators, volume boosters, motorized regulators, rolling diaphragm air cylinders and custom engineered devices. The company has an excellent reputation for high performance, quality products.
