New antitamper lock
By helping to ensure that valves and actuators are only operated by authorized individuals, this new antitamper lock (ATL) helps secure company assets by reducing the risk of human error or deliberate tampering.
The way ATL works is simple: the standard condition of the device in service is locked (key free), with the handwheel free-rotating. The standard unit is available in two sizes to suit all lever and handwheel operated valves.
Operation involves three steps: 1) a coded key from the control authority is inserted, engaging the drive; 2) the valve is operated to the desired position; 3) the key is removed, and the valve is locked in the desired position.
Because the lock base adapter is machined to suit host equipment, which can be done on site or supplied already machined to specification, the ATL helps reduce costs, the firm says. Also, as this process replaces existing handwheels or levers, the integrity of pressure envelopes is not compromised, the firm adds.
Because the ATL is only installed and commissioned once, permit to work and lockout-tagout authorities can focus their attention on other matters rather than worrying whether the engineer has installed the lockout device correctly.
The ATL's housing is stainless steel coated with yellow polyester resin. For safety applications, the internal components are made from stainless steel 304, with acetyl bearings, while for security applications these components are manufactured from hardened steel, with a protective security skirt. Both versions can operate in temperatures of –58° F. to +212° F.

New torch consumables aid thin-plate metal cutting
New FineCut consumables for users of the Powermax line of plasma cutting torches and systems promise improvements in cut quality on thin-plate metals by providing a narrower kerf width, virtually no heat-affected zone, and a reduction in dross.
The consumables are designed to be used on the Powermax380, 600, 1000, 1250, and 1650, as well as on comparable legacy systems. They are available immediately in a FineCut starter kit that includes five nozzles, two swirl rings, five electrodes, a deflector cap, five o-rings, and a tube of silicone lubricant.

Pressure transmitter line now offers seven models
The PressureSaver pressure transmitter line has been expanded to include seven models, with a ±0.07% of reading accuracy depending upon model. All come in explosionproof housings with or without windows.
Other features of the expanded line include:
Versatility—split architecture to enable remote mounting nearly anywhere.
Ease-of-use—available with plug-in-display option.
Reliability—automatic self-calibrating plus field-proved design.
Turndown of 100:1 results in efficiency and savings with one unit able to cover many pressure ranges.

New, large, heavy-duty maintenance lift
A new series of large platform lifts is designed for maintenance work.
A riser platform is installed on the main deck, and the lift can be equipped with an engine cradle or circular steps to encompass the engine and provide access on all sides.
The unit is equipped with pneumatic tires with roller bearing mounted wheels for mobility and steering; it can be towed or self-propelled. The deck has foldable steps for ground level access, 42 in. high railings on all sides, and a self-closing entry gate.
Sections of the railing can be folded or removed to clear the path of any obstacles.
Capacities available are 1,000-10,000 lb. Lifting is hydraulically operated, and the hydraulic system is equipped with safety relief valves to prevent overloading. A variety of power sources is available, such as 110 v and 220 v AC single phase, 220-440 v three phase, air powered for hazardous duty operations, diesel engine, or propane-operated engine.
The deck size of the unit shown here is 96 in. wide with 36 in. leaf extension, 20 ft long with 14 ft of lift height. Other sizes are available from 60 in. to 144 in. wide and 72-480 in. in length and vertical lift up to 46 ft height.
The higher lift units are equipped with stabilizing outriggers that telescope out from under the unit. Another option available is a telescopic deck extension along the length or width.
