New portable valve operating system
Easi-Drive, a new portable valve operating system, is designed for use with manual valves in situations where valve size, pressure rating, or work environment would demand a dedicated actuator or require a work crew.
By reducing valve operation to a one-person activity, Easi-Drive helps eliminate operator fatigue and helps reduce the risk of injury
Consisting of three elements—drive gun, valve coupler, and power pack—Easi-Drive is fully portable and adaptable to any size or type of valve. Banks of valves can be managed with a single tool, and it is particularly helpful for moving tight or partially seized valves.
The system is available for operation via three alternative power sources: pneumatic, hydraulic, and electric. It can be run from adjacent plant air or single-phase electrical supply. All torque ranges can be catered for, with variable torque adjustment capability as standard.
Installation is simple and is done by using adapters that either clamp on to the valve handwheel or mount directly on to the valve stem. To operate the valve, the gun is attached to the adapter and connected to a power supply (pneumatic, hydraulic, or electric).

Software update adds security features
Version 3.1 of MDS iNET 900 software offers added security features.
New security features include 128-bit encryption with automatic key rotation and authentication mechanisms. These new features, combined with the iNET 900's frequency hopping spread spectrum technique, help create a secure wireless device, the company says.
The 128-bit encryption masks data and makes it unintelligible to unauthorized parties, and the automatic key rotation mechanism updates the encryption key shared between radios to further enhance security.
The two-way authentication restricts connectivity between an access point and its remotes by ensuring the radios are on each other's lists of acceptable devices with which to communicate.
The iNET 900 is a long-range, high-speed, secure, industrial, wireless IP-Ethernet and Serial solution.
It integrates the functionality of multiple devices into one solution allowing multiple users to run multiple applications and protocols.
Because the iNET operates in the 902 -928 Mhz frequency band, potential hackers cannot use 802.11b wireless LAN cards, which operate in the 2.4 Ghz frequency band, to detect an MDS iNET network, let alone communicate with it.

New clamp-on turbine series insertion flowmeters
This new line of clamp-on insertion turbine flowmeters is designed as an alternative to the plastic paddle wheel type flowmeter.
This insertion type offers stainless steel construction and long-life hybrid ceramic ball bearings.
Meters are offered with additional bearing choices including tungsten carbide and hard carbon composite sleeve. Construction of the clamp-on saddle is offered in CPVC, stainless steel, or ductile iron dependent upon pressure and flow media compatibility. Flow measurement for pipe sizes up to and including 8 in. are available.
All of the firm's signal conditioners, linearizers, transmitters, and totalizer-rate indicators are available to accompany this series and can be flowmeter or remote mounted.

Brochure details hydrogen sulfide removal process
A new brochure, yours free for the request, discusses LO-CAT Total Custom Systems that offer a variety of liquid H2S removal solutions for larger facilities with high H2S loads.
LO-CAT units can be designed to handle airflow rates from a few hundred to several hundred thousand scfm and H2S concentrations from 50 ppmv to several thousand ppmv.
Flexible operations allow 100% turndown in gas flow and H2S concentrations.
The LO-CAT process is a wet scrubbing, liquid redox system that uses a chelated iron solution to convert H2S to innocuous elemental sulfur. Its environmentally safe catalyst does not use toxic chemicals and produces no hazardous waste byproducts. Units can be designed for 99.9+% H2S removal efficiency, the brochure notes.
The technology can be applied to all types of gas streams, including refinery fuel gas, oil production, air, amine acid gas, natural gas, and carbon dioxide.
Brochure highlights include how the system works in aerobic and anaerobic gas streams and how the autocirculation process treats anaerobic, nonexplosive gas streams.
