Control valve

The new Sharktooth control valve, available from Yeary Controls, provides excellent throttling characteristics, plus aerodynamic noise attenuation and liquid cavitation reductions. An innovative control cartridge is used to turn triple eccentric butterfly valves into control valves with exceptional control characteristics, as well as Class IV, V, or VI metal-to-metal, fire safe shut-off. They are available in carbon steel, stainless steel and special alloys for liquids, gasses, and steam at temperatures from cryogenic up to 850F in 150, 300 and 600 ANSI pressure classes, from 3" through 48", with a wide choice of actuators and control accessories.

Valve sockets

Reed VKSK Sockets are specifically designed to engage a rounded or corroded gate nut on valves in difficult situations. The sockets attach to a standard gate key with the VKSK's screw and plate. Kits include small, medium, and large sockets which are rugged and durable, yellow-zinc-plated, hardened steel. These special sockets fit regular valve keys. Reed's kit solution is lower cost and lower maintenance than alternative tools used for removing stubborn gate nuts.

Valve actuators

Rotork all-electric, non-intrusive CVA control-valve actuators are available in linear and quarter-turn actions and eliminate the need for air supplies. They provide precise operation, advanced HMI capabilities, and fail-to-position protection as well as energy and maintenance savings. CVA actuators provide control-valve operation with repeatability and resolution performance at <0.1% of full scale. In addition, they include wireless Bluetooth communication technology that can be used for simplified actuator set-up and adjustment.

Valve control

Bernard Controls' Master Station is a turnkey system designed to ease the command and control of many motor operated valves using fieldbus. Compared to traditional point-to-point connection, fieldbus gathers more information while optimizing on-site wiring and reducing the overall cost of installation. In many cases, the control architecture integrates a "Master Station" located between the DCS and the actuators. Combining PLC technology, full redundancy and bus continuity, the station has been designed as a reliable system to protect an installation. Digital communication allows the user to retrieve a large quantity of information from the field units.

Diaphragm valve

The new Type 514-519 High Flow Diaphragm Valve Series from GF Piping Systems valve offers an optimized, turbulence-free flow geometry that provides significantly increased flow rate performance and lower energy consumption. These features expand the valve's suitability for applications where diaphragm valves were previously not considered due to flow restriction. Cv values range from 3.9 to 116.8, depending on size and end connection.

Actuated ball valve

Plast-O-Matic Valves has developed a new electrically actuated polypro ball valve that will automatically accept virtually any input power signal. Designed for pure water and chemical applications, the valves are molded with non-pigmented, plasticizer-free homopolymer resin and are assembled "dry" to eliminate contamination. Available in 3/8" - 2" sizes, the valves meet FDA and NSF requirements. The new Series EBVA electrical actuator is available assembled to the valve and is also sold separately for future field installation.

Gas shutoff system

The Duplex Model II control system from Halogen Valve closes Eclipse actuators on 150 lb. gas cylinder and ton container valves when activated by remote sensors. The newly designed computer system applies 30 foot-pounds of torque for test closures and 50 foot-pounds of torque for emergency closures of cylinder valves. All Fire Codes recognize and approve the "automatic-closing fail-safe shutoff valve" system in lieu of a scrubber treatment system.

Automatic valves

Ooval Valves, distributed by Amiad Filtration, now offers oval-diaphragm automatic valves in 2" and 3" plastic sizes. The company also offers a metal valve line in 2" through 8" sizes. The gentle curves of the valve chamber dramatically reduce cavitation and water hammer, and lowers pressure loss by as much as 300 percent compared to conventional valve designs. The design also improves Cv values by 44 percent over standard valves, nearly doubling flow. The valves feature a unique, flexible oval diaphragm that delivers drip-tight sealing and effective pressure regulation down to 5.8 psi at high or low flow rates.

Butterfly valve

The Henry Pratt HP350 butterfly valve is rated to handle line pressures of up to 350 psi and is offered in both flanged and mechanical joint end connections. Actuation options include buried service nut or handwheel. The valve is available in sizes of 6" through 48" for flanged end connections and 6" through 24" for mechanical joint connections. The valve disc uses a flow through design and seals using the Henry Pratt patented E-LOK seating system.

Check valve

The Tideflex CheckMate™ Inline Check Valve is ideal for backflow prevention and odor mitigation. In outfalls, stormwater, CSO and SSO applications, the custom-engineered, all-rubber unibody design eliminates backflow from oceans, rivers and interceptors. The valve features an elastomer, fabric-reinforced design. It offers low headloss and can open to near full pipe diameter. This maximizes the flow capacity of the outfall, which is particularly beneficial in low-lying areas where limited driving head is available.

Emergency actuators

Robo-Control manufactures battery-operated actuators to remotely open and close hazardous gas cylinder and container valves such as chlorine and sulfur dioxide. The actuators weigh as little as six pounds and mount to the valve independently from existing hardware or dispensers. Each actuator has integral indication for actual valve position and outputs for valve position are available. Some actuators can communicate with an RTU or PLC for SCADA or in-plant control. Integral leak detectors are available to provide immediate closure when a leak is detected.

Inline check valves

The ProFlex 750 from Proco Products is designed to answer enclosed body check valve requirements. It requires no external power sources. The valve's unique design means no mechanical parts to break down or wear, reducing maintenance costs. The inline check valve allows flow of abrasive materials such as raw sewage, sludges or slurries. The elastomer design allows media to flow through without significant head losses and will seal around solids trapped in the valve.

Electronic flow measurement

The OCV ValveMeter Lite is an electronic flow measurement system that can be added to any OCV control valve, ranging from 4" to 24". By adding this system, the electronic unit will give the ability to measure flow through the adapted valve. The user may access the information via digital display on the front of the electronic unit; a 4-20 mA analog output; or an RS232 digital output for the flow rate, totalizer count, measurement scale, and other information. OCV also offers other electronic units for more complex applications.

Insertion valve

Team's InsertValve™ installs under pressure, eliminating the need for line shut downs. Designed for a wide range of line sizes and types, the valve's wedge gate seats on the valve body, not the pipe bottom. This feature prevents the seat from coming into contact with the cut pipe edges and significantly extends valve life. The valve can be repaired under pressure. Team offers professional installation services by trained technicians or packaged solutions ready for line cut-in.
