Non-fluorinated foam concentrate offers outstanding performance for Class B fire protection sprinkler systems
Johnson Controls, a global leader for smart, healthy and sustainable buildings, has launched the new NFF-331 3%x3% Non-Fluorinated Firefighting Foam Concentrate under its ANSUL®, CHEMGUARD® and SKUM® brands. Designed as a flexible and efficient replacement for existing alcohol resistant aqueous film-forming foam (AR-AFFF) concentrates in conventional foam sprinkler systems, the NFF-331 concentrate has been tested and demonstrated to provide excellent fire suppression on a wide range of Class B, hydrocarbon and polar solvent fuel fires.
As the industry transitions toward new solutions to respond to current regulations, many customers are seeking non-fluorinated products to make the trade from legacy products as simple, yet effective, as possible. Whether retrofitting an existing system or designing a new installation, customers can have confidence that NFF-331 foam will deliver the optimum fire suppression performance with minimal water usage to protect their special hazard operations.
NFF-331 foam concentrate has achieved UL 162-listed application rates similar to legacy AR-AFFFs with various upright and pendent sprinklers on hydrocarbon and polar solvent fuels. Listings include some of the lowest non-fluorinated foam application rates for polar solvents in the industry. In addition to quick and effective fire suppression, the low application rates can help simplify system designs, facilitate ease of retrofit and minimize water requirements.
As an alcohol-resistant synthetic fluorine-free foam (AR-SFFF) concentrate, the NFF-331 foam has been tested and UL-listed for suppression of hydrocarbon fuel fires and a broad range of flammable polar hazards, including isopropyl alcohol, ethanol, acetone and other common polar solvents and fuels. It is also EN 1568:2018-rated (Parts 3 and 4) on hydrocarbon and polar solvent fuels.
Ideal for protecting operations that manage flammable liquids, such as warehouses, fuel loading stations and processing facilities (FIG. 2), NFF-331 concentrate is compatible with most conventional foam sprinkler systems. Since water consumption is directly related to application rates, foam sprinkler systems utilizing NFF-331 concentrate may require lower water flow compared to other non-fluorinated foams in the industry. This is especially advantageous for systems with restricted water supplies and benefits new installations since newer systems may be designed for efficiency and optimized resource consumption.
NFF-331 foam concentrate may be proportioned with most conventional, properly calibrated proportioning equipment and is ideal for both fixed and semi-fixed foam systems using sprinklers, nozzles, foam chambers and other standard discharge devices in a wide range of applications. The firefighting concentrate may also be used as an onsite response product and has been compatibility-tested with dry chemical agents in a twin-agent system. Specifiers seeking to retrofit existing systems should consult Johnson Controls technical service experts to review the system requirements for use with NFF-331 foam.

Valve trim manufacturing advances vital to reducing control cavitation
Controlling pressure drop changes in any process operation is vital to plant efficiency and the longevity of components. One of the biggest challenges of having pressure drop points in a plant is that cavitation can occur, causing unnecessary fluid flashing, downstream disruptions, vibrations and physical damage to components. Advances in control valve trim manufacturing are set to alleviate cavitation issues that are costing process and industrial plants thousands of dollars in maintenance, repair and operational (MRO) spending.
Damage caused to components by cavitation can create excessive noise, erosion and pressure transients. In turn, this can result in valve or piping vibration, and potentially fatigue failure of vital control valves.
Cavitation remains an ongoing, disruptive phenomenon that must be addressed to ensure plants and facilities remain as productive as possible. With external factors such as the current energy crisis continuing to squeeze margins for plant operators throughout the oil and gas, power and nuclear industries, the downtime that cavitation can cause is more costly than ever.
Plant stakeholders are strongly encouraged to explore different trim technologies that can limit fluid exit velocities and allow for greater control of the pressure drop let-downs that cause cavitation.
To mitigate cavitation-related downtime, IMI Critical Engineering has developed the 840-3D (globe) (FIG. 4) and 860-3D (angle) control valves. Featuring a customizable 3D-printed trim that uses IMI’s patented DRAG® technology, fluid is directed through a multi-stage path to reduce differential pressure while also eliminating erosion, vibration and noise problems.
Both valves are available in sizes 1 in.–16 in. and are suitable for use across a broad range of applications, benefitting from a top–entry design for easy inspection and maintenance. No internal components are screwed or welded into the valve body, further enabling easy and efficient maintenance and parts replacement. A wide range of actuation is also available, including pneumatic, electric and manual options.
As both the 840-3D and 860-3D provide greater control over fluid velocities, one of the chief causes of cavitation is eliminated at source. Even in situations where gas bubbles may form, the fact that either valve can divide the flow into many small channels is instrumental to reducing energy to consistent and safe levels.
The ability to use 3D printing to manufacture control valve trim components represents a step-change in combatting cavitation. This level of durability and customization is not possible with traditional subtractive manufacturing techniques. While cavitation has long plagued operations teams throughout the oil and gas, power and nuclear industries, the company believes the advent of 3D-printed trim components will finally eliminate one of its chief causes for good.

New gas leak detector is highly sensitive
ION Science has launched its new Panther gas leak detector, featuring a host of new features and twice the sensitivity of its predecessor, the GasCheck G.
The first ever GasCheck was launched in 1990, offering industrial users the ability to detect leaks of gases like hydrogen (H2) and helium (He). Later, more advanced versions were developed with new features, such as over-range protection and audible alarms. The new Panther PRO (FIG. 5) represents a quantum leap in technology, with a highly sensitive thermal conductivity sensor that can rapidly detect a variety of gases—the most popular applications are He, H2, ammonia (NH3) and refrigerants.
The Panther PRO allows users to zero the instrument in ambient air, providing visual, audible and vibration alarms when leaks are detected. A color LCD display and a built-in gas table enables the measurement of concentration and leak rates in a variety of user-selectable units. All measurements can be logged internally and downloaded via Bluetooth or USB. The Panther also features an integrated torch and a flexible probe, which help in low light and restricted areas.
For customers with a smaller budget, a basic Panther model is available that has the same features as the PRO version, but without the data logging and Bluetooth capabilities.
Panther and Panther PRO have been designed for demanding applications and challenging environments, with an internal rechargeable battery that lasts up to 19 hr.

High-performance butterfly valve completes million-cycle test
Flowserve Corp., a leading provider of flow control products and services for the global infrastructure markets, has announced its Valtek® Valdisk™ high-performance butterfly valve is licensor-approved for use in pressure swing adsorption (PSA) applications.
The valve has successfully completed a rigorous 1 MM-cycle endurance test. It is well-suited for applications in chemical plants, oil refineries and other facilities that require control valves that maintain tight shutoff amidst high cycles and bi-directional flows.
The Valtek Valdisk butterfly valve (FIG. 6) joins the Valtek Mark One™ globe valve and Logix™ 3800 digital positioner from Flowserve, which are already licensor-approved for PSA applications. Valtek control valves and Logix automation extend equipment life and maintain purity in PSA skids.
The endurance test simulates the rigorous operating conditions found in high-cycle PSA processes. Conducted in accordance with licensor criteria, the valve was cycled with upstream pressures of 350 psi and measured seat and stem leakage over 1 MM open/close cycles. The valve followed a defined control ramp to demonstrate sensitivity, repeatability and linearity. By increasing valve shutoff reliability, plant operators can maintain accurate pressure in the PSA vessel and extract purer hydrogen, oxygen and nitrogen (or other gases). Increased gas purity and capacities lead to greater production and higher profits.
The Valtek Valdisk valve’s proprietary soft seat design provides long-lasting, Class VI shutoff in both flow directions, and incorporates innovative key features that extend mean-time between repair. The double-offset disc reduces seat and disc wear as well as leakage, extends seat life and reduces maintenance costs. A high-thrust cylinder actuator coupled with an eccentric-cammed disc enables unmatched, high-performance throttling, according to the company. Additionally, its thin body enables a smaller overall PSA skid footprint with lower weight and costs.
Flowserve designed the Valtek Valdisk to ensure process variables remain close to their desired setpoints and improve process productivity, plant uptime and employee safety. Its performance and reliability in PSA applications have been field-proven for more than 30 yr and are now validated by lab testing.
