Composite Solenoid Valve Targets Water Purification and Conditioning Applications

ASCO Numatics, based in Florham Park, N.J., has introduced the 212 Series of composite solenoid valves that incorporate the new FasN universal connection system. The 212 Series has been designed specifically for water purification and conditioning systems in commercial and industrial applications.

The 212 Series valves are molded from 30 percent glass-fiber-reinforced polyphenylene ether (PPE) engineering plastic. “With the 212 Series, ASCO has perfected composite valve technology,” claims Robert W. Kemple, Jr., executive vice president of sales and marketing in the Americas for ASCO Numatics. “This is the highly reliable, easy-to-install product the market has been waiting for. It solves the breakdown and reliability problems found in other types of composite valves and is available with one of the fastest delivery times in the industry.”

Notes Anne-Sophie Kedad-Chambareau, who handles commercial segment marketing for ASCO Numatics, which is a business unit of Emerson Industrial Automation, “We noticed external leakage on some of the [competing] valve offerings after a few thousand cycles when they had been tested in our lab. The 212 Series has been tested in our lab for up to 1 million cycles without any external or internal leakage noticed.” The long life of the 212 Series is attributed to highly reliable coils and the highly robust engineered diaphragm, which also contributes to minimal service requirements.

ASCO Numatics’ 212 Series of composite solenoid valves incorporate a universal connection system for water purification and conditioning systems in commercial and industrial applications.

This durability has been realized primarily through the lightweight engineered plastic body. The 212 Series also has what are said to be the highest pressure and temperature ratings on the market: up to 150 psi and 180 deg F.

The composite valve has been tested and certified by NSF International: NSF 61 Annex G (drinking water), NSF 169 (special purpose food equipment and devices) and NSF 372 (lead-free). It also has been tested and certified against NSF Standard 42 for materials and structural requirements. The NSF certification program is accredited by the Standard Council of Canada and ANSI.

The 212 Series comes with ASCO’s FasN universal connection system — reportedly the fastest, most secure valve connection technology that enables the customer to choose between different end connections. With FasN, the valve quickly connects to any type of fitting — all threaded pipe types with NPT threads; copper or PEX tubing with turn and lock (the turn and lock end connection enables a push-in fitting system secured with a locking nut; or PVC plastic with solvent bond — for the most rapid assembly, lowest cost and greatest design flexibility.

There are three potential cost savings associated with using the FasN connection system:

1. Labor cost reduction, as it reduces the installation and mounting time. The FasN connection system is said to be easily adaptable to the pipe.

2. Material and inventory cost reduction. In some cases, reverse osmosis (RO) system providers need to combine different pipe types in their system. For example, the RO systems can require a PEX tubing at the inlet and a solvent bond tubing at the outlet. The manufacturer will no longer have to use an additional fitting to handle those needs: in this particular case, 212 Series composite valves will be equipped with two different end connection types: turn and lock at the inlet and solvent bond at the outlet. Further, a specific ordering code is available for any configuration the customer may need.

3. Cost savings while maintaining the system as the valve can be removed and replaced without dismounting the FasN end connection from the pipes.

The ASCO composite valve is said to be ideal for the following RO and misting applications:

• Food and beverage – offers superior taste and increased cost savings

• Restaurants – improves steamer operations

• Grocery stores – prevents scaling in vegetable misters

• Humidification – reduces scaling and dusting

• Boilers – increases energy efficiency

• Water jet cutting – improves operating efficiencies and extends orifice life

“The 212 Series is well suited for applications where exceptional quality, assured operation and minimal service and warranty costs are essential,” said Kemple. “Now OEMs can get the most reliable, easy-to-assemble composite valve, right now.” ASCO Numatics defines “exceptional quality” as being the 212 valve ratings, combined with NSF certifications and superior reliability, “making this valve the best choice for these market applications.”
