Entek Environmental Technologies’ new control valve for water conditioning systems features a new cover for product differentiation, the ability to program a dealer’s name and phone number on the LCD, salt monitoring and audible alarm to indicate when salt needs to be added, the ability to program service alerts, and greater efficiency for reduced salt and water usage.
AWWA CEO David LaFrance thanks water professionals nationwide for keeping water safe for drinking
Dec. 16, 2014, marked the 40th anniversary of the Safe Drinking Water Act (SDWA), which today includes regulations for more than 90 contaminants. American Water Works Assn. (AWWA) CEO David LaFrance issued the following statement to mark the occasion.
New automatic control valves build on the reliability and ease of use provided by the ZW209 pressure-reducing valve. The new valve offerings address multiple end connection options, pressure ratings, ANSI/AWWA standards, functionalities, and a wide range of applications and uses, including commercial, education, healthcare, industrial, irrigation, penal, retail, waterworks and fire protection.
The Wilkins ZW204 non-modulating float valve maintains accurate fluid levels in tanks or reservoirs. It is equipped for threaded connections from 1.25 to 3 in., and flanged for grooved ends from 1.25 to 10 in. The Wilkins ZW205FP Fire Protection Pilot-Operated pressure relief valve is equipped for threaded connections from 2 to 3 in., and flanged for grooved ends from 2 to 10 in. The Wilkins P4000A Fire Protection thermal expansion relief valve relieves excess pressure buildup.
The MNRUB water control valve is an alternative to machined brass valves. It has thermoplastic injection molding on the three plastic valve body components and transfer molding on the NSF 61-compliant, chloramine-resistant rubber seals and O-rings. Through the use of finite element analysis, wall thickness is optimized, conserving plastic material while increasing overall valve strength with less weight and reducing total cost. It has a non-corrosive reinforced thermoplastic body. Each welded valve is leak and pressure tested prior to shipping.

The WS1 Twin Alternating control valve maximizes softener capacity and optimizes salt efficiency. This 1-in. valve provides a service flow rate up to 30 gpm and a backwash flow rate up to 16 gpm, with the meter and bypass installed. It has backwash and brining capabilities up to a 21-in.-diameter mineral tank. It incorporates patented seal-spacer stack assembly and patented technologies from the WS1 and WS3 valves.
The RevV4 rotary control valve analyzes real-world operating conditions for optimal efficiency and is designed with two highly-polished ceramic discs. This engineering advancement eliminates the traditional control valve’s use of pistons and seals, and also reduces noise level during operation. The valve’s flow rates, advanced programming options, interlocking capabilities and a 32-mm distributor tube make it ideal for both residential and light commercial applications.
