The AM10 3-speed hydronic pumps were designed to extend the range of the company’s AquaMotion pump offerings. 

The valves are available in lead-free alloys with tamper-resistant caps, and sweat, Nation Pipe Thread (NPT), Pex, or chlorinated polyvinyl chloride (CPVC) union connections.  

Installation of the 2-Port Isolation Valve (2PIV) provides quick and easy refrigerant leak detection in evaporators, condenser coils, and refrigerant line sets. 

For engineers, distributors, and installers, FastFind™ Pump Selector is an interactive Web-based ductless mini-split condensate-pump selection tool. 

The NEWS was very busy at the AHR Expo in New York City, visiting as many booths as possible in search of new products. Here is a comprehensive list of all the components and accessories we found on the show floor.

Joe Marchese explains the refrigerant flow control device, which prevents the refrigerant pressure in an evaporator from operating below a minimum value, and discusses how to select the right one for the job. 

A new line of hydraulic and pneumatic hand-calibration pressure pumps includes the PV10K hydraulic calibration pressure pump and PV600 combination pneumatic pressure and vacuum calibration pump. 

The Taco SelfSensing Series with ProBalance™ integrates KV or KS pumps with a variable frequency drive. 

The thermostatic expansion valve (TXV or TEV) is a metering device located between the liquid line and the evaporator. 

The webinar will help field-service technicians gain a better understanding of the function and operation of, as well as key troubleshooting strategies for, stepper motor and pulse-width-modulating electronic expansion valves.
