Water control valve
The Circuit Solver Thermostatic Recirculation Valve (TRV) from Therm-Omega-Tech eliminates oversize recirculating pumps, minimizes heat loss, and lowers flow in hot water return lines.
The Circuit Solver Thermostatic Recirculation Valve (TRV) from Therm-Omega-Tech eliminates oversize recirculating pumps, minimizes heat loss, and lowers flow in hot water return lines. Installed on each hot water supply branch line immediately downstream of the last runout to a hot tap, this valve includes a thermal actuator that opens or closes to establish a flow rate that maintains water temperature within 3 F of the setpoint. This TRV is available for a multibranch domestic hot water system or a system with no branches, saving energy by modulating flow to precisely match system heat loss. It is rated for at least 200,000 cycles, is NSF-61 certified, and meets ANSI/AWWA C800.
Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
