Microsoft’s Darrell Smith Predicts Seahawks Super Bowl Win and Saves Energy. In addition to optimizing energy savings, Darrell collects 500,000,000 data transactions every 24 hours from 125 buildings that occupy 15 million square feet and house 57,000 people. Darrell was kind enough to share how he uses data to make the Microsoft campus one of the most energy efficient complexes on the planet.
Lynxspring Training Streamed Live at Stromquist & Company Part 1: Stromquist & Company had a Lynxspring day at their Atlanta location. We streamed the event live. The following is part one of that Live Steam. In this episode Marc Petock and Clayton Plymil walk us through the Lynxspring portfoilo of building automation products including the JENEsys and Lynxspring CyberPro.
Controlco Partners with Control Network Solutions to Bring Innovation to Lighting Controls: Industry leaders add Big Data capabilities to NiagaraAX® platform. OAKLAND, March, 2014 – Lighting controls demand increasingly more attention from building managers across the globe. In California alone at the end of 2013, the state’s Department of Energy updated its Building Energy Efficiency Program with a lighting requirement that demands multi-level lighting controls (at least three to four levels), putting strain on existing systems that aren’t able to integrate at this volume.
ControlTalk NOW will continue to provide a weekly episode featuring the people, products, and the News of the Week shaping our world of controls, building automation, and the HVAC industry.

If you read Stacies recent post you know our Pneumatics, VAV, and Boiler classes will be coming back to Atlanta this fall. These classes are very popular. Check out this short video ” Peak inside a Stromquist pneumatics class” to see what the class is all about.
As someone once said, “He who hesitates waits, and waits, and waits…maybe that’s why they are called waiters” Think about it why wait ? to reward the non procrastinators call Edna before June 1 and reserve your spot with a $50 deposit and we will give you $75 off on the pneumatics class and we will even give you $20 off on Edge safety sunglasses.
Edna can be reached at 1.800.241.9471
Honeywell has added a new Delphi video presentation to its Environmental and Combustion Controls website.

Boiler contractors see these valves all the time when working on equipment. Generally the steam relief valve is often little understood, often incorrectly installed, and usually neglected. A little refresher on these valves might be in order.
How Relief Valves Work
As the pressure of the steam within a boiler approaches the set pressure of the valve, the steam pressure on the underside of the actuating disc approaches the pressure of a spring applied to the outer side of the disc. When equilibrium is passed, the disc starts to lift off its seat. The moment this happens, steam is suddenly released all around the disc to what is called the “huddling chamber.” This chamber increases the area of the disc that sees steam pressure, thus increasing force. This increased area under steam pressure makes the pressure much more unbalanced in the direction of the valve discharge opening and therefore pops the valve into a wide open position. When the valve opens with a “pop” the valve seat is preserved from wiredraw caused by slow opening.
Closure of the valve occurs only after the boiler pressure is dropped several pounds below the set point. The reduction of the area of the disc seeing steam causes the disc to firmly close against the valve seat.
Relief Valve Installation
Proper installation of a steam relief valve seems somewhat simple and is, as long as two areas of concern are followed.
The first area of concern is valve distortion. Valve distortion occurs when the valve is improperly wrenched in, using the valve body instead of supplied wrench flats. Distortion also occurs when the discharge side of the safety relief valve is made to bear the weight of the discharge piping. To prevent this distortion use a short nipple from the valve to an independently supported bell reducer or drip pan elbow. These valves are precision devices and any distortion will affect accuracy and calibration.
The second area of concern is discharge piping. For a safety valve to do its job it must be sized properly to adequately relieve all the steam the boiler is capable of producing while operating at its maximum. All piping to or from a safety relief valve must be at least as large as the valve’s connections. Also, the restrictive effect of elbows and the friction losses in pipe must be taken into account. For this reason, piping runs should be as short as possible and pipe sizes should be generous.
If you need help in replacing or sizing a steam relief valve please contact Stromquist and Company at 1-800-241-9471. All others can order this product from one of our affiliates at CGNA.
Our newest employee, Paul Morin, recently conducted a training class on installations and terminations. Before coming to work for Stromquist, Paul worked in HVAC contracting so he knows a lot about the industry. He is a very sharp guy and a great teacher. His class covered methods of wiring, different types of wiring and cables, VAV box schedules, mechanical drawings and much more. After the class, those in attendance said it was very beneficial and that they really learned a lot from it. One attendee said that what he learned in the class will definitely help him on future installations and wiring. The class was received so well that we are going to have Paul teach it again after the first of the year. We will post more information on it when we get it scheduled, so be on the lookout and plan to attend if you’re in the Atlanta area.
