New diaphragm valve from Georg Fischer Piping Systems

Twice the flow with optimized flow contours
The new diaphragm valves have decisive advantages in handling and safety, as well as efficiency. The flow in these new valves is twice that of conventional diaphragm valves. In addition, the central plastic thread, which is used in place of the usual four metal screws, guarantees a corrosion-resistant connection.

Not apparent at first glance, but equally important is the more homogenous thermal expansion behavior achieved by the central plastic thread, which eliminates the need for retightening the valve body. The central thread ensures a consistent seat pressure, guaranteeing leak-tightness up to an operating pressure of 16 bar.

New flow contour of the diaphragm valves
The real technological advances of the new generation of diaphragm valves are actually located on the inside. Thanks to the optimized, turbulence-free flow contour the KV value has been doubled. The rounded contours with soft transitions and radii
mean less abrasion and noise transmission, which adds comfort to daily use. The modified geometry of the valve body results in linear control characteristics — and therefore also consistently stable processes.

How the design affects the flow rate of the diaphragm valves can be seen in an independent comparison in which the new diaphragm valves from GF Piping Systems were tested against conventional diaphragm valves. 100% more flow was achieved on average with the optimized, turbulence-free flow contour. And this of course contributes to the economic efficiency of the diaphragm valves with lower running costs and the lower overall cost for media transport.

Material diversity and guaranteed compatibility
A large variety of materials warrant that the valves are compatible with the processes they are used in, thus ensuring safety. Valve bodies can be made of PVC-U, PVC-C, ABS as well as PP-H, PP-n and PVDF, membranes of EPDM, PTFE, FPM and NBR. This range of materials covers nearly the entire spectrum of chemicals with which the diaphragm valves can come into contact. So it makes no difference what type of media needs to be conveyed: From extremely contaminated or solid-containing to highly pure media, from the chemical process industry to microelectronics or water treatment, from cooling to control applications, everything is now possible. The large diversity of connection options means that the valves can be used universally. Compatibility to the global standards for connections, e.g. ISO, BS,
ASTM, ANSI and JIS, as well as to prEN ISO 16138, ISO9393 or EN558 standards have all been taken into consideration. Outer dimensions and connecting dimensions have not been changed from the preceding models. All the new valves are therefore backward compatible and can be built into existing pipelines.

Design diversity
Standard versions of the diaphragm valves are operated manually via an integrated lockable handwheel, which protects against inadvertent manipulation. An optional self-adjusting electrical feedback unit, installed in just a few simple steps, enables automatic control and regulation of piping systems, as well as reliable process monitoring.
Automation of the valves is possible with the Diastar pneumatic valve actuator. Thanks to the three different pressure categories — up to 6 bar, up to 10 bar and up 3/3 to 16 bar — the pneumatically actuated diaphragm valves are quickly and easily integrated into nearly all piping systems. Integrating the valves into system control is no problem with the corresponding interfaces and the wide array of accessories, so individual solutions are always possible.

Welcome to One Hour TV! This is Jim from One Hour Heating & Air Conditioning!

Is your heating system blowing cold air… or your cooling system blowing hot air?
Does one room feel hotter or colder than another?
Is your system constantly running, but nothing seems to be happening?

If so, I have some helpful information that could help your system get back to producing comfortable air. These are the 7 helpful steps you can take:

Step 1 Check your thermostat setting. Make sure it’s properly set to either “heat” or “cool.” Replace the batteries on your programmable thermostat. If heating, set the temperature at least 10 degree warmer than the indoor temperature; if cooling, set it 10 degrees cooler. This will give you a better idea if your system is operating properly.

Step 2 Test your thermostat’s accuracy with another temperature gauge. If they do not match, your thermostat may be out of calibration and needs to be reset. To do so, reference the manufacturer’s instructions.

Step 3 Check the power to your unit. A circuit breaker may be tripped. In that case, flip the switch. This should not happen often—if it does, you should consult a licensed HVAC technician. Also, check the master switches to both your inside and outside units, and make sure both are on and receiving electricity.

Step 4 Press your system’s reset button. By resetting the unit, it can clear some of the minor mechanical issues that may cause the system to act irregularly.

Step 5 Go to the system’s return vent and change your filter. Dirt restricts air flow, can cause problems, and impact the temperature of your home. As a rule of thumb, change your filter every month.

Step 6 Clear grass, weeds, ice, anything that may be obstructing airflow, and clean your condensing unit with a commercial coil cleaner. It’s recommended that you do not open up the unit! Damage can easily be done to the fans and can drastically shorten the life of your system!

Step 7 Make sure none of your air vents are blocked! Nothing should be obstructing them, including drapes and furniture; they can restrict air flow and impact a room’s temperature.

Those are my 7 steps you can take to repair your HVAC system. If your system still acts irregularly after following them, it likely needs servicing.

Our services are not limited to only HVAC maintenance, HVAC installation, and HVAC repair. One Hour Air Conditioning and Heating also is concerned with the QUALITY of the air inside your home. Allergies are a big problem. Statistics prove that often the quality of air inside your home can be worse than outside, due to the home being air tight and accumulating dust, molds, and contaminants. Your air conditioning ducts often harbor many of these contaminants. One Hour Air offers Air Duct Cleaning to promote a healthy indoor environment. Call us today or fill out the form on our website for more information.
