Elektrogas solenoid valves are some of the most popular items we carry. We often get questions about their electrical components, enclosure ratings, etc. Here are some of the most commonly occurring questions in a handy FAQ.
Voltage
Q: I have standardized on 24V for the systems I sell. That means I need valves with main power and proof of closure for 24V. Can Elektrogas accommodate me? Are there any limitations?
A: Elektrogas valves are available in 24V AC/DC versions, and our proof of closure devices are suitable for 24V. However, there is a current difference between the P and P6 models. (Please see chart below) 24V is only available for models with 3 PSI max.
Q: Do I have to buy that plug if I’m not going to use it?
A: 24V valves in sizes up to and including 1” may be used with either 24V AC or 24V DC. For larger valves, we must know whether 24 AC or 24V DC will be used at the time of order. 24V is now also available for 90 PSI models.
DIN Plug
Q: Is the plug-and-socket electrical connection standard?
A: The T1 version (plug-and-socket with LED to indicate power) is the version we stock in Kent, OH. We recommend the plug-and-socket because there’s not a lot of space inside the electrical box for the wire gauge typically used in the USA.
Q: I see in the literature that these valves are available for 24V AC/DC. Does that mean I can use either AC or DC with the valves?
A: You can certainly order the valves without the plug-and-socket if you like.
Low Power Mode
Q: I’m looking at the power consumption chart in the technical document, and I don’t understand why there are two numbers for each valve. Can you explain that to me?
A: Where possible, the FM style valves are supplied with a low power board as standard. The low power board uses an opening wattage (value O) to open the valve and then switches to a lower holding wattage (H) to hold the valve open. This allows for power savings in many applications.
NEMA rating
Q: What is the NEMA rating for the valves?
A: The valves are not NEMA rated. The enclosure rating used in Europe is IP. The standard valve is rated IP 54. Optionally, the valves can be rated IP 65.
Q: Can I use them outdoors?
A: IP65 rated valves can be used outside, but they must have some type of roof over them. This is primarily to shield them from exposure direct sunlight, which can cause valves to require replacement frequently.
