Key Elektrogas Product Lines Explained

Safety Solenoid Valves (EVRM / VML Series)

The EVRM series covers normally-closed (NC) and normally-open (NA) solenoid valves in threaded connections from D 3/8" through Rp 1¼". These are the most common Elektrogas components found on gas burner trains. Key variants include:

• EVRM NC 1A (ELK15008) — Rp 1/2", 600 mbar max, 12 W, Kvs 4.8 m³/h
• EVRM NC-OA (ELK15006) — D 3/8", 600 mbar max, 12 W, aluminium body, Kvs 8 m³/h
• EVRM NA 3.5 (ELK20014) — Rp 1¼", 500 mbar max, 16 W, IP54, cable gland PG09
• VML 35-60 (ELK12010) — Rp 1 (DN25), 6 bar max, 230 VAC, slow-opening/fast-closing, Kvs 12.0 m³/h

When ordering, always confirm whether you need NC (normally closed, fail-safe shut-off) or NA (normally open) operation, the connection size, maximum working pressure, and supply voltage.

Multibloc Valve Assemblies (VMM Series)

Multibloc units combine two safety solenoid valves, a pressure regulator, and a filter into a single compact body — reducing installation footprint on gas trains. Two representative models:

Slow-opening variants (suffix "S") are preferred where pressure surge protection is required; fast-opening variants (suffix "F") suit applications demanding rapid response.

Hydraulic and Butterfly Valves

For larger-diameter gas lines, Elektrogas offers hydraulic motorised valves and butterfly valves:

• VMH93 DN125 (ELK24008) — Hydraulic valve, Kvs 92.0 m³/h, opening time 10–15 sec, max pressure 1.6 bar, up to 60 cycles/hour
• VF6R DN50 (ELK30004) — Butterfly valve, 0–90° rotation, flange connection, max pressure 500 mbar

Actuator Drives

The SR 4 drive (ELK34002) is a solenoid actuator with 0/90° adjustable rotation, rated for 230 VAC 50/60 Hz and 110 VAC 50/60 Hz, with an ambient temperature range of -15 °C to +60 °C. It is used to motorise butterfly valves and ball valves on gas trains.

Gas Filters

Upstream filtration protects valve seats and regulators from particulate contamination. The FG7-6A (FEK06014) is a flanged gas filter rated to 6 bar with 30 µm filtration, aluminium body, Kvs 6.8 m³/h, and PED certification (PED/0497/3811/20). Check the filter's connection size and pressure rating against your gas train design before ordering a replacement element or complete assembly.

Limit-Switch Contacts and Coils (Spare Parts)

Position feedback is critical for safety interlock circuits. Elektrogas supplies end-of-stroke and limit-switch contacts as separate spare parts:

Both ELK52410 and ELK52210 are adjusted with a 3 mm Allen wrench. ELK52210 carries ATEX category II 3 G,D, making it suitable for Zone 2/22 hazardous-area installations — verify your site classification before specifying.

Replacement coils are also available as spare parts. The 1930.4610 coil (ELK26512) fits EVRMNA/OT valves from 3/8" to 2" at 600 mbar–6 bar, rated 24 VDC, 22 W. Always match coil voltage to the control panel supply.

How to Identify the Correct Elektrogas Part Number

1. Locate the nameplate. Every Elektrogas valve carries a stamped or printed label showing the model designation (e.g. EVRM NC 1A), connection size, and maximum working pressure.
2. Record the connection type and size. Threaded connections are expressed as Rp (BSP parallel) or D (nominal diameter in inches); flanged connections use DN (nominal bore in mm). Do not substitute one standard for another without checking thread compatibility.
3. Note the pressure rating. Elektrogas valves are rated at either 500 mbar, 600 mbar, or 6 bar. Fitting a 500 mbar valve on a 6 bar line is a safety violation.
4. Confirm voltage and power. Coils and solenoid valves are available in 24 VDC, 110 VAC, and 230 VAC variants. Check the coil label or wiring diagram.
5. Check the opening characteristic. Specify slow-opening (S suffix) or fast-opening (F suffix) for multibloc and VML series valves based on your burner management system requirements.
6. Cross-reference with the 3G Electric catalog SKU. Use the model designation from the nameplate to search the catalog; confirm the SKU matches all parameters above before placing an order.

Compatibility Basics

Elektrogas components are designed for use in natural gas, LPG, and mixed-gas applications within the pressure and temperature limits stamped on each unit. When replacing a valve or filter:

• Match the nominal diameter (DN) or threaded connection size exactly — do not upsize or downsize without recalculating Kvs and pressure drop.
• Verify the Kvs flow factor is equal to or greater than the original to avoid starving the burner at full load.
• Confirm the body material is compatible with the gas composition — aluminium bodies (as on ELK15006 and FEK06014) are standard for most natural gas and LPG applications.
• For limit-switch contacts, confirm the ATEX category if the installation is in a classified hazardous area.
• For pressure mounting kits (e.g. ELK61004, G1/4" connection, compatible with LD3/LDM2/LDM3/LDM4 series), verify the instrument port thread on the valve body before ordering.

Frequently Asked Questions

What is the maximum pressure rating for Elektrogas solenoid valves in the 3G Electric catalog?

The highest-rated solenoid valves in the catalog reach 6 bar (e.g. VML 35-60, SKU ELK12010). Most EVRM-series valves are rated to 600 mbar. Always match the valve's rated pressure to your system's maximum operating pressure.

How do I tell whether I need an NC or NA solenoid valve?

NC (normally closed) valves shut off gas when de-energised — the standard choice for safety shut-off duty. NA (normally open) valves open when de-energised, used in specific control logic. Check your burner management system wiring diagram to confirm which fail-safe state is required.

Can I replace just the coil on an Elektrogas EVRM valve?

Yes. Coils are available as separate spare parts. The 1930.4610 coil (SKU ELK26512) fits EVRMNA/OT valves from 3/8" to 2" at 24 VDC, 22 W. Confirm the coil voltage matches your control panel supply before ordering.

What filtration rating do Elektrogas gas filters provide?

The FG7-6A filter (SKU FEK06014) provides 30 µm filtration at up to 6 bar. Check the filter's Kvs (6.8 m³/h) and connection size (flanged) against your gas train design to ensure it is a direct replacement.

Are any Elektrogas limit-switch contacts ATEX-rated?

Yes. The limit switch contact ELK52210 carries ATEX category II 3 G,D, suitable for Zone 2/22 hazardous areas. It is rated to 600 mbar, IP54, for DN65 and DN80 valves. Verify your site's area classification before specifying this component.

What tool is needed to adjust Elektrogas end-of-stroke contacts?

A 3 mm Allen (hex) wrench is required to adjust the end-of-stroke and end-of-travel contacts (ELK52410, ELK52210, ELK52214). No special proprietary tooling is needed for field adjustment.

How do I order Elektrogas parts through 3G Electric if my part is not listed?

Submit a nameplate photograph and the model designation to 3G Electric's technical team. They will identify the current catalog equivalent or source the part directly. All items are available to order; lead time is confirmed at quotation stage.

What is the difference between the VMM405AS10 and VMM805AF10 multibloc valves?

The VMM405AS10 (ELK22017) has a Rp 1" connection and slow-opening characteristic; the VMM805AF10 (ELK22062) has a DN80 connection and fast-opening characteristic. Both are rated to 500 mbar with a D15 right-side by-pass. Select based on your burner management system's required opening speed and pipe size.
