DN80 Safety Solenoid Valve

Elektrogas fast opening solenoid valve VML Model Safety Solenoid Valve For Gas Power Burners

Safety solenoid valves for air and gas slow opening and fast closing

 

Functioning and application

The VML type valve is a safety shutting device using auxiliary power supply.

When it is de-energized, the spring pushes on the seal disc, keeping the gas passage closed.Now, the inlet chamber is under the gas line pressure which forces on the disc, increasing the closing function and improving the seal.

When the coil is powered the valve opens rapidly, against the strength of the spring and gas pressure. The flow may be adjusted using the regulating screw on the top (see the installation and service instructions).

If the power supply is shut off, the valve rapidly closes, interrupting the gas flow.

 

Elektrogas brand from Italy VML type valve is a safety valve that is normally closed, with fast or slow opening and adjustable rapid section for initial gas flow. When not in working position the spring works on the disc keeping the gas passage closed. When the coil is powered the valve opens rapidly in the first section of the flow, then slowly, with adjust-able speed. When power is switched off the valve rapidly shuts.

This type of device is suitable for gas and air blocking and adjusting controls in atmospheric burners or fan-assisted burners, in industrial kilns and in all gas equipments which use gas solenoid valves (qualified for continuous service – 100% ED).

This kind of fast opening solenoid valve is normally installed as safety and regulating device in gas trains, for industrial applications and gas firing systems.

 

Description

Elektrogas VML type valve is a slow opening single-stage solenoid valve, normally closed (open whenenergized). This type of device is suitable for air or gas blocking and releasing controls, requiredin gas power bumers, atmospheric gas boilers, industrial kilns and others gas consumingappliances.

Features

The valves are made of aluminum alloy die-cast, with a wide range for inletloutlet connectionsfrom DN10 (3/8") up to DN80 (3").

Sealings are made of NBR-based rubber certified for use with gas (EN 549).

Suitable for use with air and non-aggressive gases included in the 1, 2 and 3 families (EN 437).Special versions suitable for aggressive gases, free of non-ferrous metals and with FPM seals.Pipe connections meet Group 2 and backpressure sealing is compliant with Class A, accordingto EN161 requirements .

The whole range can be provided in Ex-proof execution, for use in Zones 2 and 22, according to2014/34/EU Directive (ATEX).

The valve is open only when energized: if, for any reason, power supply goes down, the valvecloses immediately (intrinsic safe).

Equipped with max. flow rate and start flow rate adjustment.

An incorporated fine mesh filter protects the valve seat and disc as well as downstreamcomponents and prevents dirty contamination (except 6 bar models).

Provided with G1/8 connection to fit a proof of closure switch or a visual indicator.

Provided with 1/4" pressure gauge on two sides in the inlet chamber, to connect manometers,pressure switches, leakage tester or other gas equipments. Flanged models are provided withgauges also in the outlet chamber.

The coils are provided with terminal box or with ISO 4400 plug (optional). Both systems areprovided with suitable cable gland to avoid water and dirty contamination.

All components are designed to withstand any mechanical, chemical and thermal conditionoccurring during typical service. Effective impregnation and surface treatments have been usedto improve mechanical sturdiness, sealing and resistance to corrosion of the components.

Suitable for heavy-duty cycle operation and qualified for continuous service (100% ED).

Valves are 100% tested by computerized testing machineries and are fully warranted.
