Elektrogas Brand VMR Model Safety Solenoid Valves For Air And Gas

VMR VMR60

Safety solenoid valves for air and gas, fast opening and fast closing type

The Italy Elektrogas VMR type valve is a fast opening solenoid valve that is normally closed.

When the coil is not energized the spring works on the disc keeping the gas passage closed. When the coil is powered the valve opens. 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). Suitable for high-frequency switching systems.

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

The VMR type valve is a fast opening single-stage solenoid valve, normally closed (open when energized). This type of device is suitable for air or gas blocking and releasing controls, required in gas power burners, atmospheric gas boilers, industrial kilns and others gas consuming appliances.

Ambient temperature: -15°C to +60°C

 

Features

Elektrogas Solenoid Valves are made of aluminum alloy die-cast (or hot-pressed brass for OTN versions), with a wide range for inlet/outlet connections from DN 8 (1/4”) up to DN 150 (6”).

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, according to EN161 requirements.

The whole range can be provided in Ex-proof execution, for use in Zones 2 and 22, according to 2014/34/EU Directive (ATEX).

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

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

Equipped with flow rate adjustment (except brass models).

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

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 (except brass models), to

connect manometers, pressure switches, leakage detectors or other gas equipments. Flanged models are provided with gauges also in the outlet chamber.

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

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

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