Safety Related Applications

Wheter looking for a SIL certified pilot valve, a redundant control system cabinet or a solenoid valvbe for use in High Integrity Protection System, ASCO have the solution. Certified to SIL level 3 and with extreamly high mean time to failure (MTBF) you can be assured that safety related solutions will protect your plant for years to come.

ASCO Hazardous Area Solenoid Valve Operators

ASCO have operator solutions to meet a wide range of hazardous area directives including ATEX, IEXEx, GOST and more. Flameproof, explosion proof, intrinsically safe solenoid valve operators are available.

ATEX, IECEx Hazardous Area Solenoid Valve Operators

Ex i Intrinsic Safety - ASCO ATEX & IECEx Solenoid Valve Operators

A protection concept in which the electrical energy within the equipment is restricted to a level which is below that what may cause an ignition or to limit the heating of the surface of the equipment.

There are two main sub types to Ex i protection, these being “ia” and “ib”. Type “ia” protection allows for the occurrence of two faults during operation Type “ib” protection allows for the occurrence of one fault during operation.

Ex d Flameproof - ASCO ATEX & IECEx Solenoid Valve Operators

The equipment that may cause an explosion is contained within an enclosure which can withstand the force of an explosion and prevent transmission to the outside hazardous atmosphere.

This method of protection also prevents the hazardous atmosphere from entering the enclosure and coming into contact with equipment.

Ex m Encapsulation - ASCO ATEX & IECEx Solenoid Valve Operators

A protection concept where by equipment that could potentially cause an ignition is encapsulated within a compound or resin so as to prevent contact with the explosive atmosphere.

The concept also limits the surface temperature of the equipment under normal operating conditions.

Ex e Increased Safety - ASCO ATEX & IECEx Solenoid Valve Operators

Precautions are applied to the installation to ensure increased security against the possibility of excessive temperatures and sparks from electrical equipment.

Equipment that normally causes sparks is excluded from use within this method of protection.

NEMA 7 - ASCO Solenoid Valve Operators

Enclosures are for indoor use in locations classified as Class I, Groups A, B, C, or D and shall be capable of withstanding the pressures resulting from an internal explosion of specified gases, and contain such an explosion sufficiently that an explosive gas-air mixture existing in the atmosphere surrounding the enclosure will not be ignited.

Enclosed heat generating devices shall not cause external surfaces to reach temperatures capable of igniting explosive gas-air mixtures in the surrounding atmosphere.

Enclosures shall meet explosion, hydro-static, and temperature design tests.

NEMA 9 – ASCO Solenoid Valve Operators

Enclosures are intended for indoor use in locations classified as Class II, Groups E, F, or G, and shall be capable of preventing the entrance of dust.

Enclosed heat generating devices shall not cause external surfaces to reach temperatures capable of igniting or discolouring dust on the enclosure or igniting dust-air mixtures in the surrounding atmosphere.

Enclosures shall meet dust penetration and temperature design tests, and aging of gaskets (if used).
