Quick-acting slide valve GATEX PRO

Producer: RSBP

The Quick-acting slide valve GATEX PRO is used for active containment of explosions in pipelines. Designed in accordance with the European Directive 2014/34/EU and based on EN 15089 and EN ISO 80079-36, this explosion isolation slide valve belongs to device group II. It is suitable for explosion hazard zones: inside the valve (20,0 – Ga, Da) and outside the valve (22,2 – Gc, Dc).

The Quick-acting slide valve GATEX PRO is a guillotine-type gate valve that operates by continuously monitoring the pressure of the dust/air mixture in the protected pipeline. When an explosion occurs, the pressure rises, and sensors immediately transmit a signal to the CONEX control unit. The controller then sends an electrical impulse to the pneumatic actuator, which ensures rapid closure of the hazardous pipeline section within milliseconds. Thanks to its high response speed, the valve can be installed in close proximity to explosive equipment.

The GATEX gate valve is also designed with fail-safe protection. In case of abnormal operation—such as a pressure drop in the pneumatic circuit below 5 bar, or loss of power supply or control signal—the system automatically switches to slow-closing mode and safely seals the pipeline.

Important. The pneumatically actuated explosion isolation slide valve is intended exclusively for explosion localization. It must not be used as a general shut-off valve for process substances in pipelines.

Advantages

Provides rapid containment of an explosion – in less than 60 ms.
Applicable on pipelines with nominal diameters from 50 to 200.
Resistant to overpressure up to 21 bar.
Can be operated at ambient temperatures from -5°C to 50°C (with heated casing from -30°C, with other special components up to 70°C).
Can be installed in close proximity to explosive equipment, thus greatly reducing the potential area of destruction in an explosion.

The GATEX pneumatic anti-explosion gate valve can be operated in automatic or manual mode.

The main part of the GATEX gate valve: the body, the entire pneumatic part, is made of aluminium alloy. Other components, such as the locking blade, are made of stainless steel.

When the valve is installed outdoors, a heated waterproof cover is used to protect it from adverse climatic conditions.

Installation

The GATEX explosion isolation slide gate valve is delivered fully assembled and includes all necessary components: pressure sensors, the CONEX control centre, and the CONEX-IVM valve control unit.

Before installing the rapid-acting slide valve, it is important to check the integrity of the original packaging, as well as the surfaces of all parts and flange gaskets. In case of any defects, the dealer or manufacturer must be contacted immediately.

The explosion-proof quick opening valve must only be mounted on the pipeline by qualified personnel. Each unit is supplied with detailed instructions and drawings, but as it is a safety-critical device, strict adherence to guidelines is required.

Correct installation distance is crucial: if the valve is mounted too close, the explosion will not be localized and can propagate through the pipeline. If mounted too far, the valve may collapse due to overpressure from the shockwave.

The delivery package includes:

commissioning protocol;
an act of handover;
an installation document;
functional test certificate;
a record of staff training;
EC Declaration of Conformity according to 2014/34/EU;
GatEx gate valve system checklist;
maintenance and repair log;
CONEx control centre manual;
CONEX IVM control centre manual;
manual for the DetEx pressure transmitter.

On request we will provide a drawing of the connecting flanges and wiring diagram of the solenoid valves.

Maintenance

The operator must appoint a responsible person for the safe use and maintenance of the GATEX explosion isolation slide gate valve. In addition, a maintenance manual must be prepared according to the manufacturer’s instructions.

Service intervals depend on operating conditions, for example the level of dust accumulation in the pipeline. Recommended checks are performed two weeks after commissioning, and then approximately once a month.

Maintenance tasks include regular inspections for mechanical wear or clogging of the cleaning chamber. Only trained personnel are allowed to perform these operations.

All service activities must be recorded in the official maintenance and repair log supplied with the valve.

The standard service interval for the GATEX rapid-acting slide valve is 6 months, ensuring long-term reliability and compliance with safety standards.
