ATEX/IECEx Certified MDF Kit Valve Activator for Explosive Dust Environments with Intrinsic Safety Protections
Product Description :
Operate with absolute confidence in hazardous zones using our ATEX/IECEx Certified MDF Kit Valve Activator – the only intrinsically safe solution for MDF mills handling
combustible dusts. This explosion-proof valve operator carries global certifications (ATEX Cat. 1D, IECEx, NEC 500 Class
II Div 1) for environments with Kst >200 bar·m/s dust
explosibility. The patented anti-static actuator features graphite-free composites, earth-bonded shafts, and
energy-limiting circuits preventing ignition sparks even during
component failure. Dual independent failsafes force valves closed
during pressure/temperature excursions, while hermetically sealed
sensors monitor for smoldering particle accumulation. Constructed
with non-sparking bronze alloys and static-dissipative polymers,
this hazardous-area controller maintains precise resin flow control at 180°C ambient
temperatures. Includes self-testing ground continuity monitoring
and automatic lockout during safety system faults. Essential for
plants processing fire-prone woods or using solvent-based adhesives
where standard actuators pose explosion risks.
Bullet Points:
Globally certified MDF Kit Valve Activator (ATEX/IECEx/NEC)
Explosion-proof valve operator with <5μJ ignition energy prevention
Continuous ground monitoring with auto-shutdown
Non-sparking construction (CuAl10Fe bronze alloys)
180°C operating temperature rating
Specific Application Scenario:
Controlling solvent-based PUR adhesive valves in sanding dust
collection zones with documented combustible dust hazards.
FAQ:
Q: What dust explosibility classes does this anti-static actuator
cover?
A: Certified for St1/St2/St3 dusts with Kst ≤300 bar·m/s (e.g.,
wood, phenolic resins).
Q: Maintenance requirements in explosive atmospheres?
A: Zero-spark tool kit provided; field service requires Hot Work
Permit waiver.
Q: Can the hazardous-area controller interface with safe-area PLCs?
A: Yes – fiber-optic isolated signals with Zener barrier options.
Q: Response time during emergency power loss?
A: 0.8 second full closure via spring-fail mechanism.
Q: Certification renewal process?
A: 5-year recertification included with extended service contract.
