TLX Technologies is pleased to announce that our Explosion Proof Actuator with Supervision has recently completed all testing to meet UL HazLoc, ATEX, and IECEx certifications for use in fire suppression systems in hazardous locations (a certificate of conformity is available upon request).
Fire suppression systems that rely on a combination of pneumatic and electric actuators suffer from multiple potential leak points due to the number of connections required to route discharge pressure through the system. The patented Explosion Proof Actuator with Supervision provides an effective solution. Uniquely designed as a top-mounted linear actuator, it does not act as a pressure vessel on the discharge valve. As a result, the only potential leak point in the system is inside the top of the discharge valve at the discharge valve pin.
Specific design features and material grade selection allow the actuator to act as its own enclosure. This eliminates the need for additional components and simplifies the system. All potential flame paths are specifically designed to prevent flame egress in the event a spark were to ignite any gas found within the actuator.
The actuator’s force output can be modified to accommodate any system’s operating pressure up to 300 bar. This allows the actuator to effectively open the valve without damage to the system.
All linear actuators designed and produced by TLX Technologies for the fire suppression market meet NFPA 2001: Sec. 4.3.4.1 standards for supervision. The integrated supervisory feature provides fully-engaged installation detection to indicate that the actuator has been correctly installed or disconnected from the system.
