A rotary valve, which is commonly referred to as a “star” valve, is rotating piece of equipment with vanes (pockets) that discharges dust into a drum or pneumatic conveying system. All rotary valves require a TEFC motor, gearbox and drive. Rotary valves are high torque devices and can be dangerous for operators and maintenance personnel if not properly protected with finger guards

NFPA 68,69 and 652 are standards that define the requirements for explosion protection and compliance as it relates to combustible dusts.  

The XP Drum Kit and testing report satisfies the following equivalency statement found in NFPA 69, Standard on Explosion Prevention Systems:

• NFPA 69 Standard allows the use of systems, methods, or devices of equivalent or superior quality, strength, fire resistance, effectiveness, durability, and safety over those prescribed in this standard.
• Technical documentation shall be submitted to the authority having jurisdiction (AHJ) to demonstrate equivalency.
• The system, method, or device shall be approved for the intended purpose by the AHJ

Yes, the XP Products Drum Kit satisfies NFPA 69 equivalency statement….. use of systems, methods, or devices of equivalent or superior quality, strength, fire resistance, effectiveness, durability, and safety over those prescribed in this standard.

Yes, the XP Products Drum kit is a pressure rated extension of the dust collector with tested pressure rating 0.9 bar.  The XP Products Drum Kit allows a larger cross sectional area to prevent product build up and bridging in the discharge hopper opening.

Yes, since the XP Products Drum Kit has not rotating parts the operator is not exposed to finger injuries or pinch points. OSHA (Chicago) has stated that the XP Products Drum Kit is safer than a rotary valve. The XP Drum Lift Cart allows operators to roll the drum in/out without operator interface, reducing back and hand injuries.

Yes, as long as XP Products receives the hopper outlet flange dimensions and overall height from flange to floor. There are over 800 XP Products Drum Kit installations across North America on (22) different Dust Collector manufacturer types.
