FRP Damper Valve

SIIL damper utilizing only high corrosion resistant parts for air movement and controls. Zero-leakage SIIL dampers are fire retatdant, corrosion resistant, and UV protected.

The Zero-leakage SIIL damper blade is operated using a hand-wheel driven worm gear operator. Pneumatic, electric, or chain-wheel type operaors are optional. Long life teflon bearings accessible from the exterior of the damper require minimum maintenance and ensure unrestricted movement of the roating shaft.

Zero-leakage SIIL damper enhance safety by providing greater isolation of process air during shidown of low pressure exhaust system duct lines conveying hazardous air streams. When dealing with confined space entry conditions, use of Zero-leakage SIIL dampers may reduce safety risks caused by contaminant air leaks.

Zero-leakage SIIL dampers require far less maintenance, are more durable, and outperform conventional butterfly dampers.

Zero-leakage SIIL dampers range in sizes from 4-inch diameter to 120-inch diameter.
