Product Benefits
Conical body shape
Designed to maintain the maximum distance between the liquid and the sealing mechanism and still obtain minimum body length.
Independent spring-guided linkage
Allows free movement of the float and rod. Vibrations and movement of the lower float due to turbulence will not unseal the upper float mechanism.
Rolling Seal
The rolling seal is less sensitive to pressure differential & provides smooth positive opening, closing, and leak free sealing. It accomplishes this by having a comparably large orifice for a wide pressure range.
