Product Benefits

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.

Funnel-shaped lower body

Designed to ensure that residue matter will fall back into the system and be carried away by the main pipe.

Rolling Seal

The rolling seal provides smooth positive opening and closing over a wide range of pressure differentials.
