Product Benefits
Long body shape
The longer body builds an air gap that separates the liquids with suspended particles from the sealing mechanism.
Dynamic Design
The dynamic design allows for high capacity air discharge while also preventing premature closure.
Rolling Seal Mechanism
The Rolling seal mechanism design is less sensitive to different pressures than a direct float seal, thus enabling a one size orifice for a wide pressure range (up to 16 bar).
