Description
The presence of air in a sewage system can reduce the effectivecross sectional flow area resulting in increased pressure loss and deceased flow.
Unwanted air may also cause water hammer and metering inaccuracies, while hastening corrosion.

Main Features
• Conical body shape maintains maximum air gap, and spring loaded float and seal plug connection, combine to ensure no contact between the sewage and the seal.
• Funnel shaped lower body automatically drains sewage into the system, allowing valve internals to remain clean and unobstructed.
• Rolling, resilient seal, provides smooth positive opening, closing, and leak free sealing, over a wide range of pressure differentials.
• Internal metal parts are made of corrosion resistant stainless steel. Body drain with ball valve is provided.
• 250 psi working pressure. Tested to 350 psi.
• Standard fusion bonded coated valve body. Other coatings are available.

Ordering
Upon ordering, please specify: model, size, working pressure, threads/flanges standard and type of liquid.
