Performance characteristics
» It can eliminate the gas in the pipeline, reduce resistance and save paper and energy.
» When the pipeline is under negative pressure, the double port exhaust valve can automatically suck in air to prevent pipeline rupture.
» The floating ball is made of stainless steel, with long service life, safety and reliability.

Technical parameters 
» Medium: clean water
» Medium temperature: normal temperature
» Shell temperature and test pressure: 1.5MPa
» Floating ball sealing test pressure: 0.05 ~ 1.1MPa
» Valve body material: gray cast iron HT200
» Floating material: stainless steel
» Flange connection standard: GB / t12741.6-98
» Pressure test standard: Q / yfc01-2003

Installation instructions
» The double orifice air valve shall be installed vertically, and a protective valve (butterfly valve and gate valve) must be installed under it to avoid water failure during inspection.
» If the size of the exhaust valve flange is changed by the demander, please indicate the flange connection size.
