Working Principle:
● Relies on the density difference between gas and liquid.

Product Features:
● Valve body and cover are made of cast steel or forged steel.
● Internal parts are all made of stainless steel with wear-resistant allowances to extend the service life of the drain valve.
● Special flow channel design eliminates water hammer phenomena.
● Dual assurance of no gas leakage and long service life through patented flexible closing system and micron-level precision closing system.
● Pressure equalization balance pipe completely solves air locking issues.
● Independent filter ensures the air trap works in a clean environment.
● Different displacement curves can be selected according to pressure differences to increase capacity.
● The bottom of the air trap is designed with a blowdown plug to ensure internal water is drained after shutdown, preventing the float ball from freezing.
