[Valve features]
       That is, continuous and intermittent discharge of saturated condensed water, heating equipment will not have the accumulation of water, so as to achieve the highest thermal efficiency.
      The water resistant knockdown bucket structure is not damaged by water hammer and has long service life.
The utility model has the advantages of good air exhaust performance, and the overflow bucket is provided with overflow exhaust holes, which can effectively prevent steam air lock and air air blocking.

Allowing high back pressure, back pressure rate of 85%.

Convenient maintenance, internal parts made of stainless steel, are installed on the valve cover, and equipped with filter screen device, daily maintenance convenience.



[Adaptive condition]
       Used in petroleum, chemical, power, textile, printing and dyeing, medical, pharmaceutical and other industries steam heating equipment, steam pipe network and low superheated steam conditions. It can quickly remove condensate and effectively prevent steam leakage.
