The main parameters

A, reverse leakage: pass into the 1.0MPa compressed air, the amount of leakageis less than or equal to 500ml/min.

B, air tightness: pass into the 3.0MPa compressed air, into the water, no air bubbles.

C, life: on the test bench, with compressed air pressure 1.0MPa continuous open / closed after the 100000 time, the valve core moves flexible, have no card, card dead phenomenon, leakage is less than or equal to 750ml/min.

D, the use of temperature: the temperature of -30 DEG C and 120 C. The main advantage of one-way valve body structure adopts stainless steel taper valve core, low leakage, the valve opening and closing are flexible, conducive to therapid flow of fluid.
