Hartz alloy butterfly check valve in the domestic product is energy-saving new products. It check good, safe, reliable, small flow resistance, mainly used in chemical, food, medicine, textile, papermaking, energy system used as a check valve, etc. Shanghai Asia work valve manufacturing co., LTD. Production of hartz alloy butterfly check valve in wet chlorine and aqueous solution containing chlorine, has good corrosion resistance. Its outstanding characteristic is in strong oxidizing and reducing mixed acid corrosion medium has excellent corrosion resistance.

Hartz alloy butterfly check valve features:

(1) small volume, light weight, compact structure, easy maintenance.

(2) the valve plate adopts the design of the dual plate add two torsion spring, can make the quick closing valve plate themselves.

(3) because of the quick closing function, can prevent the backflow medium, eliminate water hammer effect is strong.

(4) the body length size structure, good rigidity, easy installation.

(5) to achieve completely sealed, water pressure test of zero leakage.
