Features:
 
1. AWWA butterfly valves completely conform to standard AWWA C504 and AWWA C516, suitable for water system, connection types include wafer, flanged and mechanical joint end
 
2. Valves have passed cycle life test of standard AWWA C504, during the complete cycle test, bi-directional tightness is reached under the different pressure drops, valves provide reliable performance in the whole service life
 
3. NPS 30 (DN750) and larger size valves use triple-eccentric design with low torque, compact structure, easy to install, body sealing rings and seat sealing rings can be replaced on site
 
4. To NPS 30 (DN750) and larger size valves, body and disc can be casting or welding, made of carbon steel or stainless steel
 
5. Valves are certified by NSF, surface coating is non-toxic high-solid epoxy resin, all metal parts contacting with fluid are stainless steel
 
6. Valves are in complete conformity to the standard AWWA C504, reliable performance, long service life with shock-resistance and high-security
 
 
Applications:
 
AWWA C504 butterfly valves are chiefly applied to the water industry:
 
1.    Drinking water pumping station for water transportation and distribution
 
2.    Seawater desalting plant
 
3.    Urban water supply and drainage, water conservancy, water treatment
 
4.    Cold water circulation system (in plant and power station)
 
5.    Other water circulation system
