2. Size: 2½" - 6''; 75mm - 160mm ; DN65 - DN150
3. Standard: ANSI, DIN, JIS, CNS
4. Joint End: Socket or Threaded(NPT,PT,BSPF)
5. Working Pressure: 150 PSI
6. Operating Temperature: PVC(0~55℃); CPVC(0~95℃)
7. Valve body color : PVC(dark gray), CPVC(light gray)

ADVANTAGES : 

1. Materials meet drinking water standard
2. 100% pure virgin material, CaCO3 free (Chalk)
3. UV resistant powder added
4. Can be assembled vertically or horizontally

1. In particular increase the thickness at the end of body for impact resistance strength when suddenly open.
2. Two plane and the Oring grooves are by machining, to ensure the combination of surface formation, better sealing.
3. Improved design on valve rib, at the bottom to reduce weight and greatly increased due to water hammer valve imp act resistance and strenght.
4. The abolition of the metal shaft, all to switch to all-in-one plastic structure, increased corrosion resistance.
5. Buckle fixed valve petal, the elimination of the original way, replacing the two columns of fixed processing erros, and increase the opening angle to reduce the flow resistance.
6. Sealing surface design is titled 10 degrees, so that it also can use at the level of the installation.
7. Lock 8 screws the upper and lower body more closely and firmly, under the water hammer, it is diffcult deformation, better sealing.
