Description
These double union PVC ball valves have excellent corrosion-resistant characteristics and can be dismantled for maintenance and inspection purposes.
Pressure Rating
PVC ball valves up to 1 1/2" (50mm) have a pressure rating of 15 bar (215 psi) at 20oC.
2" to 4" (63mm to 110mm) PVC ball valves have a pressure rating of 10 bar (159 psi) at 20oC.
As temperature increases the pressure rating is reduced. PVC systems should not be used where temperatures exceed 60oC.
