Double Ball Air Valve Type-A PN10/PN16

Description

The Double Ball Air Valve (Type-A) is a highly efficient combination air release valve designed to maintain pipeline integrity. It automatically performs three functions: releasing large volumes of air during pipeline filling, discharging small pockets of air during pressurized operation, and admitting air into the system during drainage to prevent vacuum collapse. This "Triple Acting" performance makes it a critical safeguard for municipal and industrial water networks.

Technical Specifications

• Design Type: Double Orifice (Combination) / Type-A

• Pressure Rating: PN10 / PN16

• Body Material: High-strength Ductile Iron (GGG40/50)

• Internal Floats: Stainless Steel (AISI 316) for corrosion-free performance
