วาล์วระบายอากาศแบบผสม เหล็กหล่อเหนียว

• Straight flow body: Higher than usual flow rates.

• Dynamic Sealing: Prevents leakage under low pressure conditions (1.5 psi; 0.1 bar).

• Minimizes water spraying during air release: Innovative 2-step function, automatic orifice (Patented).

• Three optional outlets (sideways, downwards, circular surround mushroom configuration) that can swivel 360°: Easy to install in a variety of site conditions.

• Compact, simple and robust structure with fully corrosion resistant internal parts: Lower maintenance and increased life span.

• Certified to functional standards: AENOR (Spain).

• Certified to drinking water standards: NSF/ANSI/CAN 61 and NSF/ANSI 372 (USA).

• Factory approval and Quality Control: Performance and specification tested and measured with specialized test bench, including vacuum pressure conditions.

การใช้งานทั่วไป
