วาล์วอากาศรวมสำหรับน้ำเสียและน้ำทิ้ง พร้อมระบบป้องกันแรงดันกระแทก ผลิตจากสแตนเลสและไนลอน GR PN16 / 230 PSI

• Straight flow body: Higher than usual flow rates.

• Elongated body design: Prevents solids from making contact with valve’s operating parts.

• Surge Protection: the kinetic orifice is partially closed during the second stage of the air relief, preventing damage to the air valve and the system and increasing the operational time without maintenance.

• Dynamic Sealing: Prevents leakage under low pressure conditions (0.8 psi; 0.05 bar).

• Two service ports: Upper 3/4"; DN20 NPT and lower 1"; DN25 NPT, enabling back flushing and drainage.

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

• Certified to functional standards: SAI AS4883 (Australia).

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