Van kết hợp xả khí với chức năng bảo vệ chống sốc áp

• Straight flow body with nominal (equal) inlet and outlet size.
• 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.
• Compact and simple structure with fully corrosion resistant internal parts: Lower maintenance and increased life span.
• Factory approval and Quality Control: Performance and specification tested and measured with specialized test bench, including vacuum pressure conditions.
