วาล์วอากาศแบบผสมพร้อมระบบป้องกันแรงดันกระแทก ซูเปอร์ดูเพล็กซ์

• 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.
