วาล์วระบายอากาศแบบผสม เหล็กหล่อเหนียว

• Straight flow body with nominal (equal) inlet and outlet size: Higher than usual flow rates.

• Dynamic sealing: Prevents leakage under low pressure conditions (3.0 psi; 0.2 bar).

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

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

• Designed in compliance with functional standards and water service standards.

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

การใช้งานทั่วไป

• Pumping stations and deep well pumps: Air relief, surge protection and vacuum prevention.
• Pipelines: Protection against air accumulation and vacuum formation at elevations, slope change points and road / river crossings.
• Water networks: Protection against vacuum formation, surge and water hammers at points likely to experience water column separation.
