Описание продукта

This threaded brass air admittance valve is designed to help maintain pressure balance in water pipeline systems. When pipeline pressure drops, the valve opens to admit air into the pipe and closes again after the pressure stabilizes, helping support safe and steady system operation.

Key Features

One-way mechanical valve for pipeline pressure balancing
Allows air to enter the pipe when internal pressure decreases
Closes automatically after pressure balance is restored
Brass body construction suitable for water pipeline applications
Vertical installation design for proper valve operation
Threaded connection options for different project requirements
Available with BSPP (G), BSPT, or NPT threads
PN16 pressure rating for standard pipeline use
Compact size range from DN15 to DN50
