ARI D-050-C Combination Air Vacuum Valve

Description

A.R.I. D-050 is a reduced bore Combination Air Valve Series. Installed on liquid transmission systems, the Air Valve is designed to improve hydraulic operation by protecting the pipeline, increasing pipeline efficiency and reducing energy requirements.

Benifits

• Easy to install and maintain, reduces downtime
• High-capacity air discharge, no premature closure
• Reduces water hammer impact
• Saves energy and increases system efficiency
• Long-term maintenance-free operation
• Screen protected outlet that prevents intrusion of insects and debris
• Non-corrosive and durable
• Leak-free sealing over a wide range of pressure differentials
• Automatic air release valve orifice that allows for high flow air release, lessens obstruction by debris

Installation Guidline

• Pump stations: downstream of the pump and the check valve
• Downstream and upstream of shut-off valves
• Downstream of deep-well pumps
• On long constant-sloped pipeline segments
• At peaks along the pipeline and at peaks relative to hydraulic gradient
• At end lines
• Before water meters
• On strainers and filters
• Municipal and industrial water conveyance systems

• 0.2 – 16 bar
• Maximum working temperature: 60° C
• Maximum intermittent temperature: 90° C
• Connection type: Threaded male BSPT(2″)
