Description

Heavy-duty 304 stainless steel water hammer arrestor designed to absorb pressure surges and protect pipeline systems from damaging shock waves in water applications up to 12 Bar.


Key Features

Type: I-Style Anti Water Hammer Valve (AIF)
Sizes: DN80, DN100, DN125, DN150, DN200, DN250, DN300
Flange Standard: PN16 (optional JIS10K or ANSI 150lb)
Body Material: 304 Stainless Steel
Working Pressure: 0–12 Bar
Test Pressure: 32 Bar
Air Chamber Volume: 2,465cc to 67,860cc (size dependent)
Pre-Charge Pressure: 2.5 Bar (adjustable via Schrader valve)
Pressure Gauge: Included
Mounting Position: Vertical, horizontal or inverted

Materials & Construction

Body: 304 Stainless Steel
Diaphragm: NBR standard (EPDM optional)
Air Chamber: Sealed pressurised design
Temperature Range: -5°C to +80°C
Media: Water
The stainless steel construction provides improved corrosion resistance compared to ductile iron models, making this version suitable for aggressive water conditions, coastal environments and hygienic installations.

Performance & Design

Instant Surge Absorption: Flexible diaphragm backed by pressurised air chamber eliminates response lag
No Sliding Pistons: No friction wear or mechanical sticking
No Air Bubble Migration: Sealed chamber prevents air loss into pipeline
Long Service Life: Stable damping performance without internal wear components
Patent Protected: Patent No. 140580
Unlike spring or piston-type surge arrestors, the AIF stainless model operates on a diaphragm air-cushion principle, delivering rapid and consistent compensation for sudden pressure spikes.

Where Water Hammer Occurs

Water hammer commonly develops:
Downstream of check (non-return) valves
In horizontal pipelines exceeding 50 metres
During pump start-up or sudden shutdown
In fast-closing valve systems
Installing the AIF stainless steel series in-line significantly reduces shock waves, vibration, pipe stress and the damaging banging effects caused by sudden changes in water velocity.

Applications

Foos production water systems
Pump stations
Industrial process water
Irrigation networks
Fire protection systems
Coastal or corrosive environments
