Protect your irrigation and water distribution systems with the AUTOMAT Air Release Valve Aluminium HT-89 F-THD. Made from lightweight yet durable aluminium, this 1.5-inch (50 mm) valve automatically expels trapped air and provides vacuum relief, preventing dangerous air pockets and pipe damage.
Its Female Threaded (F-THD) connection ensures quick installation, while the simple, reliable design works efficiently at operating pressures from 0.5 to 10 bar. Suitable for drip irrigation, overhead pipelines, or any setup where air removal is vital.
Choose AUTOMAT—trusted for robust, corrosion-resistant valves that keep your pipelines safe, efficient, and hammer-free.
The AUTOMAT Air Release Valve Aluminium HT-89 F-THD is widely used in:
- Agricultural drip irrigation systems
- Overhead sprinkler lines
- Water distribution pipelines
- Industrial water networks
- Any pipeline where trapped air and vacuum relief is a risk
AUTOMAT Air Release Valve Aluminium HT-89 F-THD FAQs:
Q1: What is the purpose of the AUTOMAT Air Release Valve HT-89 F-THD?
A: This air release valve automatically expels trapped air from your pipelines and provides vacuum relief when needed. It prevents air locks, water hammer, and pipe bursts in irrigation or water supply systems.
Q2: Where should I install the HT-89 Air Release Valve?
A: Install the valve at the highest points in your pipeline where air naturally collects. It’s ideal for drip irrigation lines, overhead sprinklers, and main pipelines.
Q3: How does the aluminium body help?
A: The cast aluminium body makes the valve lightweight, durable, and resistant to corrosion—giving it a longer lifespan than standard plastic valves.
Q4: What does F-THD mean?
A: F-THD stands for female threaded end connection. This makes installation quick and compatible with standard threaded fittings.
Q5: Can it handle high-pressure pipelines?
A: Yes, the HT-89 works effectively at pressures from 0.5 up to 10 bar, making it suitable for high-flow irrigation or industrial water lines.
Q6: Does it help prevent water hammer?
A: Absolutely. By automatically expelling trapped air, the valve prevents sudden pressure surges (water hammer) that could damage your pipes or fittings.
Products to complement AUTOMAT Air Release Valve Aluminium HT-89 F-THD:
- Pair with AUTOMAT Non-Return Valves for complete pipeline protection
- Combine with AUTOMAT Pressure Relief Valves for high-pressure setups
- Use with AUTOMAT Filters and AUTOMAT connectors
