Advanced Coating for Lasting Protection

This air release valve is protected with a fusion bonded epoxy coating. The advanced coating ensures outstanding resistance to corrosion and chemical attack, making it suitable for potable water, sewage, and industrial pipeline applications. Its superior surface finish enhances durability and prevents build-up, ensuring reliable function even in harsh conditions.

Reliable Sealing and Materials

The valve employs a robust EPDM or NBR elastomeric seal, combined with stainless steel 304/316 float materials. This selection assures longevity, chemical compatibility, and leak-proof performance. The bolted body bonnet joint with a gasketed seal further reinforces the integrity of the valve under variable pressures.

Versatile Applications and Standards

Engineered to meet several international flange standards (IS 1538, ASME, DIN, BS), this valve is ideal for water, sewage, and gas pipelines, as well as varied industrial uses. Its range of connection types and valve sizes ensures compatibility with existing infrastructure and diverse operational requirements.

FAQs of Air Release Valve:

Q: How does the fusion bonded epoxy coating benefit the air release valve?

A: The fusion bonded epoxy coating provides excellent resistance to corrosion, enhancing the valves longevity and performance in both potable and waste water applications. It also prevents scaling and chemical aggression encountered in raw water and sewage environments.

Q: What is the working pressure and burst pressure of this valve?

A: The valve operates efficiently within a pressure range of 0.2 bar to 25 bar. For safety, the burst pressure is designed at a minimum of 1.5 times the maximum working pressure to accommodate sudden surges or system anomalies.

Q: When should a double orifice air release valve be installed in a pipeline system?

A: A double orifice air release valve should be installed where air pockets commonly formtypically at high points or long ascending pipelines. This prevents air accumulation which could disrupt flow or cause water hammer in potable, waste, or raw water systems.

Q: Where can these valves be used?

A: These valves are suitable for water, sewage, and gas pipelines, including industrial and power plant applications. Their robust construction and various flange standards allow for installation across infrastructure in India and internationally.

Q: What is the process for selecting the appropriate valve size and connection type?

A: Valve size (DN25 to DN150) and connection type (flanged or screwed) should be chosen based on pipeline diameter, pressure requirements (PN10, PN16, PN25), and system design. Consulting with the manufacturer or supplier ensures suitability for specific applications.

Q: How does the single chamber, ball-type design facilitate air release?

A: This structure allows for automatic and quick elimination of trapped air. The stainless steel float efficiently detects air accumulation, activating the valve mechanism to discharge air while maintaining system sealing during normal operation.
