| Valve Type: | Exhaust valve | Structure: | Compound |
| Standard: | BS/API/DIN/JIS | Workmanship: | Investment casting |
| Sealing direction: | Single-directional | Sealing grade: | Zero leakage |
| Temperature: | -20°C < T < 120°C | Operation: | Self-starting |
The composite air release valve is equipped with high-precision floating balls and durable sealing components, achieving tight, leak-proof performance across a wide pressure range. It automatically inhales air rapidly under negative pressure to prevent pipeline vacuum collapse and water hammer risks.

Standard export wooden case packaging is used to ensure the safety of the valves during international transit.
The compound air valve is ideal for municipal water supply, water regulation, and industrial cooling systems. It enhances system stability, lowers energy consumption, and ensures safe operation by effectively controlling air inside pipelines.
A: It automatically releases air during pipeline filling, exhausts air during operation, and rapidly inhales air under negative pressure to prevent vacuum collapse and water hammer.
A: The floating balls are made of high-precision stainless steel to ensure durability, corrosion resistance, and reliable buoyancy.
A: Yes, this valve is designed to operate within a temperature range of -20°C to 120°C.
A: No, the valve is self-starting and operates automatically based on the principle of buoyancy and pipeline pressure changes.
A: It is compatible with multiple standards including BS, API, DIN, and JIS, and supports nominal pressures from PN10 to PN25.
A: It is suitable for various non-corrosive media such as clean water, municipal water supply, and industrial circulating water.
