Automatic Float Ball Exhaust Valve
The Automatic float ball exhaust valve is made using integral casting. Its core float ball linkage mechanism can automatically adjust opening and closing according to the amount of air in the pipeline. When air accumulates in the pipeline, the valve will automatically open to exhaust air. After the air is completely exhausted, the float ball rises to close the valve. No manual monitoring is required throughout the process. It is applied in closed-loop pipelines such as heating systems, central air-conditioning, water circulation systems, boilers, and heat pump pipelines. It can eliminate air blockages, prevent water pump idling, and improve the heat exchange efficiency of the system.

1. What material is the float of the Automatic Exhaust Valve made of?
The floats of our Plumberstar automatic air release valves are mainly made of SS304 or plastic. How to choose the material of the float can be based on the following information:
Stainless steel float: Good density and stability. Enable the air release valve to open and close sensitively, effectively discharging the air in the pipeline. Suitable for environments requiring high temperature and pressure resistance, such as hot water heating systems and steam systems.
Plastic float: Usually used in applications that are cost-sensitive or have specific requirements for chemical resistance. Common plastic float materials include polypropylene (PP), hollow plastic, and rigid foam polyurethane.

2. Do you have experience in manufacturing automatic air release valves for the European market?
Yes, we have over 20 years of experience in exporting automatic exhaust valves to the European market. We have a good understanding of the technical specifications, certification requirements, and market preferences of the European plumbing and HVAC industries, which has enabled our products to have an excellent track record in residential heating and commercial water supply projects in Germany, the United Kingdom, France, Italy, and Northern Europe.
The main compliance aspects of the Automatic Exhaust Valves we manufacture are as follows: Certifications: Compliant with CE, RoHS, and ISO 9001 standards. Design and Materials: Designed in accordance with European standards, our valves use stainless steel or PP floats. They can be applied in central heating systems. Quality Control: The factory conducts strict 100% pressure testing and leakage testing. This ensures that products meet EU performance standards before shipment.
3. Can the Automatic Exhaust Valve provide a factory inspection report and material certificates?
Yes! Plumberstar even provides factory inspection reports and material certificates for automatic air release valves free of charge.
The factory inspection report includes 100% of the test items for the products during the production process. It includes pressure resistance testing, tightness testing, exhaust efficiency testing, and dimensional accuracy inspection. All these tests are conducted in accordance with the ISO 9001 quality management standards and the requirements of the EU CE certification. The quality inspection report will cover the testing of raw materials before production. The testing of each step during the production process, and the final integrity testing before packaging. All these will be recorded in detail to ensure the traceability of quality.
Regarding material certificates, we will issue corresponding certificates based on the materials used in the products (such as PP floats). The certificates include material composition, performance indicators, and compliance with RoHS environmental protection standards.
