    Frequently Asked Questions
    What is a Compound Exhaust Valve and what is it used for?
    A Compound Exhaust Valve, also known as a Combination Air Valve, is designed to remove large amounts of air accumulated in pipelines and discharge small amounts of air collected at higher points. It is commonly installed at pumping outlets or in water distribution pipelines.
    What materials are used in the construction of this valve?
    Key components such as the screen cover, screen, retainer, float ball, guide pin, leverage bracket, air-vent, and connection tube are made of Stainless Steel. The body, cover, and gasket are made of Ductile Iron, while sealing and cushion parts use NBR or EPDM rubber materials.
    Does the Compound Exhaust Valve require manual operation?
    No. The valve features automatic air releasing and filling, which means it operates without any manual intervention, making it highly convenient for continuous pipeline systems.
    What pressure ratings are available for this valve?
    The valve is available in two pressure ratings: PN10 and PN16. Both ratings are offered across a range of nominal diameters (DN) from DN50 to DN300, with corresponding flange dimensions provided in the specification table.
    What sizes (DN) are available for this Compound Exhaust Valve?
    The valve is available in the following nominal diameters: DN50, DN80, DN100, DN150, DN200, DN250, and DN300, covering a wide range of pipeline installation requirements.
    Is the Compound Exhaust Valve easy to install and maintain?
    Yes. The valve features a simple structure that makes installation straightforward. Its durable, long-lasting construction and reliable sealing design also minimize the need for frequent maintenance, reducing overall operational costs.
