Vent valves
Vent valves are essential components in heating and plumbing systems, ensuring the efficient removal of air and moisture. This category includes automatic and manual vent valves designed for use in central heating systems, irrigation, and sanitary applications. Products range from compact 3/8" models to larger 1" corner valves, with options featuring non-return valves, stop valves, or hygroscopic functions for specific system requirements.
These valves help prevent issues such as reduced system efficiency, corrosion, and uneven heat distribution caused by trapped air. They are commonly used in radiators, expansion tanks, and circulation loops to maintain optimal performance.
How to choose
- Choose the correct connection size (e.g., 1/2", 3/8", or 1") based on the pipe or fitting dimensions in your system.
- Ensure compatibility with the system type (central heating, irrigation, or sanitary) and select a model with the appropriate function (e.g., automatic, manual, or with a non-return valve).
- Consider the material (e.g., brass or nickel-plated) for durability and resistance to corrosion in wet or high-temperature environments.
Frequently asked questions
Can a manual vent valve replace an automatic one?
Manual vent valves require periodic opening to release air and are not suitable for systems requiring continuous or unattended air removal. Automatic models are preferred for central heating systems.
What is the purpose of a non-return valve in a vent valve?
A non-return valve prevents backflow of water or steam into the system after air has been released, ensuring the system remains sealed and operational.
