The Brass Air Vent Valve for heating and chilled systems is an automatic air vent valve that allows your system to function more efficiently. It opens and closes as needed to allow the free flow of air, which prevents pressure build-up and eliminates the need for manual ventilation. This saves you time and hassle while ensuring that your system runs smoothly. This valve is made from brass for durability and is perfect for heating or chilled systems.

This brass air vent valve is perfect for automatically regulating the airflow in heating and chilled systems. It is made from durable brass and has a robust design that can handle high-pressure and temperature fluctuations. The automatic operation makes it easy to use, and the compact size means it can be installed in tight spaces. This valve is ideal for use in residential or commercial applications.

The brass air vent valve for heating and chilled systems is a self-acting automatic air vent that allows free air circulation when required. It is suitable for use on heating or chilled systems with a working pressure of up to 10 bar (145 psi) and a temperature range of -10°C to +100°C (-14°F to +212°F). The valve incorporates a manual override which can be used to hold the valve open or closed as required.

The brass air vent valve for heating and chilled systems is supplied with an adjustable mounting bracket, allowing it to be fitted in any orientation.

Works: Automatic air vent valves are designed to release the air trapped in heating and cooling systems. When water is heated, it can release air bubbles that can become trapped in the system and reduce efficiency. The automatic air vent valve allows these air bubbles to be removed automatically, which helps to keep the system working at its optimal level.

Applications: Automatic air vent valves are commonly used in heating and cooling systems, such as boilers, radiators, and HVAC systems. They are also used in irrigation systems, where air can become trapped in the pipes and reduce water flow to the plants.

Installations: Automatic air vent valves are installed at high points in the system where the air is likely to become trapped. They are typically installed vertically, with the valve at the highest point. Installation requires cutting into the pipe and fitting the valve with the appropriate connection, either threaded or soldered.

Raw materials: Automatic air vent valves are typically made of brass, bronze, or stainless steel, durable and resistant to corrosion. The float and valve mechanisms are often made of plastic or lightweight materials resistant to chemicals and temperature changes.

Sizes: Automatic air vent valves come in various sizes to fit different pipes and systems. They can range from 1/8 inch to 2 inches, with larger sizes available for commercial and industrial applications. It is important to choose the appropriate size for the system to ensure proper function.

Frequently Asked Questions

Here are typical questions by customers asked with usual, please feel free contact us if any further confused.

Brass valves have many different types, such as ball valves, garden tap, check valve, strainer, angle valve, gate valve, foot valve, and drain valve. The radiator valve and thermostatic mixing valve are works for water temperature. All of these valves are work for water plumbing systems, plumbing repair, and installation. So have to let water shut-off and shut-on. Some heating systems are related to hot water and cold water mixing for temperature control and stability. Our intelligent valves are functional. There are applications in commercial, residential, and industrial areas.

Underfloor heating radiant pex manifolds are usual for residential water distribution in a household, and it's top-rated in the home building industry. Manifold plumbing systems control hot and cold water that feeds flexible PEX supply lines to individual fixtures. Then water temperature is warm and stable in each room. Meanwhile, the heating accessories-flow meter gauge will monitor water and temperature in each room.

The motorized ball valve works automatically open and closed; they work with 220v-230v AC and 24v DC; they are applications in the heating system, air conditioner,3D printer, and others. The solenoid valve is with similar features.
