What is an aluminum bronze valve

The aluminum bronze valve adopts a top-mounted structure, which reduces the connecting bolts of the valve body under the conditions of high pressure and large diameter, enhances the reliability of the valve and can overcome the influence of the weight of the system on the normal operation of the valve.

The working principle of aluminum bronze gate valve

The opening and closing part of the aluminum bronze gate valve is the gate, and the movement direction of the gate is perpendicular to the direction of the fluid. The aluminum bronze gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used model gate valve form a wedge. The wedge angle varies with valve parameters, usually 5°, and 2°52' when the medium temperature is not high. The gate of the wedge-type aluminum bronze gate valve can be made into a whole, called a rigid gate; it can also be made into a gate that can produce slight deformation to improve its manufacturability and compensate for the deviation of the sealing surface angle during the processing. This kind of gate is called an elastic gate. When the aluminum bronze gate valve is closed, the sealing surface can only rely on the medium pressure to seal, that is, rely on the medium pressure to press the sealing surface of the gate to the valve seat on the other side to ensure the sealing of the sealing surface, which is self-sealing.

Features of aluminum bronze gate valve

The aluminum bronze gate valve is made of high-grade nodular cast iron, and its weight is about 20%~30% lighter than the traditional aluminum bronze gate valve. It is easy to install and maintain. The gate adopts high-quality rubber for the overall inner and outer rubber. The European first-class rubber vulcanization technology enables the vulcanized gate to ensure accurate geometric dimensions, and the rubber and the ductile cast gate are firmly connected, not easy to fall off, and have good elastic memory. The aluminum bronze gate valve body is made of precision casting, and the precise geometric dimensions make the inside of the valve body without any fine processing to ensure the sealing of the valve.

Suitable for low temperature environment

the temperature scale the attribute of not becoming embrittled at very low temperatures, possessed by most copper alloys, has led to bronzes being widely used for cryogenic services such as liquid oxygen and nitrogen where temperatures below 180°C prevail.

Aluminum-bronze special alloy are most valued

Aluminum-bronze is a type of bronze in which aluminum is the main alloying metal added to copper, in contrast to standard bronze (copper and tin) or brass (copper and zinc). Aluminum bronze is the highest strength standard copper based alloy and is used where higher mechanical properties are required.

Frequently Asked Question

Do you have any question?

The ball valves operate with a ball inside the valve body. The ball is moved as to open and close the valve. Ball valves are some of the most common designs used in valve manufacturing.

The aluminium bronze gate valves use a gate to operate the valve. The gate opens or closes the valve and is connected to the valve stem. The valve stem is fitted with a handle which moves the stem in up or down and the gate opens and closes the valve.

Nickel Aluminium Bronze Hydrant Valves Why Use NAB Valves ? The advantages of NAB valvesare significant. They are particularly suitable and useful for seawater servicewhere corrosion performance, particularly where its resistance to chloride pitting is excellent.
