Gun Metal / Brass Ball Valve PN16 Nickle Plated Heavy Quality

A ball valve is a shut off valve that controls the flow of a liquid or gas by means of a rotary ball having a bore. By rotating the ball a quarter turn (90 degrees) around its axis, the medium can flow through or is blocked. They are characterized by a long service life and provide a reliable sealing over the life span, even when the valve is not in use for a long time. As a result, they are more popular as a shut off valve then for example the gate valve.
Bronze Valves
Bronze is traditionally made of a mixture of copper and tin. It is more resistant to cracking than something like iron, is malleable, and can be cast or machined into valves and other components.

Pros of Brass Ball Valve

There are a few advantages associated with brass ball valve. These are:• Low cost

• High ductility levels
• Corrosion-resistance

Housing assembly

The assembly of the valve housing can be divided in three commonly used designs: one-piece, two-piece and three-piece housings. The difference is how the valve is assembled and this affects the possibilities for maintenance or repair. The operation of thevalves is the same in each embodiment.
• One-piece: This is the cheapest variant. The two parts which enclose the ball are pressed or welded. The valves can not be opened for cleaning or maintenance. This type is generally used for low-demanding applications.
• Two-piece: Two-piece valves can be disassembled for cleaning, servicing and inspection. Often, the parts are connected via a threaded connection. The valve must be completely removed from the pipe in order to separate the two parts.
• Three-piece: More expensive valves have often three pieces. The parts are generally clamped together by bolt connections. The advantage of this embodiment is that the valve can be serviced without removing the entire valve from the pipeline.
