Eccentric Half Ball Valve， when opened, the ball is hidden in the valve cavity, and the flow area is large. When the valve core is closed, the spherical surface of the valve core is progressive along the valve seat, with a shearing function, which can effectively remove scaling obstacles and achieve reliable sealing. It is suitable for occasions where strict requirements are required such as sewage treatment, pulp, alumina, urban heating, oil, natural gas, liquid and solid two-phase mixtures, or media that are prone to chemical crystallization.
There are two different types of ball valves: top-entry ball valves and side-entry ball valves. These two types vary in the way they are installed and disassembled. Today, we will discuss the differences between the two types.
Top-Entry Half Ball Valves
Top-entry ball valves, also known as bolted bonnet ball valves, are designed in such a way that their internal components can be installed and removed from the top of the valve. This installation process makes it easier to carry out maintenance and repairs without having to remove the entire valve from the pipeline. The valve's ball, stem, seat, and other internal components are all accessed from the top of the valve.
One of the major advantages of top-entry ball valves is that they can be installed or repaired without shutting down the pipeline or the whole system. The valve can be closed and disassembled from the top while the downstream pipes are still functioning. This saves a lot of time and cuts down on production losses.
Side-Entry Half Ball Valves
Side-entry ball valves, also known as eccentric half-ball valves, have a different structure from top-entry ball valves. The internal components of side-entry ball valves are accessed from the side of the valve.
Side-entry ball valves are usually smaller in size compared to top-entry ball valves and are used in applications where space is at a premium. They are also commonly used in applications where the pipeline is already pre-installed and cannot be removed to install a new valve. Side-entry ball valves have a one-piece body design, which makes them easier to install.
When it comes to maintenance and repairs, side-entry ball valves require the entire valve to be removed from the pipeline, which can be time-consuming and labour-intensive. However, some manufacturers have designed side-entry ball valves to be easier to maintain and repair.
In conclusion, both top-entry and side-entry ball valves have their advantages and disadvantages. Companies should choose the type of ball valve to be used based on their specific application requirements, maintenance schedules, and budget considerations.
