Ball valves enjoy massive popularity thanks to their compact and low maintenance design that requires no lubrication while still offering users a tight seal with minimal torque. Ball valves are also the least expensive option when it comes to choosing among all of the valve arrangement types.
The biggest disadvantage of ball valves is that most designs have poor throttling characteristics that can cause the seat of a ball valve to easily erode. This has been remedied somewhat with the trunnion mounted ball valve design, but should still be a consideration for those looking at ball valves for situations where high throttling is a must.
Ball valves are also commonly chosen thanks to their ability to be successful used across a range of applications and markets. As mentioned before, ball valves are a big hit with the oil and natural gas industry, but also find a place in many manufacturing sectors, chemical storage, and even residential uses.
