What is a Ball Valve?
A ball valve is a quarter-turn shut-off valve with a rotational motion that controls the flow of a liquid or gas through the use of a ball with a hole. The flow is restricted by turning the ball 90 degrees around its axis using a stem.
It can be controlled manually or automatically using an electric or pneumatic actuator.
Types of Ball Valves:
Floating ball valve
A floating ball valve features a ball, a valve, and a stem. The stem is connected to a slot at the top of the ball which allows the ball to rotate a quarter turn (90 degrees). The ball is free to float inside the valve body. The ball is held in the position by the compression of the two elastomeric seats against the ball.
Once pressure is applied, the flow will push the ball against the seat creating a bubble-tight seal. This type of valve design is capable of bi-directional shut-off. The floating valve is very difficult to operate when upstream pressure is high.
In a house, a float valve is installed in a water storage tank and flush tanks, so that water flow is stopped automatically once the tank is filled up with water.
Forged steel ball valve
A forged steel ball valve is a common type of valve used to control and regulate fluid flow. As the name suggests, it is a ball valve made out of forged steel.
A ball valve is opened and closed by rotating the lever handle clockwise and counterclockwise, respectively. When the ball hole is parallel to the fluid flow, the valve is said to be open, and when the ball hole is rotated at 90 degrees, the valve is said to be closed.
Trunnion ball valve
A short shaft like an extension called Trunnion is set in the body. The trunnion-mounted ball valve design features a trunnion anchoring at the top and bottom of the ball. The ball is supported by two floating or spring-loaded seats that remain in constant contact with the ball. Regardless of the pressure, this design guarantees a positive seal on both downstream and upstream seats.
Advantages of Ball Valves:
Compact in size
Flexibility in design
Long life expectancy
Low-pressure drop (flow is almost unrestricted)
Reduced chances of leakage
Requires little maintenance
Suitable for emergency power outages
Suitable for use in high-pressure environments
Do not require lubrication
Easy to use
Corrosive environments aren’t an issue
Disadvantages of Ball Valves:
Body cavity filled with fluid
Not suitable for high temperature
Not suitable for throttling
The partially exposed seat erodes quickly in a throttling position due to the impact of high-velocity flow.
These valves with drive mechanisms should be positioned upright and cannot be used for throttling because the valve handle has been rotated.
Industries that use Ball Valves:
Oil & Gas, Chemical, Petrochemical, Refinery
Food & Beverage Equipment
Vehicle Wash Systems
Water Treatment Equipment
Chemical Admixtures & Treatment
Vacuum and cryogenic services
