What is a Ball Valve?
A ball valve is a quarter-turn on/off valve with a rotational motion that controls the flow of a liquid or gas.
Ball valves are referred to as quarter-turn valves because the ball rotates 90 degrees between the fully open and fully closed positions. On/off valves either allow flow (on) or obstruct it completely (off). These valves are also known as isolation valves, because they can effectively shut down flow into a segment of a system, often for maintenance to be performed.
A ball valve comprises a valve housing, which is often a metal casting and a perforated ball. The flow is restricted by turning the ball 90 degrees around its axis using a stem.
Being a valuable ball valve manufacturer in USA, SVR Global offers a wide range of Ball Valves. Our Ball Valves are tested to ensure they meet all of our clients’ requirements. We also offer customized Ball valves that are tailored to specific industrial demands.
Advantages of Ball Valves:
- Compact in size
- Corrosive environments aren’t an issue
- Do not require lubrication
- Easy to use
- Fast-acting
- Flexibility in design
- Inexpensive
- 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
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.
- Should be positioned upright and cannot be used for throttling because the valve handle has been rotated.
Industries that use Ball Valves:
- Automotive
- Chemical
- Cryogenic
- Oil & Gas
- Petrochemical
- Power Processing
- Vacuum
- Water Treatment
Types of Ball Valves:
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.
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.
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.
