A ball valve is a quarter-turn on/off valve with a rotational motion hollow ball-shaped disk that controls the flow of fluid.

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.

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
• Great shut on/off capability
• Long life expectancy
• Low-pressure drop (flow is almost unrestricted)
• Minimal leakage through wear & tear if properly used.
• Low maintenance cost
• Requires little maintenance
• Suitable for emergency power outages
• Suitable for use in high-pressure environments
• Time effective to operate
Disadvantages of Ball Valves:
• Body cavity filled with fluid
• Not suitable for high temperature
• Not suitable for throttling
• Not suitable for thicker media as sedimentation could occur and damage the valve disc & seat.
• Surge pressure could occur due to rapid closing and opening.
• 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:
• 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.

Pneumatic Actuated Ball Valve Manufacturer in USA
SVR Global is a reputed Pneumatic Actuated Ball Valve Manufacturer in USA. that provides a variety of pneumatically actuated valves. We test each of our pneumatically actuated ball valves to make sure it meets the needs of our customers. Additionally, we provide custom-built pneumatic actuators that are manufactured to meet particular industrial requirements.
Definition of a Pneumatic Actuated Ball Valve:
A pneumatic actuated ball valve is driven by a pneumatic actuator. This valve regulates the flow of fluid or gas through a ball with a bore.
In a pneumatic actuator, the operating power is generated by compressed gas or air. These actuators are quick to react but not really suitable for high-pressure environments due to the gas compressibility. They are available in two types, one is in spring return and the other is in double-acting configurations.
Features of Pneumatic Actuated Ball Valve:
• Pneumatic Actuated Ball Valve gives greater flow and wider media compatibility.
• Compact modular design of actuator provides direct mounting on the ball valve.
• Gives quick opening and closing and has a long life in the working cycle.
• Ball valve has both sides seal which is covered by internal ball and can give tight shut off after a year of cycle operation.
• This valve has a body that excludes aluminum hard anodized for corrosion protection and wears resistance.
Pneumatic Actuated Ball Valve is used in industries like:
• Textile Industry
• Water Industry
• Construction Industry
• Electric Power Industry
Advantages of Pneumatic Actuated Ball Valve:
• Pneumatic Actuated Ball Valve has the smallest fluid resistance compared to other valves.
• This valve seal has good sealing performance.
• Thrust bearing of the valve reduces the friction of the valve stem this results in the valve stem operating smoothly and flexibly for a long time.
• If the spring is set between the body and valve stem then the valve body exports generated static electricity.
Definition of a Pneumatic Actuator:
A pneumatic actuator is a device that transforms gas or compressed air into mechanical motion. It is sometimes referred to as air cylinders, pneumatic cylinders, and air actuators.
A pneumatic actuator operates by allowing a chamber to be filled with pressurized gas, most frequently compressed air. When it builds up enough pressure in contrast to the external atmospheric pressure, it causes the controlled kinetic movement of a device like a piston or gear. This motion could be circular or directed in a straight line.
It is used as an automated control to reduce the amount of time that humans are required to interact with a system's internal workings. This is particularly beneficial for automatic modulation and emergency shutdowns.

Definition of a Pneumatic Actuated Valve:

A pneumatically operated valve is used to control the medium flow with an actuator that operates on compressed air. This valve has the ability to sustain constant pressure. Pneumatic actuators reduce the number of operators required because everything is automated.
