Automatic ball valve

Ball Valves are reliable and simple to use as on/off flow switching valves. Just a quarter turn opens or closes the valve. Automated with electric or pneumatic actuators. These valve packages are sized and pre-assembled for ease of selection.

What are motorized ball valves?

The SM series motorized ball valves are ideal for HVAC and industrial on/off and modulating applications. The quarter turn ball valve features a unique direct mount system that allows for extremely quick and easy actuator mounting, allowing for easy removal or replacement of the on/off compact electric actuator.

Which type of valve is automatic?

Control valves can also work with hydraulic actuators (also known as hydraulic pilots). These types of valves are also known as Automatic Control Valves. The hydraulic actuators will respond to changes of pressure or flow and will open/close the valve.

What are the types of ball valves?

Types. There are five general body styles of ball valves: single body, three-piece body, split body, top entry, and welded. The difference is based on how the pieces of the valve—especially the casing that contains the ball itself—are manufactured and assembled. The valve operation is the same in each case.

Why do ball valves fail?

Common Ball Valve Failures One of the most common types of ball valve failures involves a buildup of dirt and sediment within the valve, making it difficult to open and close. The use of solvent cement glue can also clog up the ball, causing it to stick to the inside of the valve and resist turning.

Is a ball valve good for control?

A ball valve is typically a quarter-turn valve with a perforated ball in the middle to control flow. These valves are known for being durable with excellent shutoff, but don't always offer very precise control.

How does an automatic ball valve work?

Ball valves use motors to rotate a ball with a hole in the center to control flow. When the hole is in line with the flow, the valve is fully open, and when it is turned perpendicular to the flow, it is closed. Most electric ball valves don't require power to hold position like solenoid valves.

How does actuated ball valve work?

Actuated ball valves are rotating ball type pipe valves that come without manual turn handles to allow installation with an actuator. The valves are used together with an actuator device to automate valve opening and closing and therefore control plumbing fluid rates.

What is the difference between motorized valve and solenoid valve?

Motorized ball valves are cylindrical valves that regulate fluid or gas flow through a pipe by opening and closing a disk-shaped valve attached to the center of a cylinder. The solenoid valve, on the other hand, uses electromagnetic coils to move fluid between two piping systems.

What is automatic valve?

Automatic control valves are specialty valves fitted with actuators that can be controlled by temperature or flow sensors. The valves are controlled by electrical, hydraulic, or pneumatic signals from sensors. The valves can be set to open, closed, or anywhere in between to accurately control flow.

What are the 3 types of automatic gas valves?

All of the most common types of automated valves fall into one of three main categories. They are linear, rotary, and self-actuated. There are a variety of valve types within each of these categories each having its own benefits.

What are the four types of valves?

The four valves in order of circulation are:

Tricuspid Valve. Has three leaflets or cusps.
Pulmonary Valve (or Pulmonic Valve) (link opens in new window) ...
Mitral Valve. Has two leaflets. ...
Aortic Valve. Has three leaflets, unless it's abnormal from birth, i.e., bicuspid aortic valve.

Why is it called a ball valve?

The term ball valve refers to the fact that the internal mechanism that is used to change the flow through the device is a spherical ball that has a hole drilled through it which serves as the valve's flow control.

What are the advantages of ball valves?

Advantages of Ball Valves

High efficiency. Due to the size of the opening in the ball, ball valves are considered high recovery valves since they have a low-pressure drop and high flow capacity.
Convenient usage. ...
Low maintenance. ...
Cost-efficient. ...
Robust. ...
Prone to blockages. ...
Struggle with long term throttling.

Where is ball valve used?

Ball valve is the most used fluid shutoff valve in upstream oil and gas production facilities, both onshore and offshore. They are also used in fuel gas systems feeding furnaces. Plug valves present the following advantages: Resistance to high pressure.

How long should a ball valve last?

A ball valve life expectancy is about eight to ten years. For such a simple mechanical device, the ball valve has enormous value to the gas and water industries.

Can a ball valve be repaired?

The only repair for a ball valve is replacing the packing washer. If the actual ball on the valve becomes deteriorated, it will leak. In that case, the entire valve must be replaced.

Which is better gate valve or ball valve?

Ball valves are more effective at forming a tight seal and have more reliability and longevity than gate valves, but tend to be more expensive. They are often used for shutoff and control applications. Because ball valves can open and close immediately, they are more likely than gate valves to cause water hammer.

What type of valve is best for flow control?

For flow control applications where a ball valve is possible, such as filling a tank to a reasonable degree of accuracy, a trunnion or v-port ball valve design is usually the best choice.

Can you throttle with a ball valve?

Ball Valves are also designed to be operated fully open or fully closed with any liquid containing particles that could scratch the ball. Many people use them successfully for throttling clear water. Ball valves have low pressure drops, open and close quickly, are simple, and are trouble free.
