Electronic ball valve

Electric Ball Valves. Typically used for ON/OFF control of water, air, oil and other compatible media. Valworx electric ball valves use an electric actuator to open and close the valve. These valves are power-to-open and power-to-close. Valve positioner and fail close options are available.

What is a ball valve used for?

Ball valves use a metal ball with a hole bored through the center, sandwiched between two seats to control flow. Used in many hydrocarbon process applications, ball valves are capable of throttling gases and vapors and are especially useful for low flow situations.

How is a valve activated electronically?

Electric actuators can generate this force by transmitting it to the output shaft and then the valve stem. When pressure is applied to the valve stem, the valve's orifice opens or closes. Actuators have different levels of motor capacity (power) based on the torque they need to provide.

What is a disadvantage of a ball valve? Disadvantages of ball valves They are not suitable for slurry type applications due to cavities around the ball and seats. Slurries or other thick liquids tend to solidify or clog inside of the cavities, greatly increasing the operating torque of the valve and in some cases rendering the valve inoperable.18 Jun 2021 Ball Valves Advantages and Disadvantages https://johnvalves.com.au › discover-ball-valves-advantag...

Disadvantages of ball valves They are not suitable for slurry type applications due to cavities around the ball and seats. Slurries or other thick liquids tend to solidify or clog inside of the cavities, greatly increasing the operating torque of the valve and in some cases rendering the valve inoperable.

What is a pneumatic ball valve?

When someone says "pneumatic ball valve" they mean a regular ball valve with a pneumatic actuator. Valves built for automating typically have an industry standard (ISO 5211) 4-bolt mounting pad that the actuator mounts to.

What is the difference between solenoid and valve?

Electric valves are used to both regulate and switch systems such as fan coil ends. Solenoid is more suitable for specific requirements such as leaks and also while dealing with special fluids. Electric valves are used to simulate either liquid, gaseous or wind systems piping through AI controls.

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.

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.

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.

Are ball valves air tight?

The ball valve is often a valve of choice in pipeline applications, as it is very reliable and provides an air-tight seal when it is turned off, as well as being quick and easy to operate. They are quite compact and generally require little maintenance.

Are ball valves sanitary?

They're usually used in biopharmaceutical, chemical, medical, food, beverage, dairy, and other personal care applications like cosmetics. The ball valve is deemed sanitary because: The valve limits crevices and cavities which would otherwise trap media and encourage bacterial activity.

What is the advantage of a 3 piece ball valve?

Advantages of 3-Piece Ball Valves Changing seats and seals is more affordable than replacing the entire valve, and not having to remove the pipe connectors prevents a line shutdown should maintenance be required.

How does actuator ball valve work?

Pneumatic actuators control ball valves by the conversion of compressed air energy to mechanical motion. A rotary mechanical motion is required in a ball valve for a 90 degrees turn. Pneumatic actuator ball valves can be single-acting or double-acting.

How does an electro pneumatic actuator work?

The electro-pneumatic action is a control system by the mean of air pressure for pipe organs, whereby air pressure, controlled by an electric current and operated by the keys of an organ console, opens and closes valves within wind chests, allowing the pipes to speak.

How do actuated valves work?

The electric actuator generates this torque and transmits it to its output shaft, which is then connected to the valve's stem, or shaft. This, in turn, rotates the valve's ball or disc and opens or closes the orifice to allow flow through or block the flow.

What is electronic valve?

A vacuum tube, electron tube, valve (British usage), or tube (North America), is a device that controls electric current flow in a high vacuum between electrodes to which an electric potential difference has been applied.

Is a solenoid valve a ball valve?

A solenoid valve opens when an electric current flows through the coils and closes when it ceases to flow. A motorized ball valve moves with gears in either direction depending on its position – closed, open, or fully open (fully secure).

When would you use a solenoid valve?

Solenoid valves are used wherever fluid flow has to be controlled automatically. They are being used to an increasing degree in the most varied types of plants and equipment. The variety of different designs which are available enables a valve to be selected to specifically suit the application in question.

Where are ball valves located?

It is attached directly to the operating handle of the valve, which is usually located above or to the side of the device, often on the outside of a pipe assembly. By rotating the handle, typically one-quarter turn through 90 degrees, the ball is physically turned on its axis within the port.

How many types of valves are there in industry?

Industrial valves are of various types such as Gate Valves, Globe Valves, Ball Valves, Butterfly Valves, Check Valves, Pressure Valves, and Diaphragm Valves etc. These valves perform various functions working on a different working principle.
