Powered Ball Valve


For example, an “electrically powered ball valve” is a ball valve with an electric drive mounted on it. While manufacturers mainly offer stainless steel solenoids and brass options, the construction of ball valves is much more diverse. Due to the variety of building materials, the range of ball valves can meet more diverse chemical compatibility requirements. Ball valves also offer more diversity in final connectivity than most solenoids.

As a result, a manufacturer can plot multiple flow patterns, allowing greater design flexibility … 3- and 4-way multi-track ball valves with multiple flow patterns, used for deflection or mixing applications. The metal sealed ball valve can be used in the piping system or medium temperature in the metallurgical system, the electrical energy system, the petrochemical equipment and the district heating system.

They have a direct connection to the valve stem and can rotate it a quarter turn. Actuators or handles are mounted on the valve handle and act as controls to open or close the valve. With the right power source for your project, you can reduce maintenance costs, increase uptime and maximize safety. These mechanical devices can be driven in a variety of ways, including electrical, pneumatic and hydraulic. Each option offers different advantages and disadvantages making it suitable for different applications.

Features of 3-piece ball valves Our Multi-Choice and Tri-Pro valves are dynamic, high-quality 3-piece valves that are durable and expensive… Pneumatic drives are capable of producing some of the highest closing forces of all types of drives. Some pneumatic drives can have a maximum pressure capacity of 250 psi and can generate forces up to 40,000 lb. This type of drive also allows relatively fast closing speeds of up to 2 m / s. Both the speed and strength of the drive can be easily adjusted by adjusting a system of pressure relief valves or flow controllers.

A pneumatically operated ball valve is powered by air pressure, while a hydraulically driven ball valve is powered by hydraulic fluid pressure. The air-activated ball valve has a compact structure, reliable sealing, simple structure and convenient maintenance. The sealing surface and spherical surface are often in a closed state, which is not easy to erode in the middle. It is suitable for general working media such as water, solvent, acid and natural gas. It is also suitable for media with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene, and is widely used in various industries.

The COVNA high-pressure pneumatically driven ball valve has the characteristics of compact structure, small size, reliable operation, good sealing performance and easy maintenance. Ball valves with drives are inserted into systems to control opening and closing of valves. To measure the current, they are often equipped with measuring monitors or flow meters.

These 1/4 return control ball valves are more compact, lightweight and much cheaper than comparable balloon valves and segmented control valves offered by other companies. Flow-Tek control valves provide fast response times for control signals thanks to advanced digital performance control and the inherent strengths of ball valves. These valves exceed class VI by offering airtight closure to zero punctures. Other features include superior range and repeatability, high flow capacity, ability to run on solid and fibrous liquids, ease of maintenance and exceptional interface with PLC and computer command signals.

To open or close the valve, pneumatic drives take up to 1 full second for 12 seconds depending on the model. Gemini electric drives take about 6 seconds, while other manufacturers can last more than 25 seconds or more. A three-part ball valve is a valve that opens at both ends to provide easy access to the valve’s internal components for maintenance and repair purposes.

The hole is known as a gate or hole and when opened it is aligned with the valve body to allow current. The ball is in a body and uses a stem connected to the output shaft, in this case a pneumatic or electric drive. From the closed position, turn 90 ° counterclockwise to open and 90 ° clockwise to close. Different industries use segmented or port-in-v ball valves van bi điều khiển bằng khí nén to control flow in modulation applications. A manufacturer can mechanically operate segmented or V-gate ball valves or by using pneumatic or electrical energy to operate them based on a signal received from a pilot. In addition, manufacturers use smaller V-segmented or gate ball valves in upstream applications and larger sizes in medium flow applications.
