Ball valves
with pneumatic drive
Ball valves with pneumatic actuator in stock
On the pages of our catalog you will find a wide range of automated units for various industries.
We complete stainless steel (AISI 304/316) taps for the food, pharmaceutical and chemical industries, where sterility and corrosion resistance are important. We also have brass and steel models for general engineering, water treatment and energy applications.
The range includes:
- Coupling (threaded) devices for small and medium diameter pipelines.
- Flange models designed for high-pressure industrial lines.
- Valves with two-way or three-way flow distribution of the working medium.
Each ball valve with a pneumatic actuator undergoes input torque compatibility control, which guarantees correct and long-lasting operation of the valve-actuator pair.
How to choose a pneumatic actuator for your crane
Actuator selection is a purely engineering task that does not tolerate approximations. The choice depends on the diameter of the pipeline, operating pressure and operating conditions.
For small systems, a standard rotary actuator is sufficient. While large industrial pipelines require reinforced actuators with positioners and limit switches.
It is important to consider the speed of opening and closing, as well as the possibility of integration with automation systems. UKSPAR offers solutions for simple flow shut-off and for complex technological processes with precise regulation.
The principle of operation of a pneumatic actuator
The pneumatic actuator operates by means of compressed air supplied to the actuator chambers. The air flow creates a movement that is transmitted to the stem and ball inside the valve. This ensures a quick and reliable shut-off of the flow of liquid or gas.
For greater functionality, additional elements are used:
- solenoid valve for controlling air supply;
- positioner for precise adjustment of the ball position;
- limit switches to monitor the status of the crane.
Such a system allows you to integrate equipment into complex automated lines.
Equipment
Pneumatically operated cranes can be supplied in various configurations:
- basic version with rotary drive;
- models with positioner for precise adjustment;
- complete with solenoid valve for remote control;
- versions with limit switches for status signaling.
Thanks to this, the user can choose the optimal solution for specific operating conditions.
Advantages of automated control
The use of pneumatic shut-off valves has significant advantages over manual control or the use of electric actuators in production.
- Maximum speed of action. Instant response to control system commands.
- Explosion-proof. The absence of electrical components completely eliminates the risk of sparks, which is important for the petrochemical industry.
- Reliability and durability. The design is designed for millions of operating cycles without losing its original characteristics.
- Power failure safety. Spring return models will automatically close the pipeline in the event of a compressor shutdown.
Remote control allows you to integrate the valves into the overall dispatching system of the enterprise, minimizing the presence of personnel in hazardous areas.
Areas of application
The price of a pneumatically actuated ball valve is justified by its functionality and safety. It is a standard for the food industry (dairies, breweries, juice production). Such valves are widely used in water treatment plants for reagent dosing, in the pulp and paper industry and in oil refineries.
Wherever high operation frequency, speed of response and reliability are required, pneumatic systems from UKSPAR demonstrate the best results.
