Pneumatic Actuated Ball Valve Manufacturer in Europe

Valvesonly Europe is a leading Pneumatic Actuated Ball Valve Manufacturer in Europe, with manufacturing facilities in Germany and Italy. Our valves combine precision-engineered ball valve designs with advanced pneumatic actuators to deliver fast, reliable, and safe flow control. Designed for on/off and throttling applications, our range includes 2-piece, 3-piece, 3-way, floating, trunnion-mounted, and metal-seated ball valves for diverse industrial applications.

Function & Working

Pneumatic actuated ball valves are quarter-turn valves operated by compressed air. The actuator uses single-acting (spring return) or double-acting mechanisms to rotate the ball 90°, ensuring quick opening or closing of flow.

• Floating ball design for low-pressure, compact applications.

• Trunnion-mounted design for high-pressure, large-diameter pipelines with reduced torque.

• 3-way ball valves for diverting or mixing flows.

• Metal-seated ball valves for high-temperature or abrasive service.
  Automation can be enhanced with solenoid valves, limit switches, positioners, and air filter regulators, making them ideal for integration into PLC or SCADA systems.

Advantages

• Quick quarter-turn operation with compressed air

• Available in floating, trunnion, 2-way, and 3-way configurations
