Ball Valves & On-Off Valves

Festo Ball Valves & On-Off Valves

Festo’s ball valves and on-off valves provide a robust solution for the manual shut-off of compressed air in automation systems, enabling safe isolation, maintenance and modular network flexibility. These valves are built to proven standards and deliver consistent performance across many industrial use cases.

They are available in multiple variants (2/2-way, 3/2-way, manual actuation) and support both push-in connectors and threaded ports, enabling easy integration into existing pneumatic circuits.
⭐ Important: These valves offer complete bi-directional shut-off with minimal leakage and high durability — making them fundamental components in compressed-air safety and control systems.

Design & Functionality

The ball valve design uses a rotary ball with a bore that opens or closes the flow path when the manual lever is actuated. The soft-sealing design ensures reliable block of flow in either direction, and the mounting can be in-line or via threaded/bulkhead options.
Festo offers variants including:
• Ball valves with push-in tubing connections for compact pneumatics
• Threaded ball valves for larger pipe-based systems
• High-flow versions for demanding applications
• Corrosion-resistant versions for harsh environments

⭐ Important: The availability of both compact tubing and large-pipe threaded designs ensures that the valve can be used in everything from small actuator control to full compressed-air network shut-offs.

Total Crossed Beams

The Festo valve portfolio covers full shut-off capability across sizes, connection types and mounting configurations. This ensures that regardless of system size or complexity, a reliable isolation valve is available.

The design supports consistent sealing performance and flow interruption under varying system pressures and mounting conditions.

Beam Pitch Options

Variants cover a wide range of bore sizes, connection types and actuation modes:
• 2/2-way ball valves for simple shut-off
• 3/2-way ball valves for branch or diverter shut-off functions
• Push-in tubing connectors (OD 4–12 mm) and threaded ports (G¼–G1½)
• Materials ranging from brass to stainless steel, for standard to harsh-environment use
• Temperature and pressure ratings supporting general pneumatic system needs

⭐ Important: The wide array of connection options and materials allows precise matching of valve size, flow requirement and installation environment — so the valve performs optimally.

Intrinsic Synchronism

The internal ball and seat interface ensures rapid actuation, minimal leakage and repeatable shut-off performance. In modular systems, the valve mounts securely in-line or in housing blocks, ensuring tight alignment and reliable function.

These valves maintain positional consistency and provide secure shut-off even with changes in orientation, pressure or medium.

Operational Advantages

• Manual actuation offers immediate control and isolation for maintenance or emergency shut-off
• High-quality sealing ensures minimal leakage when closed and full flow when open
• Compact variants support installations where space is limited; threaded variants suit pipe-based networks
• Long service life due to durable materials and well-engineered sealing systems
Applications: Compressed-air supply shut-off, machine tool isolation, handling system maintenance, pneumatic system safety, automated manufacturing lines.
