Angle Seat Valves

Festo Angle Seat Valves

Festo angle seat valves are engineered for high-flow, high-durability control of liquid and gaseous media in industrial process systems. Their angled seat design delivers significantly higher flow rates compared to conventional globe valves, while maintaining tight shutoff, fast response, and long service life—even in challenging environments.

These valves come in pneumatically actuated configurations with normally-open, normally-closed, or double-acting functionality, allowing flexible adaptation to flow control, shutoff, and dosing applications.

⭐ Important: Angle seat valves provide extremely high flow capacity, long service life, and excellent performance under high temperatures and pressures—making them a top choice for demanding process automation tasks.

Design & Functionality

Festo angle seat valves operate using a piston-actuated mechanism that lifts a seal off the valve seat at an angle—maximizing the flow path and reducing pressure loss. The robust stainless-steel valve body and advanced sealing technology ensure reliable operation with hot, corrosive, or contaminated media.

Available configurations include:
• Normally-closed (NC) for fail-safe shutoff
• Normally-open (NO) for continuous flow applications
• Double-acting versions for controlled opening and closing
• High-temperature variants for steam
• Chemical-resistant models for aggressive media

These valves are optimized for high durability, excellent tightness, and long maintenance intervals, ensuring stable operation across industrial applications.

⭐ Important: The angled seat design significantly increases flow rates compared to traditional valve types, improving process efficiency and reducing system energy loss.

Total Crossed Beams

(Applied to the functional coverage of valve families)

Comprehensive coverage of process control needs across multiple valve body sizes, seal materials, and actuation types.

Ensures complete operational functionality, whether the requirement is fast switching, high pressure tolerance, or high-temperature operation.

Engineered to maintain consistent flow, sealing integrity, and switching performance across a wide operating range.

Beam Pitch Options

(Translated as: valve sizes, seals, flow capacities, media compatibility)

Broad range of body sizes, Kv/Cv flow ratings, and seal materials to meet different process demands.

Selectable configuration options include:
• Stainless steel body for harsh environments
• PTFE, EPDM, or FKM sealing options
• Port sizes typically from ¼" to 2" (varies by model)
• High-temperature-capable versions for steam and thermal systems
• Manual override options
• Visual position indicators

This ensures each valve can be optimized for flow performance, chemical resistance, steam compatibility, sanitary environments, or general-purpose industrial control.

⭐ Important: The wide range of flow capacities and sealing materials ensures suitability for nearly any liquid, gas, or steam application.

Intrinsic Synchronism

Internal piston and seal mechanics ensure smooth, synchronized opening and closing with minimal wear.
Optional feedback modules and position detection accessories provide enhanced monitoring for automated systems.

Ensures precise actuation and stable flow control, supporting long-term repeatability in process environments.
