Product Description
The Festo VAVA series stroke reduction devices are mechanical stop elements designed for precise opening stroke limitation on pneumatic actuators . These components mount directly onto compatible valves or actuators to physically limit the stroke length, providing adjustable end-stop functionality for applications requiring controlled valve opening . Available with or without integrated cushioning (damping), these stop elements are rated for use in potentially explosive atmospheres (ATEX Zones 1,2,21,22) and offer high ingress protection (IP6X) for demanding industrial environments .
Key Features & Advantages:
-
Precise Opening Stroke Limitation: Provides mechanical limitation of the actuator opening stroke, enabling precise control of valve opening positions for applications requiring adjustable flow rates or partial valve opening
-
With or Without Integrated Cushioning: Available in two design configurations: VAVA-F12-H-H1 features opening stroke limitation without cushioning, while VAVA-F12-H-H6 features opening stroke limitation with integrated cushioning for shock absorption at the end of stroke
-
High Corrosion Resistance Options: Available with Corrosion Resistance Class CRC 2 (moderate corrosion stress for VAVA-F12-H-H6) or CRC 3 (high corrosion stress for VAVA-F12-H-H1), allowing selection based on environmental exposure severity
-
IP6X Degree of Protection: Provides dust-tight protection against ingress of dust, ensuring reliable operation in dusty industrial environments
-
ATEX Explosion Protection Zones 1,2,21,22: Certified for use in potentially explosive gas and dust atmospheres (Zones 1, 2, 21, 22), making these stop elements suitable for hazardous industrial applications in chemical, petrochemical, and pharmaceutical facilities
-
Wide Temperature Range: Operates reliably from -10°C to 80°C (VAVA-F12-H-H6) or -50°C to 100°C (VAVA-F12-H-H1), ensuring consistent performance across extreme industrial environmental conditions
-
LABS (PWIS) Conformity (H6 variant): VAVA-F12-H-H6 complies with VDMA24364-B2-L standards for paint-wetting impairment substances conformity, making this stop element suitable for paint shop environments and applications sensitive to paint defects
-
Durable High-Alloy Stainless Steel Construction: Manufactured with high-alloy stainless steel nuts, screws, connectors, and shock absorber, providing exceptional mechanical strength and corrosion resistance for long-lasting industrial performance
-
EPDM Seals: Features EPDM (ethylene propylene diene monomer) sealing material, offering excellent resistance to compressed air, water, and various media for reliable sealing performance
-
Flexible Mounting Position: Allows any mounting position, providing installation flexibility for complex pneumatic system configurations without orientation restrictions
-
Lightweight to Moderate Weight Range: Weighs approximately 250 g to 278 g depending on variant (VAVA-F12-H-H1: 253 g, VAVA-F12-H-H6: 249 g to 278 g), facilitating easy installation
-
RoHS Compliant: Manufactured without restricted hazardous substances, meeting stringent environmental compliance standards
