Key Features:
- Bellows Seal Technology:
Both ARI-FABA®-Plus and ARI-FABA®-Supra valves come with a double wall bellows seal, ensuring a leak-tight seal even under challenging pressure conditions. This design is suitable for demanding applications requiring a high level of safety and reliability. - Material Options:
The body and bonnet are made from SA216WCB (for Class 150/300) and SA105 (for Class 300), with other components using materials like SA276Gr.420, SA240Gr.316Ti, and E347-16 for enhanced durability and resistance to high temperatures and pressures. - Plug Design:
The valves feature a plug with marginal seat as standard, with options for a balancing plug for applications involving high differential pressures. - Maintenance-Free Operation:
The ARI-FABA®-Plus series is designed for maintenance-free operation, with a lubricating nipple and locking device for ease of operation and long-term reliability. - Versatile Actuator Options:
The ARI-FABA®-Plus / -Supra ANSI series is compatible with pneumatic actuators (e.g., ARI-FA) for automated control, available in spring-closing and spring-opening configurations, ensuring seamless integration into automated systems.
Applications:
- Industrial Systems: Ideal for chemical plants, oil and gas applications, energy production systems, and HVAC where precise control over fluid and gas flow is required.
- Steam & Gas Regulation: These valves are commonly used in systems handling high-pressure steam and gases, ensuring a stable pressure and reliable shut-off function.
- Chemical Processing: The chemical version of the ARI-FABA®-Supra, with a flushed bellows seal, offers an optimal solution for systems handling corrosive or hazardous materials.
Design & Performance:
- Nominal Pressure: Available in Class 150 and Class 300, the valves are designed to handle pressures up to 51.1 bar (for ANSI 300) and temperatures up to 250°C, with the bellows seal protecting against leaks.
- Dimensions & Flow: The Kvs values for the valves range from 2.6 m³/h (for smaller DN sizes) to 1090 m³/h (for larger DN sizes), providing options suitable for both low and high-capacity flow systems.
- Valve Body Options:
- Straight-through with flanges (Class 150 and Class 300)
- Screwed sockets and socket weld ends (Class 300)
Additional Features:
- Limit Switch & Stem Extension:
The valves can be equipped with limit switches, stem extensions, and travel limiters to enhance control and adjustability in automated systems. - Balancing Plug for High Differential Pressures:
For systems with high differential pressures, a balancing plug is available, ensuring stable pressure regulation during operation. - Optional Pneumatic Actuator (ARI-FA):
The ARI-FA pneumatic actuator can be added to the ARI-FABA®-Plus / -Supra valves to automate their operation, with options for both spring-closing and spring-opening configurations.
Flange & Connection Dimensions:
- Flanges:
- Compliant with ASME / ANSI B16.5
- Socket Weld Ends / Screwed Sockets:
- Compliant with ASME / ANSI B16.11 and DIN ISO 228 (BSP)
