Pneumatic Actuator BI-TORQ BI45SSSR Stainless Steel, Spring Return

New, in original box. BI-45-SS-SR

Product Overview:

The BI-TORQ BI45SSSR Pneumatic Actuator is a high-quality, compact pneumatic actuator featuring a rack and pinion design that ensures consistent torque output. This model, part of the BI-Series, is housed in 304 stainless steel, making it ideal for use in harsh or corrosive environments where sanitary conditions are critical. Its robust construction and spring return (SR) mechanism make it suitable for industries such as pulp and paper, marine, and dairy, where corrosion resistance and reliable performance are essential.

The anti-blowout system safeguards the actuator from damage due to over-pressurization, while its durable precision-cast pistons ensure full engagement with the pinion. The actuator’s ISO 5211 bottom mounting pattern allows for direct mounting to compatible valves, and the NAMUR standard configuration supports easy mounting of solenoids, limit switches, and positioners for precise control and feedback.

Key Specifications:

• Model: BI45SSSR
• Housing Material: 304 Stainless Steel (Corrosion-resistant)
• Actuation Type: Pneumatic, Spring Return (SR)
• Design: Rack and pinion for consistent torque output
• Air Supply Pressure:
  • Standard: 80 psi
  • Maximum Pressure Rating: 120 PSI (8 BAR)
• Mounting Standards:
  • ISO 5211 for bottom mounting to valves
  • ISO and NAMUR for top mounting of limit switches and positioners
  • NAMUR air port configuration for easy solenoid valve integration
• Output Design: Star pinion for flexible valve mounting

Key Features:

• Corrosion-Resistant Stainless Steel: The 304 stainless steel housing is ideal for damp, corrosive environments, ensuring durability and longevity in industries such as marine, pulp and paper, dairy, and chemical processing.
• Spring Return Mechanism: Automatically returns the valve to its default position when air pressure is removed, enhancing safety and reliability in critical applications.
• Anti-Blowout System: Prevents damage from over-pressurization, protecting the actuator in high-pressure conditions.
• ISO 5211 and NAMUR Standards: Ensures compatibility with a wide range of valves and accessories, simplifying installation and integration into automated systems.

Applications:

• Pulp and Paper: Ideal for environments with high moisture and the need for corrosion-resistant equipment.
• Marine Industry: Suitable for use in corrosive marine environments where stainless steel is required for longevity.
• Dairy and Food Processing: The sanitary design and corrosion resistance make it ideal for food-grade applications.
• Chemical Processing: Handles harsh chemicals and corrosive substances with its 304 stainless steel construction.
• Water Treatment: Provides reliable valve actuation in damp or chemically reactive environments.

Pros:

• Highly Corrosion Resistant: 304 stainless steel construction ensures long-term durability in harsh environments.
• Flexible Mounting Options: ISO 5211 and NAMUR standards allow for easy integration with a variety of valves and automation accessories.
• Safe and Reliable: Spring return and anti-blowout features provide added safety and operational reliability.
• Customizable Actuation: Easily switch between double-acting and spring-return modes, or adjust torque based on air pressure.

Cons:

• Requires Compressed Air: Depends on a compressed air system for actuation, which may limit its use in locations without access to such systems.
• Manual Setup: While it’s designed for easy mounting, manual setup may still be required for complex applications.
