Semco RV-15 14x14 Stainless Steel Rotary Airlock Valve 1.5 CFR 304SS With Motor

Semco RV-15 Rotary Airlock | 304 Stainless Steel

Complete with Drive Motor & Gear Reducer | 1.5 CFR Capacity

Available for immediate acquisition is a heavy-duty Semco RV-15 rotary airlock valve. Constructed from high-grade 304 Stainless Steel, this unit is designed for the metered discharge of bulk solids in pneumatic conveying systems. Unlike cast iron units, this stainless steel build is ideal for food-grade processing, chemical handling, or applications involving corrosive materials. This is a complete assembly, including the motor and drive package, saving you the time and expense of sourcing a separate powertrain.

Key Features & Industrial Advantages

• Outboard Bearing Design: The bearings are mounted externally, separated from the main housing by a packing gland seal. This prevents product contamination and ensures that heat from your process does not reach the bearings, significantly extending the unit's lifespan.
• Complete Drive Package: Includes a high-torque gearmotor and chain drive assembly with a protective guard. The unit is pre-mounted on a structural steel base, making it ready for immediate integration into your production line.
• Corrosion-Resistant 304 SS: The stainless steel internals are highly resistant to pitting and chemical reactions, ensuring a long service life even in wash-down environments or when handling acidic/alkaline powders.
• Precision 8-Vane Rotor: Provides a high-efficiency air seal for both pressure and vacuum conveying systems. The 8-vane configuration ensures a minimum of two vanes are always in contact with the housing to prevent "blow-back."
• Easily Accessible Seals: Features adjustable packing glands for simple maintenance, allowing you to maintain a tight seal without disassembling the entire unit.
