Waukesha Cherry-Burrell W61T-LS 4.0" Sanitary Valve with Actuator

The Waukesha Cherry-Burrell W61T-LS 4.0" Sanitary Valve is a high-performance, air-operated shut-off valve designed for hygienic applications in the food, beverage, dairy, and pharmaceutical industries. This model features a long-stroke (LS) throttle design, enabling precise flow control and reliable shut-off in sanitary processing lines. Constructed from durable 316L stainless steel, it ensures corrosion resistance and easy cleanability, meeting 3-A sanitary standards for CIP (Clean-In-Place) and SIP (Sterilize-In-Place) processes. The air-to-raise actuator provides efficient pneumatic operation, with a Viton elastomer stem seal for enhanced durability and leak prevention in demanding environments. Key benefits include minimal product shear, low pressure drop, and modular design for easy maintenance, offering advantages over competitors like Alfa Laval or GEA valves in terms of longevity and customization. Drawbacks may include higher initial cost and the need for compressed air supply. This valve excels in applications requiring aseptic flow diversion, such as mixing tanks or transfer lines, and its robust build reduces downtime compared to standard globe valves. Based on visual analysis, this unit appears used with minor surface wear but no major damage, making it suitable for refurbishment or direct reuse.
