Neles Jamesbury 1/2" 5150 CL-150 Ball Valve with Quadra-Powr II Actuator

The Neles Jamesbury 1/2" 5150 CL-150 Ball Valve with Quadra-Powr II Actuator is a robust, pneumatically actuated ball valve assembly designed for precise flow control in industrial applications. This unit features a 316 stainless steel ball valve body rated for Class 150 pressure, making it suitable for corrosive environments such as chemical processing, oil and gas, and water treatment. The Quadra-Powr II spring-diaphragm actuator provides reliable fail-safe operation, with spring-return functionality for emergency shutoff. Key benefits include high torque output for tight shutoff, low maintenance due to its sealed design, and compatibility with automated control systems. Compared to similar products like those from Fisher or Valtek, it offers superior corrosion resistance and a compact footprint, though it may require periodic diaphragm inspections in harsh conditions. The assembly includes accessories like an ASCO solenoid valve for pneumatic control, an Accord Controls limit switch for position feedback, and a Flowserve UltraSwitch for additional monitoring. Ideal for on/off or throttling services, it ensures safety and efficiency in demanding pipelines. Drawbacks include higher initial cost and the need for compressed air supply. Overall, this used unit shows moderate wear but remains functional for secondary market applications.
