Fisher 4" ET CL150 Control Valve with 667 Size 45 Pneumatic Actuator

The Fisher ET series control valve is a robust, single-port globe-style valve designed for precise throttling and on-off control in demanding industrial applications such as oil and gas, chemical processing, power generation, and refining. This 4-inch model features a CL150 pressure rating, making it suitable for moderate pressure systems up to 275 PSIG at 100°F. It includes a Fisher 667 pneumatic diaphragm actuator (size 45) for reliable actuation with a bench set range of 10-40 PSI, ensuring smooth operation and fail-safe performance. Key benefits include easy maintenance with the easy-e design, which allows quick trim replacement without removing the valve from the line, high flow capacity (Cv up to 200 depending on trim), and excellent shutoff capabilities with metal-to-metal or soft seating options. Compared to similar valves like those from Masoneilan or Valtek, the Fisher ET offers superior cavitation resistance and noise reduction through optional anti-cavitation trim. Drawbacks may include higher initial cost and the need for compressed air supply for the actuator. This unit appears used with some internal wear but is in functional condition, ideal for process control where reliability and precision are critical.
