Fisher ET, EAT, and ETR Control Valves
Product Description
The Fisher™ ET, EAT, and ETR control valve series are versatile, high-performance, sliding-stem globe valves engineered for reliable throttling control across a wide range of industrial process applications. These valves are designed to deliver accurate, stable control performance while maintaining long-term durability under demanding operating conditions.
The ET Series is the standard globe-style configuration, the EAT Series offers a high-capacity angle valve design for specialized flow conditions, and the ETR Series provides a reduced-capacity version optimized for precise control at lower flow rates.
Constructed with robust materials and featuring proven trim technologies, these valves provide excellent shutoff capability, resistance to corrosion and erosion, and compatibility with a broad range of fluids—including liquids, gases, and steam. With Fisher’s modular actuator and packing options, the ET/EAT/ETR series ensures superior performance in industries such as oil & gas, chemical, petrochemical, power generation, and general industrial process systems.
