The Fisher™ EH Series Control Valves are engineered for high-pressure and severe service applications where reliable performance is critical. Featuring a robust cage-guided design with metal seals, these valves are built to handle demanding conditions across various industries .
The series includes different models such as EHD, EHS, and EHT, offering flexibility for specific flow characteristics and application needs . These valves are designed with pressure-balanced plugs (EHD and EHT models) to optimize performance under high pressure drops . With options for standard Cavitrol™ III or Whisper Trim™ III cages, the EH series provides effective noise and cavitation control, making it a versatile solution for challenging fluid control processes .
Key Features:
Rugged Construction: Designed with metal seals and a cage-guided design for durability in high-pressure environments .
High-Pressure Capability: Conforms to ASME B16.34 standards with pressure class ratings up to CL2500, suitable for extreme pressure and temperature conditions .
Superior Sealing Options: Equipped with ENVIRO-SEAL™ or HIGH-SEAL packing systems to help prevent process fluid leakage and meet environmental standards .
Effective Noise & Cavitation Control: Optional Cavitrol™ III or Whisper Trim™ III cages are available for noise attenuation and cavitation management .
Flow Direction Versatility: Configurable for flow-over or flow-under operation depending on the specific model and trim (e.g., with Whisper Trim III cage or diverting plug) .
High Shut-Off Capability: Can achieve up to Class V shut-off (per ANSI/FCI 70-2) at high temperatures, ensuring tight sealing .
