Fisher™ Lever-Lock Handlever Actuator
The Fisher™ Lever-Lock Handlever Actuator by Emerson provides secure, precise manual control for quarter-turn valves with a spring-loaded locking mechanism for safety.
The Fisher™ Lever-Lock Handlever Actuator, engineered by Emerson, is a manual valve actuator designed to provide positive, precise, and secure control for quarter-turn rotary valves such as ball, plug, and butterfly valves. This actuator uses a mechanical lever and lock mechanism that enables operators to manually open or close valves quickly and reliably, making it ideal for applications where manual control and safety interlocking are essential.
The Lever-Lock design incorporates a spring-loaded locking mechanism that securely holds the valve in the selected position, preventing accidental movement caused by vibration, system pressure, or unauthorized operation. Its compact, rugged construction ensures durability and dependable operation even in harsh industrial environments such as oil and gas facilities, refineries, chemical plants, and power generation systems.
With simple installation, low maintenance requirements, and high reliability, the Fisher Lever-Lock Handlever Actuator is the preferred choice for manual isolation and emergency shutdown (ESD) applications requiring mechanical security and precision valve positioning.
