Shafer RV-Series Hydraulic Valve Actuator
The Shafer RV-Series Hydraulic Valve Actuator by Emerson delivers high torque, precision, and reliability for quarter-turn valves in demanding offshore, pipeline, and refinery applications.
The Shafer RV-Series Hydraulic Valve Actuator is a high-torque, heavy-duty rotary actuator engineered to provide precise and dependable control of quarter-turn valves, such as ball, plug, and butterfly valves, in critical service applications. Developed by Emerson, the Shafer RV-Series is built to perform in the toughest industrial environments—offshore, subsea, pipeline, and refinery operations—where reliability, safety, and performance are paramount. This actuator utilizes a hydraulic scotch yoke mechanism, designed to produce high torque output at both ends of the stroke, ensuring smooth, efficient valve operation even under high-pressure or high-cycle conditions. The hydraulic power design provides superior control accuracy, speed regulation, and fail-safe capability, making it suitable for both on/off and modulating control applications. The Shafer RV-Series is available in double-acting and spring-return (fail-safe) models, allowing for customized solutions based on system safety and operational needs. It features rugged carbon steel construction, corrosion-resistant coatings, and sealed housings to ensure durability in harsh outdoor and marine environments. Engineered with precision hydraulic control systems, the RV-Series can be equipped with advanced accessories such as manual overrides, limit switches, position indicators, and hydraulic control manifolds for integration into complex automation networks. The result is an actuator that combines power, safety, and intelligence, ensuring years of reliable service in demanding process control applications.
