SAF / SAD actuator

Fail-safe function, individual adaptations, complete systems

Armaturenfabrik pneumatic actuator type SAF SAD from AMG-Pesch, automation of valves such as ball valves and butterfly valves

Product information

Die pneumatischen einfachwirkend or doppeltwirkend Doppelkolben actuators SAF / SAD from AMG-Pesch are the perfect solution for automating industrial valves. They stand out through a robust design, high reliability and versatile adaptation options – ideal for the chemical industry, energy, water technology and mechanical engineering.

Features and advantages

Namur interface for easy mounting of solenoid valves and limit switches
Fail-safe function on the SAF through a spring pack
Robust construction: for ball valves, butterfly valves and other valves
ATEX compliant: suitable for potentially explosive areas
Individual adaptation: special flanges, limit switches, heating jacket possible
Complete systems: valve, actuator and accessories supplied ready to install
Certified quality: durable and low-maintenance

Areas of application

Automation of ball valves, plug valves and butterfly valves
Plants requiring a defined position on air failure
Corrosive environments and outdoor installation
Complete supply of valve, actuator and documentation

Advantages

SAF single-acting with spring return, SAD double-acting
Interfaces to ISO 5211 and VDI/VDE 3845
Special flanges, limit switches, heating jacket and ATEX possible
Valve, actuator and accessories from a single source

Selection and installation

The mode of action is the first decision: on air failure the SAF travels spring-actuated to a defined position, while the SAD delivers the higher torque for the same frame size. Neither can be changed afterwards.
