Moore 61L Pneumatic Booster Relay

Description:

The Moore 61L Booster Relay is a pneumatic signal relay designed to reproduce an input pressure signal in a 1:1 ratio while providing increased flow capacity for faster actuator and control valve response. It is commonly used in valve positioning systems, pneumatic control loops, and process automation applications where input isolation or higher output flow is required. The 61L combines moderate accuracy with moderate flow capacity, making it suitable for industrial control systems in manufacturing, power generation, oil and gas, and chemical processing industries.

Applications:

The Moore 61L Booster Relay is widely used with pneumatic control valves, diaphragm actuators, valve positioners, process control loops, instrumentation systems, and industrial automation equipment. It amplifies pneumatic flow without altering the control signal, allowing large actuators to stroke more quickly and improving overall control system responsiveness. The relay is suitable for indoor or outdoor installations and operates with clean, dry instrument air in applications requiring dependable 1:1 pneumatic signal transmission.
