Description

4 Way Spring Return MAC Valve – 911B-RA

The 4 Way Spring Return MAC Valve is a pneumatic directional control valve with 1/8″ ports designed for reliable airflow management in industrial automation and compressed air systems. Manufactured by MAC Valves, the 911B-RA valve provides directional air control for compatible pneumatic machinery, actuators, and industrial equipment.

Featuring a spring return configuration, this pneumatic valve is designed to return to its designated default position when the actuating signal is removed. This functionality makes spring return valves useful in pneumatic systems requiring a defined resting position and controlled directional switching.

The MAC 911B-RA valve features a labeled main pressure operating range of 25 to 150 PSI, making it suitable for appropriately specified industrial compressed air applications.

What Is a 4 Way Spring Return Valve?

A 4 way spring return valve is a directional control component used to manage compressed air flow within pneumatic equipment.

In a spring return configuration, an internal spring returns the valve mechanism to a designated default position after the actuating force or signal is removed. This allows equipment designers to establish a predictable valve position when actuation is no longer present.

Spring return valves are commonly incorporated into pneumatic control systems operating cylinders, actuators, and automated machinery.

Why Choose MAC Pneumatic Valves?

MAC Valves manufactures pneumatic control components used across industrial automation and manufacturing applications.

The MAC 911B-RA provides a recognizable model designation for customers sourcing compatible pneumatic replacement components. Matching the correct valve configuration, actuation method, operating pressure, and connection specifications is essential when replacing an existing valve.
