Description

4 Way Spring Return MAC Valve – 911B-RA

The 4 Way Spring Return MAC Valve is a pneumatic directional control valve 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.

Key Features & Benefits

• 4-Way Directional Control: Directs compressed air between valve ports to operate compatible pneumatic cylinders and actuators.
• Spring Return Operation: Returns the valve to its designated resting position when the actuation signal is removed.
• MAC 911B-RA Model: Identifiable MAC Valves component for equipment maintenance and replacement.
• 25–150 PSI Main Pressure Range: Pressure range indicated on the product identification label.
• Industrial Valve Construction: Designed for integration into pneumatic machinery and industrial control systems.
• Pneumatic System Integration: Suitable for compatible air-operated equipment requiring directional control.
• Replacement Applications: Useful for maintaining pneumatic equipment originally designed for this valve configuration.

4 Way Spring Return MAC Valve – 1/4″ Ports

The 4 Way Spring Return MAC Valve with 1/4″ Ports is a pneumatic directional control valve designed to manage compressed air flow in industrial automation and manufacturing equipment. Manufactured by MAC Valves, this air-operated valve provides directional switching for compatible pneumatic cylinders, actuators, and compressed air control systems.

Featuring a spring return mechanism, this 4-way pneumatic valve returns to its designated default position when the actuating signal is removed. The 1/4-inch port connections allow integration into compatible industrial pneumatic systems requiring directional airflow control.

What Is a 4 Way Spring Return Valve?

A 4 way spring return valve is a pneumatic directional control component used to regulate airflow between ports within a compressed air system.

When a pneumatic pilot signal actuates the valve, the internal mechanism changes position to redirect airflow. Once the actuating signal is removed, the spring return mechanism shifts the valve back to its default position.

This operation makes spring return valves useful for equipment requiring a defined resting position and controlled pneumatic switching.

Why Choose a MAC Spring Return Valve?

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

The 1/4-inch spring return configuration provides a solution for compatible pneumatic systems requiring directional airflow control and air-operated valve actuation.

When selecting a replacement valve, confirm the model number, port dimensions, pressure requirements, and actuation configuration to ensure compatibility with your equipment.
