Parker 410811000 4 Way 2 Position Toggle Air Valve

Product Description

The PARKER 410811000 is a manually operated, mechanically actuated directional control valve designed for pneumatic systems. Built on a 4-way, 2-position design, it uses a toggle actuator with spring return to direct compressed air flow between ports. With a Cv rating of 0.2, it is suited for low-flow pneumatic circuits requiring direct manual control. This valve accepts NPT threaded connections and is rated for operation beginning at 32 degrees F. It is commonly installed by pneumatic system technicians, maintenance mechanics, and industrial equipment technicians in light-duty air control applications.

This valve fits into pneumatic control circuits where an operator needs to manually shift airflow direction between two states. Typical applications include actuating small pneumatic cylinders, directing air to pilot-operated devices, or switching between two air circuit branches. The toggle actuation mechanism provides a positive, tactile shift feel, while the spring return ensures the valve returns to its default position when the toggle is released. It is appropriate for both production equipment and maintenance panel installations where direct manual intervention is required.

Key Features

• 4-way, 2-position valve design for directional pneumatic flow control
• Toggle actuator with spring return activation for reliable manual operation
• Cv rating of 0.2 for low-flow pneumatic circuit applications
• NPT threaded port connections for standard pneumatic plumbing
• Minimum working temperature of 32 degrees F
• Compact and lightweight at 0.5 pounds for easy panel or inline mounting

Compatibility

Designed as an OEM-style replacement or direct-install manually operated directional control valve for pneumatic systems using NPT-threaded connections and low-flow compressed air circuits.

Installation Notes

Installation should be performed by a qualified pneumatic technician or maintenance mechanic. Depressurize and lock out the compressed air supply before installing or servicing this valve. Ensure all NPT threads are properly sealed with thread sealant tape or compound rated for compressed air service. Verify that system operating pressure and temperature remain within the valve's rated limits before returning the circuit to service.
