Description

Clippard MJV-3 3-Way Normally Closed Pneumatic Valve

The Clippard MJV-3 3-Way Normally Closed Valve is a mechanically operated pneumatic directional control valve designed to manage compressed air flow in industrial machinery and automation equipment. Manufactured by Clippard, this compact valve features a brass body, mechanical stem actuation, and a normally closed configuration for controlling compatible pneumatic circuits.

The MJV-3 valve allows machinery to control compressed air through a mechanical input rather than an electrical solenoid. When the valve stem is actuated, the internal mechanism changes the airflow path, allowing compressed air to reach connected equipment. When the actuator is released, the valve returns to its normal position.

Its compact design makes the Clippard MJV-3 suitable for equipment requiring mechanically triggered pneumatic control, including manufacturing machinery, automation systems, and industrial equipment maintenance.

Key Features & Benefits

• 3-Way Directional Control: Manages compressed air through inlet, outlet, and exhaust functions.
• Normally Closed Operation: Blocks supply airflow to the outlet in its normal, unactuated position.
• Mechanical Stem Actuation: Operates through physical movement of the valve stem without electrical power.
• Automatic Reset: Returns to its normal position when the mechanical actuating force is removed.
• Brass Valve Body: Features durable metal construction for compatible industrial pneumatic applications.
• Compact Design: Suitable for installation in machinery where space is limited.
• Industrial Replacement Part: Useful for maintaining equipment requiring a matching Clippard MJV-3 valve.

How Does a 3-Way Normally Closed Pneumatic Valve Work?

A 3-way normally closed pneumatic valve controls the flow of compressed air between three connections: an inlet, an outlet, and an exhaust.

The operating process generally follows four steps:

1. Normal Position: With the actuator released, the inlet is closed and the outlet can exhaust air.
2. Mechanical Activation: A machine component, cam, or other mechanical actuator depresses the valve stem.
3. Airflow Switching: The internal valve mechanism opens the compressed air supply path to the outlet.
4. Valve Reset: When the mechanical force is removed, the spring-loaded mechanism returns the valve to its normal position.

This process allows industrial equipment to activate pneumatic functions through direct mechanical movement.

Common Applications

The Clippard MJV-3 valve can be used in compatible industrial pneumatic systems, including:

• Manufacturing and assembly machinery

What Is a Normally Closed Pneumatic Valve?

A normally closed pneumatic valve prevents compressed air from flowing from the supply port to the outlet when the valve is not actuated.

When the valve receives its mechanical input, the internal mechanism changes position and allows compressed air to flow to the connected equipment.

Once the mechanical input is removed, the valve returns to its normal state, stopping the supply flow and allowing the outlet to exhaust according to the valve configuration.

Normally closed valves are commonly used in automated machinery where pneumatic functions must respond to mechanical movement or equipment positioning.

Why Choose a Clippard MJV-3 Valve?

Clippard manufactures pneumatic control components for industrial automation, fluid power, and manufacturing applications.

The MJV-3 provides a compact, mechanically operated solution for controlling compressed air without requiring an electrical solenoid. Its normally closed operation makes it useful for compatible pneumatic control systems requiring a defined resting state.

When replacing an existing valve, confirm the model number, port configuration, mounting requirements, and operating pressure to ensure compatibility with your equipment.
