The GKEEMARS FV-320 is a 2-position, 3-way pneumatic foot pedal valve designed for controlling air flow in various pneumatic systems. It features a durable aluminum construction, a non-slip rubber pedal, and a built-in silencer for the exhaust port.

2. Product Features

• Durable Construction: Made from high-quality aluminum for longevity and reliability.
• Non-slip Pedal: Features a textured rubber pad to prevent accidental slipping during operation, enhancing safety and efficiency.
• Robust Spring Mechanism: Equipped with a stainless steel spring for strong strength, good resilience, and resistance to rust.
• 2 Position 3 Way Operation: Provides precise control over pneumatic circuits, allowing for air intake, air outlet, and exhaust.
• Built-in Silencer: The exhaust port includes a silencer to reduce operational noise.
• Standard Thread Size: PT1/4" NPT threaded ports for easy integration into existing pneumatic systems.

4. Setup and Installation

1. Safety First: Ensure that the pneumatic system is depressurized and locked out before beginning any installation work. Wear appropriate personal protective equipment (PPE).
2. Mounting: Position the foot pedal valve in a stable location where it can be operated safely and comfortably. The valve can be mounted to a floor or a suitable surface using appropriate fasteners (not included).
3. Connect Air Supply: Connect the main air supply line to the "IN" port (Port 2 in Figure 3) of the valve. Ensure connections are secure and leak-free. Use thread sealant if necessary.
4. Connect Actuator/Tool: Connect the air line leading to your pneumatic actuator or tool to the "OUT" port (Port 3 in Figure 3) of the valve.
5. Exhaust Port: The exhaust port (Port 1 in Figure 3) has a built-in silencer and typically does not require an external connection. Ensure it is clear of obstructions.
6. Test System: Slowly re-pressurize the pneumatic system and check all connections for leaks. Operate the pedal a few times to ensure proper function before full use.

Note: The valve is designed for a working pressure range of 0-114 Psi. Do not exceed the maximum rated pressure.

5. Operating Instructions

The GKEEMARS FV-320 is a 2-position, 3-way valve, meaning it has two stable states (pressed or released) and three ports (input, output, exhaust) that control air flow.

• Pedal Released (Default Position): In its resting state, when the pedal is not pressed, the air supply from the "IN" port is blocked, and the "OUT" port is connected to the exhaust port. This typically allows the connected pneumatic device to return to its default position (e.g., a cylinder retracts).
• Pedal Pressed (Activated Position): When the foot pedal is fully pressed down, the air supply from the "IN" port is connected to the "OUT" port, allowing pressurized air to flow to the connected pneumatic device. Simultaneously, the exhaust port is blocked. This activates the pneumatic device (e.g., a cylinder extends).

Figure 5: Illustration of the pedal's operation: pressing down activates the air flow, releasing stops it.

To operate, simply press the pedal with your foot to activate the pneumatic function, and release the pedal to return the system to its default state.

6. Maintenance

Regular maintenance helps ensure the longevity and reliable operation of your foot pedal valve.

• Cleaning: Periodically clean the exterior of the valve with a damp cloth. Avoid using harsh chemicals or abrasive cleaners.
• Check for Leaks: Regularly inspect all pneumatic connections for air leaks. Leaks can reduce system efficiency and put strain on components.
• Inspect Pedal: Check the rubber non-slip pad for wear or damage. Ensure the pedal mechanism moves freely without sticking.
• Exhaust Port: Ensure the exhaust port (with built-in silencer) remains clear of debris to prevent back pressure and ensure proper operation.
• Air Quality: Ensure the air supply is clean and dry. Contaminants in the air can damage internal valve components over time. Consider using an air filter/regulator/lubricator (FRL) unit upstream of the valve.

Note: Internal components are not user-serviceable. Do not attempt to disassemble the valve, as this may void any potential warranty and could lead to damage or improper function.
