Product Information
Full details
This manual 3/2-way shut off valve from Festo (MPN: HE-D-MINI) is designed for technical professionals needing reliable pneumatic control for pressurizing and exhausting installations. Its key benefit is versatile exhaust management, allowing for muffler or ducted options, alongside clear visual indication of switching position for enhanced safety. A potential caveat is its manual operation, requiring direct user input for function. This valve offers robust performance within a wide pressure range and is constructed with durable materials.

FAQs
What is the maximum operating pressure for this valve?
The Festo HE-D-MINI shut off valve can operate at a maximum pressure of 16 bar.
Can I automate the operation of this valve?
This is a manual shut off valve, meaning it requires direct physical actuation of the control button. It is not designed for automated or solenoid control.
What type of pneumatic media can be used?
This valve is designed for use with standard, filtered, and lubricated or non-lubricated pneumatic air.
How do I connect tubing to the valve?
The valve features a G 1/8 connection port thread, meaning it is compatible with standard pneumatic fittings designed for 1/8 inch threads.
What are the options for the exhaust port (port 3)?
You can either attach a compatible muffler to port 3 to reduce noise or connect a duct to route the exhaust air elsewhere.
What is the operating temperature range?
The valve is designed to operate reliably within a temperature range of -10°C to +60°C.
How can I tell if the valve is open or closed?
The valve features a clearly visible switching position indicator on its blue control button, allowing you to easily see its current state.
Troubleshooting
Valve does not switch positions
Verify that the control button is being pressed firmly. Ensure there are no obstructions preventing the button movement. Check if system pressure is within the operating range (0-16 bar).
Air leakage from port 3 (exhaust)
If the valve is intended to hold pressure (not exhaust), ensure the button is fully engaged in the closed position. Check for debris on the valve seat or seals. If leakage persists, the internal seals may be worn.
Reduced airflow to the actuator (port 2)
Confirm that the inlet pressure (port 1) is adequate. Check for blockages in the valve's internal passages or the connected tubing. Ensure the valve is fully opened.
Muffler or ducting connected to port 3 is ineffective
Ensure the muffler or duct is properly attached and not blocked. Verify that the valve is indeed switching to allow exhaust through port 3.
Pros and Cons
Pros
- Versatile exhaust options (muffler or ducted)
- Clear visual indicator for valve status
- Wide operating pressure range (0-16 bar)
- Durable aluminium construction
- Suitable for manual control applications
Cons
- Manual operation requires direct user intervention
- Limited to 3/2-way functionality
- Control button color is fixed (blue)
Setup, Compatibility & Care
Setup:
- Identify the desired port for connection (typically port 1 for inlet, port 2 for outlet/actuator, port 3 for exhaust).
- Ensure the pneumatic system pressure is within the 0 to 16 bar range.
- Connect the air supply to port 1 using appropriate fittings for the G 1/8 connection thread.
- Connect the actuator or downstream pneumatic line to port 2.
- For exhaust control, either attach a compatible muffler to port 3 or connect a duct for directed venting.
- Confirm the control button is in the desired initial position (e.g., closed to isolate).
Compatibility:
- Thread Size: Compatible with G 1/8 pneumatic fittings.
- Pressure: Suitable for systems operating between 0 and 16 bar.
- Temperature: Operates reliably between -10°C and +60°C.
- Fluid: Designed for use with standard pneumatic air.
Care:
- Regularly inspect the valve for any signs of physical damage or leaks.
- Ensure that any attached mufflers or exhaust ducts are clean and free from obstructions.
- Avoid exposing the valve to abrasive materials or chemicals not compatible with aluminium and its seals.
- In dusty environments, periodically clean the exterior of the valve with a dry or slightly damp cloth.
