Extended Product Information
FAQs
What is the main application for this control block?
This control block is primarily used as a safety valve in industrial applications, such as press safety, compliant with standards like ISO 16092-4.
What are the required operating pressure limits?
The valve requires a minimum operating pressure of 3 bar and can handle a maximum operating pressure of 10 bar.
What type of actuation does this valve use?
This is a monostable valve actuated by a solenoid, meaning it returns to its default position when the electrical signal is removed.
What is the flow rate of this valve?
The valve has a nominal flow rate of 950 liters per minute (l/min).
What are the pneumatic connection sizes?
The pneumatic connections are G1/4 size.
What is the temperature range for operation?
The valve can operate within a temperature range of -5°C to +50°C.
What is the power consumption of the solenoid?
The solenoid has a power consumption of 1.8W.
Troubleshooting
Valve does not actuate when signaled
Check the electrical connection to the solenoid. Verify the supply voltage is correct and that the solenoid is not damaged. Ensure the minimum operating pressure of 3 bar is met.
Leaking air
Inspect all pneumatic connections (G1/4 ports) for tightness and integrity. Check for damaged seals or internal valve components. Ensure the operating pressure does not exceed the maximum of 10 bar.
Slow response time
Verify that the pneumatic supply line is adequately sized and free from obstructions. Ensure the control signal is stable and consistent. Check that the operating pressure is within the optimal range.
Valve fails to return to the monostable (default) position
Ensure the electrical signal to the solenoid has been removed. Check for any mechanical obstructions preventing the spring return. Verify the internal mechanism is not jammed.
Pros and Cons
Pros
Enhanced industrial safety with a redundant design.
Compliant with key international safety standards.
High flow rate ensures efficient pneumatic operation.
Robust construction suitable for demanding environments.
Versatile operation within a standard industrial pressure range.
Cons
Monostable design means it relies on a spring return.
Requires a minimum operating pressure of 3 bar to function.
Operating temperature range is limited to -5°C to +50°C.
Solenoid power consumption of 1.8W needs to be factored into system power planning.
Setup, Compatibility & Care
Setup:
Ensure the pneumatic supply pressure is within the 3-10 bar range.
Connect pneumatic lines to the G1/4 ports, ensuring proper sealing to prevent leaks.
Connect the electrical control signal to the solenoid, observing correct polarity if applicable.
Verify that the valve's mounting is secure and vibration-free.
Compatibility:
This valve is designed for pneumatic systems operating within the specified pressure and temperature ranges.
It is compatible with control systems that can provide the necessary electrical signal to the solenoid.
Ensure all connected pneumatic tubing and fittings are rated for the operating pressure and temperature.
Care:
Regularly inspect the valve for any signs of physical damage or leakage.
Keep the surrounding area clean to prevent dust or debris from entering pneumatic lines.
Avoid exposing the valve to temperatures outside its -5°C to +50°C operating range.
Perform periodic checks of pneumatic connections to ensure they remain tight.
