Q1: What is the FUJIKURA VC-P Series?
A: The VC-P Series is a low-pressure, low-cracking-pressure resin check valve that prevents clean compressed air or water from flowing backward from the outlet to the inlet.
Q2: What is the standard VC-P model?
A: The standard model is VC-P-4-E.
Q3: What is the cracking pressure?
A: The cracking pressure is 1kPa or less, making it suitable for low differential-pressure conditions.
Q4: What is the leakage rate?
A: Leakage is 1mL/min or less at 10kPa.
Q5: What fluids can the VC-P Series handle?
A: It supports clean compressed air and water. Material compatibility should be confirmed before using other liquids.
Q6: What materials are used?
A: The body is Polyacetal, while the umbrella and O-ring are EPDM.
Q7: What tube size does the VC-P Series use?
A: Standard model VC-P-4-E uses a Tube ID Φ4 connection.
Q8: What is the working pressure?
A: The working pressure is 200kPa, and the proof pressure is 250kPa max.
Q9: What are the product dimensions?
A: The outside diameter is approximately Φ18mm, and the overall length is approximately 35mm.
Q10: What applications is the VC-P Series suitable for?
A: It is suitable for medical equipment, endoscope washing systems, oxygen concentrators, anesthesia machines, analyzers, water-treatment equipment, and compact gas-generator lines.
