FUJIKURA FCAM Adjustable-Cracking-Pressure Check Valve

• Adjustable cracking pressure: Cracking pressure can be adjusted according to equipment requirements for testing and piping control.
• High-pressure capability: The maximum working pressure is 20MPa, and the proof pressure is 30MPa for high-pressure gas and liquid piping.
• Ideal for prototypes and research: The series is suitable for small-volume use, prototype machines, research equipment, and applications requiring flexible cracking-pressure settings.
• Two body materials: Brass and SUS316 body options are available, with FKM as the standard seal material.
• Compact lightweight design: The simplified body structure is available in R1/4 and R1/2 sizes for installation in equipment piping.

Q1: What is the FUJIKURA FCAM Series?
A: The FCAM Series is a check valve with adjustable cracking pressure that prevents compressed air or liquid from flowing backward from the outlet to the inlet.

Q2: What fluids can the FCAM Series handle?
A: It supports compressed air and liquids, but compatibility with the body and seal materials should be confirmed before selection.

Q3: What is the maximum working pressure?
A: The maximum working pressure is 20MPa, and the proof pressure is 30MPa.

Q4: What body materials are available?
A: Brass and SUS316 bodies are available, represented by model codes B and T.

Q5: What pipe port sizes are available?
A: R1/4 and R1/2 pipe ports are available, represented by model codes 2 and 4.

Q6: What cracking pressure ranges are available?
A: Depending on the spring code, ranges of 20 to 100kPa, 110 to 350kPa, 360 to 1000kPa, 1010 to 2400kPa, or 2410 to 4100kPa are available.

Q7: How is the cracking pressure specified?
A: Add the specified cracking pressure after the spring code. For example, FCAMB2V-B-300 specifies a cracking pressure of 300kPa.

Q8: How is the FCAM cracking pressure adjusted?
A: Loosen the fixed nut with a hex wrench, adjust the pressure-control nut, turn clockwise to increase pressure or counterclockwise to decrease it, then lock the nut and confirm the cracking pressure.

Q9: Is the adjustment tool included?
A: No. The adjustment tool is not included. R1/4 models use a 4mm hex wrench, and R1/2 models use an 8mm hex wrench.

Q10: What applications is the FCAM Series suitable for?
A: It is suitable for prototype machines, research equipment, high-pressure gas and liquid piping, machine tools, industrial furnaces, medical equipment, analyzers, water-treatment equipment, compressors, and applications requiring reverse-flow prevention with adjustable cracking pressure.
