Check Valve,O-Ring Poppet Valve - CO Series
*PRODUCT IMAGE IS REPRESENTATIVE PROVIDED BY THE MANUFACTURER. DO NOT MAKE BUYING DECISIONS SOLEY BASED ON THE IMAGE. PLEASE VERIFY SPECIFICATIONS MEET YOUR REQUIREMENTS.
Parker’s CO Series Check Valves are designed for high integrity, leak proof systems with uni-directional flow control of critical fluids and gases up to 6,000 PSI (414 BAR). These inline check valves are suitable for instrumentation applications requiring high integrity leak rates and re-sealing capabilities.
Markets:
• Microelectronics
• Research
• Chemical Processing
• Pharmaceutical
Features/Benefits:
• Seal integrity across the seat and to atmosphere is tested to 4 x 10-9 std atm-cc/sec (4 x 10-10 kPa – L/sec) for the CO4L with fluorocarbon rubber seals. All other sizes and seal materials are tested to 1 x 10-5 std tm-cc/sec (1 x 10-6 kPa – L/sec).
• Special seat seal design provides a repeatable high integrity seal and accurate cracking pressures
• 100% factory tested. Cracking pressures include:
• 1/3, 1, 5, 10, 25, 50, 75, and 100 psi.
• Valves are available with male and female NPT, CPI™, A-LOK®, UltraSeal, male and female VacuSeal, and Tube Adapter ends
• Heat code traceability
• Color coded identification labels indicate seal material
Applications:
• Fill systems
• Back Flow Preventers
