Poppet check valve CO Series

threadedflow controlstainless steel

Parker's CO Series check valves are designed for uni-directional flow control of critical fluids and gases in industries such as pharmaceutical,research and microelectronics. 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
