SWAGELOK Fitting SS-6C-MM-1/3

Every C, CA, CH, CP, and CPA series check valve is factory tested for crack and reseal performance.

Check valves with fixed cracking pressures, C, CP, and CH series, are cycled six times prior to testing. Seats have a maximum allowable leak rate of 1 std cm3/min nitrogen.

Check valves with adjustable cracking pressures, CA and CPA series, are tested at two pressure points. Every valve is tested at a low-pressure setting and at a high-pressure setting. Seats have a maximum allowable leak rate of 1 std cm3/min nitrogen.

Every C, CA, and CH series check valve with VCR® or VCO® end connections is processed in accordance with Swagelok Special Cleaning and Packaging (SC-11), MS‐06‐63, to ensure compliance with product cleanliness requirements as stated in ASTM G93 Level C.

All other C, CA, and CH series check valves, as well as every CP and CPA series check valve, are cleaned.
