The check valve on the clip-type check valve installed in the pipeline system, its main role is to prevent media backflow, check valve is a medium pressure to rely on to open and close the automatic valve. The check valve on the folder for the nominal pressure PN1.0MPa ~ 42.0MPa, Class150 ~ 25000; nominal diameter DN15 ~ 1200mm, NPS1 / 2 ~ 48; Operating temperature -196 ~ 540 ℃ on the various pipelines, to prevent Media backwards. Through the selection of different materials, can be applied to water, steam, oil, nitric acid, acetic acid, strong oxidizing media and uric acid and other media. The main material on the wafer check valve: carbon steel, low temperature steel, duplex steel (F51 / F55), titanium alloy, aluminum bronze, INCONEL, SS304, SS304L, SS316, SS316L, Steel, Monel (400/500), 20 # alloy, Hastelloy and other metal materials. Clamp check valve standards and specifications 1, design and manufacture: API594, API6D, JB / T8937 2, the length of the structure: API594, API6D, DIN3202, JB / T8937 3, pressure, temperature class: ANSI B16.34, DIN2401 GB / T9124, HG20604, HG20625, SH3406, JB / T74 4. Test and Inspection: API598, JB / T9092 5. Piping flange: JB / T74-90, GB / T9112-9124, HG20592-20635, SH3406, ANSI B 16.5, DIN2543-2548, GB / T13402, API605, ASMEB16.47 Clamp check valve structure features 1, the structure of short length, the length of the structure only traditional flange check valve 1/4 ~ 1/8 2, Small size, light weight, the weight of only traditional flange check valve 1/4 ~ 1/20 3, the valve closed quickly, water hammer pressure is small 4, horizontal or vertical pipe can be used, easy to install 5, the flow Road, smooth, small fluid resistance 6, sensitive action, good sealing performance 7, the valve stroke is short, close the impact of small 8, the overall structure is simple and compact, handsome in appearance 9, long life, reliable performance
