Short structural length,only 1/4~1/8 of that of traditional flanged check valve; Low volume,light weight,only 1/4~1/20 of those of traditional flanged check valve; Quick valve disc closedown,low water hammer pressure; Applicable for and easily installed for vertical or horizontal pipelines; Smooth flow passageway and small fluid resistance; Flexible action and good sealing performance; Narrow valve travel and small closedown impact; Integrated structure,simple and compact,in beautiful shape; Long service life and good reliability.
Wafer Type Single Plate Swing Check Valve(Long Type)
Check Valve is applicable for various pipelines with nominal pressure of PN1.0MPa~42.0 MPa, Class150~2500 and nominal diameter of DN15~1200mm, NPS1/2-48 and working temperature of -196~540℃ to be used for protecting from medium back flowing.
The different materials selection can apply to the medium involving water, steam, oils, nitric acid, strong oxidizing medium and urea etc.
End Connection: RF, RTJ, BW
Nominal diameter: 2" ~ 24" (DN15 ~ DN600)
Pressure range: Class 150 ~ 900 (PN16 ~ PN150)
Working temperature: -196℃ ~ +560℃
Body material: Carbon steel, Stainless steel, Alloy steel, Bronze, etc
Applicable Medium：Air, Oil, Steam, Water, etc
The valve is opened/closed by the valve disc moving in a direction parallel to the valve seat hole axis and can only be installed on horizontal pipelines with the major function of preventing medium backflow when shutting down the pump and maintaining the water column required by pumping.
