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;
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.
Stem: Stainless Steel
Spring: Stainless Steel
Seat: EPDM, NBR, Stainless Steel
Size: DN40-DN600mm PN1.0-1.6MPa
Working temperature: -196℃ - +560℃
Body: Cast Iron, Ductile Iron, Carbon Steel, Stainless Steel
It is opened or closed by the valve clack moving to-and-fro through the valve body guiding axle under the spring effect.
The valve body passageway is designed in a wing-shaped streamline type, allowing the medium to flow through the passageway rapidly and steadily with no noise.
It can be installed on horizontal and vertical pipelines.
