Application
Swing Check Valve is suitable for clean medium. It should not be used for medium containing solid particles or high viscosity. Swign check valve's fluid resistance is generally less than the lift check valve. so it is suitable for large bore application.
Structure Features:
1.Full bore design.Fluid pressure is almost unimpeded when the swing check valve is in fully open condition;
2.Disc could be removed as a whole, effectively reducing the workload of site maintenance;
3.The maintenance-free design eliminates the need for maintenance during the service life;
4.The sealing face is made of hard alloy with great erosion resistance;
5.With Integral forged body the valve could be applied in all pressure ratings;
6.Straight-through structure reduces erosion from medium to valve body.
