Lift Check Valve product description
Lift Check valves are suitable for using on various kinds of pipeline from Class150 To Class900, PN20 To PN150 to cut off or connect the flowing of medium. By using different material, the Lift Check Valve could be suitable for medium such as water, steam, oil, nitric acid, acetic acid, oxidizing substance, carbamide and etc.
Lift Check valve could only be installed on horizontal pipeline. And ball shaped disc would be used for Small size high pressure lift check valve. Guiding slot is machined both on the upper part of disc and down part of bonnet with which the disc could move smoothly in the valve. The disc would open with the force of flowing medium and closed to prevent the back flowing with both the force of back flowing medium and disc's own gravity. Lift check valve has a large flowing resistance as having the similar structure with Globe valve. Carbon steel lift check valve could be used for medium such as water, steam, gas, while the stainless steel check valve could be suitable for corrosive medium such as Food, oil, Pharmacy and etc.
