Lift Check Valve

Cast Steel Russia Standard Flange End 1.0/1.6/2.5 Mpa Lift Check Valve Introduction H41h and H41W cast steel lift check valves are widely used for nominal pressure PN1 For pipelines under various working conditions such as petroleum, chemical industry and thermal power station with working temperature of - 29 ~ 550 ℃ at 6 ~ 10.0MPa, the applicable media are water, oil, steam, etc. Its main function is to prevent medium backflow, reverse rotation of pump and its driving motor,

Cast Iron Pressure 10/16 Mpa Flange End Ball Check Valve Lift Check Valve Introudction The rubber ball adopts hollow steel ball and is attached with rubber with good elasticity, which can ensure the sealing and reduce the damage to the pipeline system during valve closing. When the valve is opened, the conical body with holes can fix the steel ball, eliminate the pressure on the contact surface between the rubber ball and the conical body, make the contact surface contact,

Gost Stainless Steel 1.6/2.5/4.0/6.4 Mpa Flange End Lift Check Valve Introduction This valve is suitable on the nitric acid type pipeline does prevents the medium adverse current to open one way shuts. Installation mode 1.for the check valve with the valve disc sliding along the vertical center line of the valve body, the internal thread check valve can only be installed on the horizontal pipeline, and the valve disc on the high-pressure small-diameter check valve can adopt a

Cast Iron Pressure 10K Foot Valve Flange End Lift Check Valve Introduction The bottom valve, also known as the check valve, is a low-pressure flat valve. Its function is to ensure the one-way flow of liquid in the suction pipe to make the pump work normally. When the pump stops working for a short time, the liquid cannot return to the water source tank, so as to ensure that the suction pipe is full of liquid, so as to facilitate the start of the pump characteristic The bottom

PN16 DN15-DN250 Cast Carbon Steel Flanged Ends Lift Check Valve introduction Lift check valve refers to the valve that automatically opens and closes the valve disc depending on the flow of the medium itself to prevent the backflow of the medium. It is also known as check valve, one-way valve, reverse flow valve and back pressure valve. The check valve belongs to an automatic valve, which is mainly used to prevent medium backflow, reverse rotation of pump and driving motor,
