Lift Check Valve

A lift check valve

A lift check valve is used to prevent back flow into a stream.

The valve is used mainly in water applications because of its design.

The pressure of the media is what is used to open the lift check valve, which starts off in a normally closed (NC) position. 

A lift check valve's process is fully automated because it depends on gravity and the pressure of the media to work.

As the pressure increases and reaches its optimal rate, the disk will begin to lift off of the seat, allowing flow to pass through the valve.

As the pressure decreases, the cone (assisted by gravity) will begin to return to its original position. 

As the cone reaches its original starting position, the seal will close and flow wont be able to pass through the valve. 

Gravity is a large factor in operating a lift check valve, this is why the valve must be used in a horizontal position.

Some uses of lift check valves would be:

Used to prevent the back flow of condensation in steam traps.

Can be used on outlets of cyclic condensate pumps.

The areas of industry where lift check valves can be used is large and very varied.

These industries can range from:

• Domestic use
• Pumps
• Industrial process
• Pipelines
• Oil and gas
• Food and beverage
• Biopharm industry
• Marine industry
