What is Lift Check Valve?
Check valves are designed to prevent the reversal of flow in a piping system. These valves are activated by the material flowing through the pipeline.
Fluid pressure opens the valve, while any reversal of flow closes it. Closure can be achieved by the weight of the check mechanism, back pressure, a spring, or a combination of these methods. The main types of check valves include swing, tilting disk, piston, butterfly, and stop check valves.
A lift check valve is commonly used in piping systems where globe valves are employed as flow control valves, as they share similar seating arrangements.
Lift check valves can be installed in horizontal or vertical lines with upward flow. They are recommended for use with steam, air, gas, water, and vapor lines that have high flow velocities.
These valves are available in three body patterns: horizontal, angle, and vertical.
Flow to lift check valves must always enter from below the seat. As the flow enters, the disk or ball is lifted from the seat by the pressure of the upward flow, guided within the valve.
When the flow stops or reverses, the disk or ball is pushed back onto the seat by both the back-flow and gravity, effectively closing the valve.
Some types of lift check valves can be installed horizontally. In these designs, the ball is supported by a system of guide ribs, which is commonly used in plastic check valves.
The seats of metallic body lift check valves are either integral with the body or have renewable seat rings.
The disk construction is similar to that of globe valves, featuring either metal or composition disks.
Metal disks and seats in these valves can be reconditioned using the same techniques as those used for globe valves.

02
Required Flow Rate
When buying a Lift Check Valve, it’s important to confirm that it can handle the specific flow rate required by your system. Let me explain. For example, if your system operates at 10 gallons per minute (GPM), choose a valve designed to accommodate this flow rate. This is crucial to maintaining efficient fluid movement and preventing pressure drops, which could compromise system performance and efficiency.
03
Cv Range (1-10)
When buying a lift check valve, look for a CV range of 1-10. The CV value tells you how much fluid the valve can handle. For example, if your system needs to move a small amount of water without causing a big drop in pressure, a CV range of 1-10 is ideal to keep the flow steady and efficient.
