| Application
A lift check valve is used to prevent the backflow of any stream, whether it is liquid, gas, vapor, or any solidified stream. There is a certain pressure required to open the check valve. If the pressure becomes less, the valve will automatically close, or additionally, it prevents the stream from flowing in the opposite direction. |

The carefully selected materials and contemporary design make our check valve highly recognized. If our check valve cannot meet your choice, we can provide you with special made. |

Controlled by a plug that lifts as the valve fills up with media, the Lift Check Valve (or Piston Check Valve) is ideal for gas, liquid, air, and vapor pipeline connections. Available in horizontal, vertical, and angular body patterns, our lift check valves keep released media from returning when the plug returns to its original place.
The valve can be opened and closed automatically by medium force
Ss+ graphite or metal seal is used between valve body and valve cover, and the sealing is reliable
The sealing surface of valve seat and disc is overlaid with cemented carbide to improve the scouring resistance and prolong the service life of the valve
Lift check valve disc can also be spherical at high pressure

| Application
The swing check valve is used in various mediums like steam, water, nitric acid, oil, solid oxidizing media, acetic acid, and urea. These are generally used in chemical, petroleum, fertilizer, pharmaceutical, power, and other industries. However, these valves are suitable for cleaning and not for those mediums that contain very high impurities. |

Swing check valves feature a weighted disc that swings forward to allow media to flow and moves back to the initial position for tight sealing. Easy to install and maintain, these swing check valves effectively prevent media overflow and are perfect for high-pressure applications.
The structure of these valves is compact and simple
These valves are sensitive to minor changes in pressure, which enhances the sealing performance of the valve.
They have a disc stroke that reduces the valve closing impact
The valve also has a rocker arm
We are leading swing valve manufacturers who are known for providing top-quality products.
