Essence: A type of ultra-thin automatic check valve that drives the valve disc (disc or single disc) to quickly open and close by the flow pressure of the medium itself, achieving one-way flow and preventing medium backflow. It belongs to the branch category of clamp type check valves.

Core design features:

Ultra thin and compact: The valve body structure is short and lightweight (only 1/4~1/8 the length of traditional check valves), using a clamp type connection, suitable for installation in pipelines with limited space;

Quick response: The valve disc achieves vertical lifting/rotating motion through spring assistance or self weight. It opens with low resistance when flowing forward and quickly closes when flowing backward, effectively reducing water hammer impact;

Reliable sealing: The valve disc is equipped with O-ring or hard alloy sealing surface to achieve zero leakage sealing, and the durability can reach more than 10 years;

Low flow resistance design: Smooth flow channel, sensitive valve disc action, and can fully open under low pressure difference.

Typical applications:

Scenario: Pipelines in water supply systems, petrochemicals, HVAC engineering, etc. that require backflow prevention and have limited installation space;

Media: water, steam, oil, and non corrosive fluids.
