Prevent backflow: Ensure one-way flow of the medium to avoid backflow.
Reduce noise: Reduce the impact sound and water hammer effect during valve opening and closing through special design.
Automatic operation: relying on the pressure of the medium to automatically open and close, without the need for external control.
Compact structure: easy to install and takes up minimal space.

Y-Type Check Valveis a type of valve used to prevent fluid backflow, named after its Y-shaped valve body. It allows fluid to flow in one direction, and when the fluid flows in the opposite direction, the valve automatically closes to prevent backflow.
There are two main types of forged steel check valves: forged steel swing check valves and forged steel lift check valves. The quality of forged steel parts is higher than that of cast steel parts, and they can withstand large impact forces. Their plasticity, toughness, and other
An energy-saving multi-combination control valve without external energy sources, used for flow and temperature control devices for non-corrosive liquids with a maximum temperature of 350℃, as well as pressure and differential pressure control devices, and flow and pressure control devices for liquids, gases and steam.
